What Is Mean By Schedule Lines

What is mean by schedule lines?
Explain the schedule lines in md02?

1. no schedule lines
2. schedule lines in opening period
3. schedule lines

Schedule lines are created against schedule agreements. Say if you have a material which is procured from subcontract. If you want the delivery in particular days with schedule you can maintain schedule agreeement. In source list you will maintain vendor, schedule agreeement with validity dates and which agreement is relevant for mrp.

If you maintain 2 against the sch agreemetn mrp will generate schedule line which you can see in md04. Also this delivery schedules are updated in scheduling agreement (t cod ME33). When running mrp in initial screen delivery schedules--you have to maintain 3 create schedule line

Schedule line in opening period - Opening period is maintained in Configuration of "Schedule Margin Key" which is getting assigned to Material master in MRP2 view.

Your understanding of the result after MRP is needed.

Define Floats (Scheduling Margin Key)

In this step, you specify the floats for determining the basic dates of the planned orders. The floats are allocated to the material via the release period key in the material master record.

Opening period

The opening period represents the number of workdays that are subtracted from the order start date in order to determine the order creation date. This time is used by the MRP controller as a float for converting planned orders into purchase requisitions or into production orders.

Float before production

The float before production represents the number of workdays that are planned as a float between the order start date (planned start date) and the production start date (target start date). On the one hand, this float is intended to guarantee that delays in staging a material do not delay the production start. On the other hand, the production dates can be brought forward by means of the float to cope with capacity bottlenecks.

Float after production

The float after production should provide a float for the production process to cope with any disruptions so that there is no danger that the planned finish date will be exceeded. You plan the float after production between order finish date (planned finish date) and scheduled end (target finish date).

Release period

The release period represents the number of workdays that are subtracted from the order start date in order to determine the production order release. The release period is only relevant for production order management. Recommendation

The opening period should reflect the processing time the MRP controller needs to convert planned orders into purchase requisitions or production orders. The opening period should be at least as long as the interval between two MRP intervals, so that all planned orders can be taken into account during the conversion.

Scheduling-5

What is Finite and Infinite Scheduling

What is finite and infinite scheduling? How it is carried out? What is to be done for each one? What are their significance?

Differences between planning and scheduling, finite and infinite

Finite Scheduling
Scheduling type within capacity planning that takes account of the capacity loads which already exist. Finite scheduling calculates the start and finish dates for operations in the order. It is a detailed scheduling strategy with which you schedule orders and operations, taking into account the existing resource load. A resource overload cannot occur.

Infinite Scheduling
A detailed scheduling strategy with which you schedule orders and operations, without taking into account the existing resource load. It is therefore possible for resource overloads to occur.

R/3 does planning without consideration for capacity situations. So if MRP says you need 500 parts on 3/1/04, it schedules them all to be built at the same time, even though you can only do 100 at a time. Assume you have a fixed lot size of 100, you'll get 5 planned orders for 100 to start on the same day. This is "Infinite Planning". APO would recognize that constraint, and instead schedule out the 5 orders over time. The important part of that is that it also will schedule out the deliveries of the components for 5 different days. This is "Finite Planning".

Now, assume old fashion MRP. It schedules all 5 orders for the same day, and the buyers go out an get all of the components for the same day. Then the planner realizes he can't do all 5, and manually changes the schedule, and manually spreads out the 5 orders. The buyers will recieve rescheduling notifications, but not until the scheduler does the manual rescheduling.
You could call this "Infinite Scheduling", but that only means the same thing as Infinite Planning.

But, SAP has "Capacity Leveling". What that means is you run another program after MRP (CM27 and CM28), which can be run in batch mode overnight. (There is a ton of configuration and thinking that will be required to do this!). The capacity leveling program will recognize the constrant at the work center level, and fill up the first day, then re-schedule the next
order to the next available capacity, then the next order searches for available capacity, and so on. This is called "Finite Scheduling". The problem with this is the opposite of Infinite Planning, which is it doesn't take Material availablity into consideration! The system will re-schedule a production order without thinking about whether the materials will be available
or not.

