24.1.3.
Setup:
Multi-level product structure looks like this:
- FG PW-PSM-000 is lot tracked, weighted average, cost per lot.
- For all subassemblies Negative On Hand Allowed = YES (no lot tracking).
- Safety Stock = 0 for all parts.
- All components have zero on-hand quantity and zero supply/demand.
- Lower subassemblies assigned default picking locations.
- Customer order for 2000 tons of FG PW-PSM-000 is the only demand relevant for this structure.
- Looking only at the IPAP situation for the manufactured parts through the following steps.
Run MRP for customer order line (selective MRP). IPAP results:
Report production receipt for 2100 tons (overproduction) of PW-PSM-001, driving the on-hand of level 1 negative. IPAP results:
Run Selective MRP for low level 1. IPAP results:
Why did level 2 demand and supply remain at 2000? Expected it to see the level 1 supply of 2100 as its ‘new’ net requirement.
