A1 is a finished goods material. B1 is a component material. BoM has been maintained for material A1 with B1 as the component.
Planned independent requirement for material A1 is maintained in MD61 transaction.
Dependent requirement for material B1 has been generated for material B1 with A1 as MRP element when MD41 transaction has been executed for Material A1
Material A2 is created with reference to Material A1
Material B2 is created with reference to Material B1
BOM has been matained for material A2 with B2 as the component.
Planned independent requirement for material A2 is maintained in MD61 transaction.
When we have executed MD41 for A2 material, dependent requirements are not generated for Material B2 with A2 as MRP element.
Do we need to maintain any other settings after creating material master and BOM and before running MD41, in order to generate dependent requirements for componet material B2?
Check if when you created the master data of material A2 by copying from A1, the production versions of the reference material (A1) have been adopted to material A2.
Check if in MRP4 screen there is at least one production version. If there isn't, you have to create one and assign there the BOM and the routing of A2 material.
