Dear colleagues,
We have a multi-level production process, repetitive manufacturing, PP-REM, up to 6 levels of BOMs.
Finished and semi-finished goods can be produced on alternative resources and can have different BOMs.
Alternative modes are maintained as alternative sequences in a routing (CA01).
Different production versions(PDS) are created for different BOMs.
We need to create a feasible multi-level production plan which includes:
Could you please give me an example of heuristics to be used in the planning run /SAPAPO/CDPSB0 ?
Thank you in advance for your help.
Hi,
Here are some options you can check if it works
1. Use Stable forward scheduling heuristics post infinite production planning run. So steps will look like as below
1. Low Level code
2. SAP_MRP_001
3 Stable forward scheduling heuristics
Problem with above approch is not sure whether it will consider alternative resources or not
Second option is
1. low level code
2. SAP_MRP_001
3. PPDS Optimizer
Third option is
1. If only semifished and finished level(two levels) are having capacity constraints then
1. Low level code
2. SAP_MRP_001
3. Bottom up Heuristics till semifinshed product level
4. Reschedule function at semifinished product level with find slot scheduling and scheduling direction forward
5. Bottom up to correct schedule at finished product level
6 Reschedule function at finished product level with find slot and scheduling direction forward
