Hi All,
When I convert a subcontracting SNP- PReq at Plant then it creates an SNP PReqRel at vendor keeping in account PDT (Planned Delivery Time) , Transportation Time and GR time at Plant.
The SNP Planned Order created at vendor is created on the basis of backward scheduling.
( i.e. SNP Planned Order Completion date = Delivery Date at the Plant - Transportation Time - GR time
e.g. SNP Planned Order Completion date( 10th Oct ) = Delivery Date at the Plant(17th Oct) - Transportation Time(4 days) - GR time ( 3 days)
Needless to say here -- SNP Planned Order finishes as per the time maintained in PPM/PDS for operation. ( e.g. say 4 days -- so it starts on 7th Oct).
The issue comes when I convert this SNP Preq at plant to PPDS PReq. The system schedules the order from current date or as soon as possible instead of doing backward scheduling. I checked the strategy profile in SPRO for SNP->PPDS conversion and in that strategy profile -- the direction for scheduling is forward.
As per me it should be backward or backward with reverse if I want the order to finish on 10th Oct as per example above.
This is bcoz between SNP and PPDS -- Transportation Time, GR time, PDT etc all remain same -- so I do not doubt the Master data.
Can you suggest some other pointer --- or only the direction of scheduling in the strategy in strategy profile for SNP->PPDS conversion -- the only probable reason ?
Thanks.
