Rescheduling of Process Orders after Partial Confimation (Oper. Duration)

[Former Member]

Hi experts,

have following problem, question.

Have a process order 10000 PC, one operation/phase - processing time (duration) 100H.

Now following scenario:

(1) posting first partial confirmation of the phase 1 PC and reschedule order since would like to know the new operation end. Order/operation end does not change so much since 1 PC does not consume the duration so much.

(2) posting second partial confirmation 1 PC again, after 2 hours (so we produce slower than expected, normally should be 200 PC to be confirmed now) and would expect that the order/operation duration would again will not change much after rescheduling since only 2 PC were produced.

But what happens is, the operation duration is reduced by 2 hrs after second confirmation is posted when order is rescheduled. Is this standard sap functionality that operation duration is reduced not by confirmed partial quantities (partial times) but by time interval passed between last partial confirmation and second last confirmation?

The production Resource formula for processing time is nothing special, just using operation qty / base qty * standard value for machine time.

Seems to me this formula works only when order is being created and scheduled. After that some other logic is used...

How can I achieve what I described above, that after operation rescheduling the operation is reduced by time equivalent posted in partial confirmations?

Thanks for your help.

Kind regards,

Juraj

Hello,

The calculation of the remaining duration of the partially confirmed operations via the remaining quantity is not a requirement which is process order specific and corresponds to the processing of the discrete manufacturing as known from PP. For this reason, it cannot be supported for process orders in the standard system.

Please refer Special development note  307585 - Process order scheduling with partial confirmation

Implement correction instruction from the note for process orders with the modification described in the correction instruction

Hello R.Brahmankar,

think this is exactly what I was looking for. Will implement the note and check. Thanks!

Hello

I suggest you to take a look on note 1789680, which explains the capacity reduction proportional to service.

Hello Caetano,

I know the note but could not get it working.

I enhanced the resource with capacity category 001 Machine since reduction to service does not work for category 008 which we use now. Used the category 001 also as a base for scheduling on resource scheduling tab.

Also assigned record type group "2 processing" in costing view but it does not work.

It is doing the job for remaining capacity requirements for operation but not for operation sprocessing time. If I reschedule it is still reducing by time interval passed between last partial confirmation and second last confirmation.

Running out of ideas to be honest.

Thanks.

anyone any more ideas?
