P2M 202 ยท PLANNING DETERMINATION
What determines a planning result?
MRP behaviour is inherited from demand, stock, master data, and planning rules. Read the determination stack before treating a planned order, date, quantity, or sourcing decision as an isolated error.

Questions that determine the outcome
Material planning parameters
MRP type, lot size, safety stock, planning time fence, lead times, and procurement type influence supply quantity, date, and form.
Production model
BOM, routing, production version, work center, and validity decide the structure and execution model that supply inherits.
Supply boundary
Procurement type, special procurement, and source decisions determine whether MRP creates in-house supply or hands the need to P2P.
P2M SCENARIO
A proposal is dated too late
Trace requirement date, lead times, scheduling, firming, and selected production model before changing the proposal.
- Prove the requirement and stock position.
- Identify the exact input that created the date.
- Retest proposal and dependent requirements.
Use 303 for operational execution and 606 to diagnose a live failure.
