Shortage/Surplus of material stock level due to differences in Planned/Production Order Start and Finish date

Normally, the planned order determined the date from Material Master. The Planned Order created by the MRP reads the production capacity requirement from Material Master. (MM03 – Work Scheduling – Lot size dependent in-house production time). When you convert the planned order to a production order, SAP determined the date from Routing.

User Requirements:- Planned and Production Order should read the requirement from routing.

Solutions:-
Run MRP Scheduling -> 2 – Lead time scheduling and capacity planning

Transaction OPA9 (Sel. Profile - SAPA010) - Change configuration for Capacity Planning to read Production Order. Untick the Planned orders under the Order categories.
