thank you Mariano,
I was off from group form long time, so missed the Rules of engagements , However after searching lot I am unable to find business answer.
We have implemented R3 in 2004 now migrated in ECC
Implemented APO last year, we are using SNP and DP fully.
Our industry goes through lot of SKUs changes, where new SKU code comes and BOM changes very fast example packing change, Promotions, recipe change, weight changes of SKUs.
Infact many cases production BOM is not created on time due to, business do not have full visibility. We want to plan only critical items( packaging materials) in MRP as of now . We are creating engineering BOM in advance for critical items in advance with BOM having only critical components.
We are trying for MRP run in APO since facing lot of issues of Data Hygiene in ECC, so I am more advocating MRP run in APO where we can control transaction data by manual upload.Biggest challenge in APO we are finding , switching on/ off required PPMs for MRP run. Some of PPM are created to take care of SNP line balancing of packing lines which to be deactivated.
In my understanding if you want to plan all material , try in ECC . if only critical material then in APO.
But our top Management got feedback from business consultants in FMCGs it should be tried in ECC. But I find much challenge in our ECC system than APO.
This more business question, request consultants share their experience base on real implementations done in FMCGs across the world.
