Could you please confirm if a SAP APO DRP/Heuristic (Location) refers to low level codes if they are available before DRP run?
Basically im trying to implement Multi location heuristic by excluding Plants and Co packers/Sub contractors based on low level codes. There are several categories of products but to start with we are trying to test and see only for 2 categories. We need to run the 'Whole Model' to generate low level codes. Then for DRP/Location Heuristic run we create selection profiles so that only the chosen 2 categories of products are calculated by referring to low level codes.
The main concern here is for categories where low level codes exist DRP will use it for planning sequence but for categories which are NOT chosen in the selection profile will the system still refer to MATMOD table/Low level codes for planning sequence? Does the system automatically refer to low level codes even if we don't include the skus/categories in selection profile?
Would really appreciate if you could share your experience.
