Example of a multi-level production run (finite scheduling)

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:

• raw materials planned delivery time
• workload of main and alternative resources (finite scheduling)
• removal of backlog

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.
