Multilevel Bottom up Heuristic

[Former Member]

Dear SCM techies,

I have a situation where I am having my demand on FG, I am running SAP_MRP_002 (Plan comp immdiatly) to explode the BOM and get the planned orders for SFG and Preq for raw materials.

All this happens in infinite mode.

Now I want to reschedule this finitely w.r.t raw material availability.

So I created one Heuristic Bottom up from ZSAP_MRP_001 which internally uses heuristic SAP_PP_009

My expectations system schedule planned orders of SFG as per RM availabilty, and FG should be scheduled when SFG is available.but thats not happening..

Steps I am following:

1. Create planned orders of FG,SFG by SAP_MRP_002

2. Fix pegging run to link recipts and demand

3. Rescheduling by bottom up heuristic

But results are not upto d mark...

Requesting you guys to know share the knowlegde to attain the required situation.

Regards,

Pankaj

Hi,

we have customized such a MRP heuristic for bottom up like this:

Algorithm: /sapapo/heu_mrp_planning

Other heuristic: ZSAP_PP_009

Reuse Mode: use suitable receipt elements

Checkbox marked: Create planning file entry for components

And now an important setting:

Checkbox marked: sort low-level codes in decending order

ZSAP_PP_009 differs from standard SAP_PP_009 in these parameters:

Basic Settings:

Date Shift Direction: Dates Can Only Be Shifted Into The Future

Strategy:

Shed.Mode: Search for Bucket with Free Capacity

Strategy for dep.Obj.:

Consider max intervals and plannning-related minimum interval -> both boxes unmarked

Kind regards,

Christian

Hello,

Thanks for reply. I am using the same settings except

Shed.Mode: Search for Bucket with Free Capacity, I am using Infinite mode, I tried with above setting but not getting the appropiate results.
