Production Scheduling capacity problem

[Former Member]

Dear All,

I am using Forward Scheduling Type in my Production Order and I am having the following problem:

The Work Center Capacity is defined with Capacity Category 002 - Person

I have create two Production Orders 10001 and 10002. Both are using Work Center ABC. We first create Production Order 10001 with the Basic Start Date as 2010-10-05 and the Basic Finish Date is 2010-10-07. In Transaction Code CM01 we can see the capacity requirement there.

Next we create the second Production Order 10002 and we enter the Basic Start Date as 2010-10-05 again. The SAP system carried out scheduling. The Basic Start Date is displayed as 2010-10-05 and Basic End Date is displayed as 2010-10-07 again after the scheduling. Meaning the two Production Orders have the same Basic Start Date and Basic End Date.

This is incorrect as the first Production Order 10001 should have acquired the capacity already and the Basic Start Date for the second Production Order 10002 should be on 2010-10-08.

Have anyone come across this and know the solution?

Many Thanks.

Dear

You have created two orders in same start and finish date. When you check in CM01, system will show capacity overload on that day based on available capacity. Thats why in SAP R/3 they have given the option of capacity levelling. Use the t.code CM21 to dispatch the operation of one order to another day.

Dear Ganesh,

Do you mean after I have create the two orders, I have to go to Order dispatch in order to reschedule the orders again?

Thanks

Yes.

Normally whenever you created the production order, first you need to go to t.code CM01 and check the capacity. If it shows on red colour, it means overload occur. So next step you have to go to CM21 transaction for that order do the dispatching of capacity.

Hi Ganesh,

Sorry I have got one more question, I found CM22 also can do the dispatch of Production Order. When we do dispatching, does the system automatically changes the Basic Start Date and Basic Finish Date of the Production Orders in case the capacity requirement is unavailable.

Thanks

I suggest gp to t.code CM21 and select your production order and dispatche the operation manually. Then you will get the pop-up screen, there you can choose the date and work center as you want.

Dear Jamison,

Yes

This is Std SAP R/3 Behavior

In R/3 system will only check material availability not capacity

In APO system this is possible

You need to manually do capacity leveling in R/3
