Diagnosis
A check has shown that the validity intervals of the object and of thedetail &V1& differ. As the detail can also be valid for anotherversion, you cannot delete the object.

Procedure
If the detail &V1& is not required in another version of the object,delete &V1& and all other detail objects that have a different validityinterval.
If &V1& is to be used in another version of the object, set the end ofvalidity for the object such that &V1& is also affected. You can thendelete the object.
