What are some benefits of planning with planned independent requirements for finished materials?

Planning withplanned independent requirements(PIRs) in SAP S/4HANA (entered via MD61) for finished materials offers benefits in a make-to-stock or forecast-driven environment:

Reduced delivery times(A): By planning PIRs in advance (e.g., strategy 10 or 40), production can start before sales orders arrive, ensuring finished goods are available in stock. This shortens the time between order receipt and delivery, improving customer service levels.

Reduced times for final assembly(B): In strategies like 40 (Planning with Final Assembly), PIRs trigger procurement and production of components early. When sales orders arrive, only final assembly is needed, reducing the overall lead time for completion.

Option to forecast planning for production resources(C) is a byproduct of capacity planning (e.g., CM01), not a direct benefit of PIRs—PIRs focus on material demand.Option to use make-to-order production(D) contradicts PIRs, which are for make-to-stock or forecast-based planning (e.g., strategies 10, 40), not MTO (e.g., strategy 20). This is per SAP’s demand management benefits.
