Please advise what is the difference between running MRP using MDBT versus using MD03 aside from one is Background run and the other is Online. I ask this question because we set-up Opening Period for MRP in SMK of Material Master and in MDBT, we use Create Purch Req as 2, but it generates PR even for those outside the Opening Period, but if you use MD03 and use the same parameter 2 for Create Purch. Req. for the item, it generated Planned Order (STPO) and not PR for those outside Opening Period.
Is there any other reason why in MDBT, PR is generated even for those outside Opening Period? Please help ..... Thanks in Advance.....
