SAP Message QS372 - Inspection method &1 for plant &2 cannot be saved

Diagnosis
Inspection method &v1& in plant &v2& cannot be saved because of adifference in versions.
The system tried to replace one or more versions of an inspectionmethod using data records with the same key. However, not all theinspection method versions can be replaced or deleted, since they havea usage decision indicator. This error can occur, for example, duringdistribution with ALE.
Example
Versions 1, 2, and 3 of an inspection method should be saved.
Versions 1, 2, 3, and 4 already exist for this inspection method.Version 4 is used and has a usage indicator.
When you overwrite the "old" inspection method with the new one, youmust delete the "old" version 4 (to avoid inconsistencies in thedatabase). However, this is not possible because this version is stillin use. As a results, the operation cannot be performed.

System Response
The operation is canceled; the inspection method (with all versions)cannot be saved.

Procedure
