Capacity Leveling Heuristic in PPDS

485 Views

Guys -

I was going through some PPDS documentation and it says that up until APO 3.0 it was possible to use the MRP Heuristic(SAP_MRP_001 with finite MRP setting)for<b> finite planning</b>. So basically this heuristic is used for <b>both requirements and capacity planning</b> simultaneously. It also said that this is not a good approach and it is always better to follow the 2 step process of :

1) Planning Heuristic(infinite) something like the standard lots SAP_PP_002

2) Then do Capacity leveling through the capacity leveling heuristic.

I have 2 questions on this:

Q1) Is it true that its not possible to use 1 heuristic to for both materials and capacity planning anymore or we can still do it but not recommended as the results may be inaccurate?

Q2)I am looking at the Schedule Sequence SAP001 heuristic to do capacity leveling at the bottleneck resources. Is this the correct heuristic for capacity leveling?

Thanks a lot!
