As per my understanding, the moment we create a material using MM01, a planning file entry is made for the same by the system. But for a particular plant i find a lot of materials not having planning file entry & hence they are not a part of MRP runs.
May i know what might be the reason that so many materials have not created a planning file entry? Is there anyway that i can know for a given plant which materials have not created a planning file entry?
(Note - These materials were created a long time ago)
Hope my question is clear, await inputs.
