A/c assignment category for material type
1) Can I fix a/c assignmnet category for a material type? For example, I want a/c assignment category K for NLAG materials. If while creating PO for a NLAG material, somebody forgets to enter A/c assignment category, it should give an error msg "A/c assignment category is manadatory for the material type"?
2) If Gr-based IV is not checked in ERS PO, then while running MRRL statement, what type of error should come and what will be the remedy at that stage?
