Hi ,
In material master -
- In MRP4 -maintain component scrap% .-- In your case (since 'A' is R/M)
- If material is assembly, then the same can be maintained in MRP1 - as Assembly scrap%.
When u find few damaged RMs & want to capture costing details as well as person, return it to Cost center by mb1a -202 , where it will ask u to maintain Cost center, G/L , Receiver & storage location details .
Pls. revert if useful.
Regards,
Milind
