2-Stage Planning
Looking for pointers on how to model the following scenario in ASCP:
For simplicity, let's say we have 2 distribution centers (DC1 & DC2) and 1 factory (FAC) that supplies to these 2 distribution centers.
Demands are placed on DC1 & DC2, which are then sourced from the FAC. We need to do 2-stage planning process where the aggregated supply at FAC is smoothed before it is used to drive MRP for buy components.
I have tried to run an MPS for DC1, DC2 and FAC for make items only, smooth/firm the planned orders at FAC then attach this MPS to FAC org to drive MRP for buy components. However, when I do this, the demands placed at DC1 and DC2 are not visible in the MRP plan. I would like the supply-demand pegging information to be maintained across DC1, DC2 and FAC. Even when I attach the MPS plan to all the orgs DC1, DC2 and FAC, no pegging information is available.