Finite Planning does Finite Scheduling at the same time. If there is no capacity available on the desired date, the system looks for when capacity IS available. Then it stops to see if Materials will also be available (usually based on the lead-time for those components). If there is a material problem, then the system figures out when the materials WILL be available, and then
checks to see if capacity is available on THAT day, and if so, it blocks off capacity, and allocates the materials for that day.

Work Scheduling View in Material Master

What is the importance of work scheduling view in material master and the standard values in Routing?

If I am maintaining Lot size dependent information such as set time, Interoperation time, Processing time in work scheduling view in material master and also Total in-house production time in MRP view under scheduling tab, what will effect on the system?

Means how will the system behave in this scenario?

In house production time in MRP2 view, specifies the time in workdays needed to produce the material in-house. In-house production time is independent of the order quantity. The system requires the in-house production time to determine the planned dates for planned orders in materials planning.

You can define work scheduling times in the material master record in one of two ways:

-Either you enter the in-house production time. If required, you can get the system to update this value from the routing.

-Or you enter the setup, teardown, processing, and interoperation times. If you maintain these values, the system determines the in-house production time on the basis of lot size.

What is the basic fundamental of "Independent lot size" and "Dependent lot size" in work scheduling view of a material master. I am jumbling a lot between this two to understand the basic requirement of my client.

Second thing is that you are saying that - You can define work scheduling times in the material master record in one of two ways:
-Either you enter the in-house production time. If required, you can get the system to update this value from the routing.
-Or you enter the setup, teardown, processing, and interoperation times.
But how the system update this first option.

I mean to say , is there any setting in configuration so that the system will update workscheduling time values from the routings?

You need scheduling data for 2 types of orders, planned orders and production orders.

And you can have the scheduling data in 3 ways:

1. Lot size independent in-house production time, in material master, MRP2 view. ex: if in house production time is 2 days, it will schedule the order for 2 days, and it doesn't matter if the order size is 1 or 1000, they are both produced in 2 days. (I never met any case that fits this situation)

2. Lot size dependent in-house production time, in material master, Workscheduling view. ex: if you have 5 day setup time, and 1 day production time for lot size of 10, then your order will be scheduled according to the order size. if your order is for 10, then your total production time will be 5 day + 1 day x 10 / 10, which is 6 days. If your order is for 100, then your total production time will be 5 day + 1 day x 100 / 10, which is 15 days. 5 day setup time will not change when the order quantity changes, because you make the setup once at the beginning of the production, and use the same setup during whole production.

3. Lot size dependent in-house production time, in routing. The same calculation of above will be used for this.

So, which of these data is used for the 2 order types?

For the planned orders, for default, system uses the times in number 2 above. If that data is not entered, system will use the time in number 1 above. If you want the system to use the routing data, then you should use lead-time scheduling parameter in MRP run, then system will use data in number 3 above.

(The idea behind this is, MRP run always takes long time, and if you want it to use routing data, that will also increase this run time. Therefore, you can use routing but take results after long MRP run time, or you can use approximate times but take the results after short MRP run. This was very crucial before, because at those times hardware technology was not enough to process too much data in short time, when MRP run was taking days and days. But now is not that crucial, that's my personal opinion. As I said before, you can use routing data but take results after long MRP run time, or you can use approximate times but take the results after short MRP run, however, there's one other way which is a combination of these two: You can use the system to update the data in number 2 using the data in number 3, which is called the update of material master from routing. In that case, the approximate production times in material master will be as close as possible to the actual production times. In that case, not only MRP run will not take long time, but also we will get much better results.)

For the production orders, always the routing data is used for scheduling.

Now, I am cleared that what is independent and dependent lot size. but still there is one confusion in my mind that where did we mentioned this lot size i.e 10,100 as per your example in case 2.
Secondly, I didnt understand your second last sentence (i.e.the approximate production times in material master will be as close as possible to the actual production times). Can you please clear me this sentence with suitable example.

You enter the lot size on the Work scheduling view of material master, for the lot size dependent times, for my example you enter 10 as lot size.

And the approximation is like this: In the material master, you enter the production times as DAYS, but in the routing you can use MINUTES, even seconds. Therefore the most detailed and accurate production times can be entered in routing, in material master you can enter only days, which will be the approximate value.

If your routing is, for lot size of 10, setup time is 3 hours and production time is 50 minutes, when you update the material master from routing, system will write 3/24 days for the setup time, and 50/1440 minutes for the production time, because it has to convert it to days.

