Storage location in CJ20N

Good Evening PS Gurus,

User is adding material to project builder & changing the Storage location (A) in the project & choose reservation for WBS. Upon MRP run in MD04 for that material storage location is wrong (B) (meaning it’s not the same storage location (A) which was entered in project builder, but it’s coming from Storage loc. for EP (B) under procurement in MRP 2 tab under material master)

Is there any way we can bring the same Storage location (A) as in CJ20N after MRP run in MD04 screen.

Kindly do me the needful.

Thanks & Regards

MM
