Hello,
The mixed material requirements planning indicator in the material master is set to '1' = 'Subassembly planning'.
Normally whenever we use planning at assembly level strategy FERT or higher level should consume the requirement this is possible if u use mixed indicator 1.
496480 - Planning consumption during sub-assembly planning
Please share screen shot of planning strategy defined in OPPS.
What is the PIR Consumption Indicator?
Best Regards,
