MMAM The material is used in BOMs or is a BOM

[marcoantonio_romerosanche]

Hi

We changed more than 500 materials from KAUF to VERP material type.

But exist 3 KAUF that I got message:

"The material is used in BOMs or is a BOM However, the new material type is not defined for BOMs"

We already check the following:

1.- Material are not a BOM (no production, engeenering, etc)

2.- Materials have not stocks (unrestricted, quality, blocked)

3.- not open Inspection lots

My mayor concern is why ony 3 of 500 materials that have same parameters cannot be changed?

How did you check whether the material is used or is a bom? I recommend to look with SE16 into MAST and STPO tables.

Further check 2513644 - MMAM material type change not working because of BOM

Missing Customizing as Jürgen comment.

After doing a debug, was discovered a combination missing in the table.

F|DOCM|VERP|+

Entry was added and can be changed the material type.