But still I dont understand that where I have to mentioned that lot size 10 or 100?
And second thing is that, If I have to use routing data for planned order what should I have to do? Shall I have to mentioned lead time scheduling in MD02?

You enter lot size in material master, on workscheduling view.

and yes, you have to mention on md02 screen that you want lead-time scheduling.

You mean to say I have to enter that 10 or 100 in base quantity of work scheduling view of material master?

Yes.

Scheduling-2

Schedule Margin Key in Production Scheduling

I want to know impact of schedule margine key in production scheduling in following changes in mateial master
1) if I have schedule key where all floats are zero but I enter in-house prodution time as e.g. 7 days .
2) if I have key where floats before prodution is 5 days and same values in next floats and in house production time as 1 day.
All above with MTO what is impact of above cases in scheduling.

While "Basic Scheduling" in MRP... Scheduling margin key is not considered. It takes the "In house production" days for fixing up the start date. This is only exact to "days".

Lead Time scheduling is carried out on request from the scope of MRP. Target dates are calculated from routing and Capacity requirement calculations are also done. The calculations are exact to the seconds (time).

SCHEDULING MARGIN KEY takes effect only for Lead Time Scheduling. For this you have to configure for "scheduling horizon" to limit the period for which lead time scheduling and capacity planning should be carried out. scheduling horizon is the period in working days. If a planned order has its basic start date within this period in future, lead time scheduling is carried out using the selected routing. The production times are calculated from the float times of the scheduling margin key in the material master record and the time from the individual operations. If the planned order has its basic start date further in the future than this scheduling horizon, the basic dates are calculated from the in-house production times in the material master and are transferred to the production times.

Could you explain what's function of opening period in Sched Margin key.

Opening period is like a "release window". The length of the opening period is the window of opportunity a planner has to convert the planned order to a purchase req.

For example - Component A has a lead time of 14 days and opening period of 5 days. Requirement on 12-22-03

Opening Date - 12-01-03
Start Date - 12-08-03
Finish Date - 12-22-03

Now the planner can convert the order starting Dec. 1st, instead of Dec. 8. It basically is a buffer in the lead time to get things on order a little sooner than needed.

What's the function for Plan order convert to production order?

As your example,
Requirement on 12-22-03

Opening Date - 12-01-03
Start Date - 12-08-03
Finish Date - 12-22-03

But I can convert plan order to production before 12-01-03 at random, so I wonder what is the opening period real function? it looks useless to restrict when to convert plan order to production order.

CO41 and MD15 are used for the conversion process. Here you enter the opening dates you wish to convert. Of course the opening period will not stop you from converting planned orders - hopefully your planner is not randomly converting orders or you have much bigger issues!!!!

The opening period is basically just to get the planned order to show up on the CO41 or MD15 lists in case you wish to convert it sooner than the lead time suggests.

Your answer make me clear to understand the opening period.

BTW,could you explain the release key ,float after production and float before production parameter in SchedMargin key?

I know the parameter affection in production,but I am not sure why to define how many days in each parameter.

for example, release key defined for 10 workdays,but you can release production order out of the release period randomly.any way to stop release out of the release period?

For example - Component A has a lead time of 14 days and opening period of 5 days. Requirement on 12-22-03
Opening Date - 12-01-03 ???
Start Date - 12-08-03 (from requirement date - lead time ?)
Finish Date - 12-22-03 (from requirement date ?)
Why Openning date = 12/01/2003 how system calculate , Could you please explain to me..

I know that when we run MRP system will check if the opening date is out of open period system will generate Plan order instead of PR .

The times in the sch. margin key are in workdays. That's how it gets the dates. The component I was describing originally would have been a purchased part, where lead time is in calendar days.

The order start date and the order finish date form the framework within which a production order is to be executed. Since malfunctions and disturbances in the production process can never be fully prevented, the system uses particular floats in a production order. The system takes into account so-called "before and after production floats" when scheduling an order.

The float before production is a start float. It has two functions:

It can compensate for delays in the staging of the material components.
If there is a capacity bottleneck at the work centers involved, the production dates can be moved forward in the future. In this way it serves as a float for capacity leveling.
The float after production is a finish float. It is used to compensate for unexpected disturbances in the production process, so that they do not delay the scheduled finish date.

