MRP is not working for one material
I've run MRP without problems, but now I have a problem with one material. It is strange because if I copy that material with MM01, create the BOM and the run the MRP, everything works fine with the new material, but not with the old one.
Any idea why it could be not working, while the copy works perfectly?

It has probably no planning file entry.
This happens from time to time, can especially happen for materials after a migration.
There are several OSS notes about that.
Just check in MD21 is you hav a planning file entry, if no create one individually with MD21 or en mass with MDAB.