The floats before and after production are defined for each material using a scheduling margin key. This scheduling margin key is automatically transferred from the material master when an order is created. However, you can change the times in the order.

The system calculates the scheduled start of the order by adding the float before production to the order start date. It calculates the scheduled finish of the order by subtracting the float after production from the order finish date.

The system deducts the number of days defined in the release period from the scheduled start of the order and thus determines the scheduled release date of the order. This date can be used for collective release.

Scheduling-1

Rescheduling date does not take into account the GR Processing Time

If you look at MD04, the rescheduling date is based on the Stocks Requirement date.

It does not take into account the parameters in Procurement and Scheduling in the Material Master.

In the net requirements calculation, the system checks whether warehouse stock or firmed receipts are available to cover requirements. If a material shortage exists, the system usually creates a new procurement proposal.

The rescheduling check is used to change the dates of already existing firmed receipts not planned on the same day as the requirement to suit the requirement date.

For this purpose, the system displays the appropriate exception messages with rescheduling proposals for these firmed receipts to be processed by the MRP controller.

You defined the rescheduling parameters in Customizing for MRP.

An important parameters is the rescheduling horizon period to be included.

1. OPPQ per plant to Carry out overall maintenance of plant parameters.

2. OPPR per MRP group to Carry out overall maintenance of MRP groups.

You can also define tolerance values for the creation of exception messages.

These values define a time period in which no exception message is to be created, despite the fact that a rescheduling proposal may exist.

The MRP controller can thus avoid a situation where too many exception messages are created if a certain buffer has already been planned for scheduling basis dates.

Rescheduling Exception Proposal

Bring process forward (reschedule in)

Within this rescheduling horizon, the net requirements calculation checks whether, after a requirement, a firmed receipt exists, which can be used to cover this requirement. Then the system displays a rescheduling date as well as the exception message Bring process forward for this receipt. The net requirements calculation then uses this receipt and the
system will only create another procurement proposal if the receipt quantity is not sufficient to cover the complete requirement. Several firmed receipts can be used to cover one requirement.

The rescheduling horizon is always calculated from the MRP date.

Postpone process (reschedule out), or cancel process

The net requirements calculation checks over the complete time axis whether availability could still be guaranteed without the receipt in question. If this is the case, the system checks whether the receipt planned here could be used to cover a future requirement. If the system can find such a requirement, it then displays a rescheduling date as well as the exception message Postpone process for this receipt.

If the system finds no future requirement, for which the receipt is required, the system displays the exception message Cancel process.

TABLE-3

Table of the Order Production Operation

Which is the table of the order production operation details? I need to get the activities for production order :
Setup, Labor, Machine, Confirmed and to confirm.
I can see look at this in CO02 / Operation Overview (f5) / Operation Detalis / Qty-Activities

That is probably the hardest information to piece together, I used 5 tables with multiple joins to get User Fields for operations in a production order. Maybe you can use something simular.

AFKO - this is for your basic production header info - order number, basic finish date etc

S022 - this is for your operation header details - operation number, Work centre etc if you are only after the header details such as setup time and execution time, you can probably stop here without going to AFVC or AUFV (you definitely need AUFK if you want order status)

AUFK - this is for your order master data - Order released flag, order complete flag, technically complete date, you'll need this to filter out closed orders

AFVC - this is to link to the detail table - however I used the control key field in it so I would know whether it was a MILE stone or GPP1 for confirmation's sake

AUFV - this is the user field table - you may want to replace this with whatever detail you are after

Delete all the automatic joins:

AFKO -> AUFK on:
AUFNR -> AUFNR

AFKO -> S022 on:
AUFNR -> AUFNR
PLNBEZ -> MATNR

AFKO -> AFVC on:
AUFPL -> AUFPL

S022 -> AFVC on:
WERKS -> WERKS
PLNFL -> PLNFL
VORNR -> VORNR

The join below is for user fields in operation detail, you will have to find your own relevant table, but I assume the two key fields will be the same??

AFVC -> AFVU on:
AUFPL -> AUFPL - Routing number of operations in the order APLZL -> APLZL - General Counter for order
