Diagnosis
In Customizing for versioning, you specified that the validity periodsof versions of an object must not overlap. You have now created aversion with a validity period that would overlap with the validityperiod of another version. To prevent this overlap from occurring, thesystem has adjusted the validity period of the created/existing versionin line with the following rules:

• The valid-from date of a version is not changed.


• The valid-to date of a version is only brought forward. It is not
extended.
Example:
Version 1 of an object is valid from 01/01/2002 to 01/31/2002. Youcreate version 2 of the object, which is valid from 01/15/2002 to04/30/2002. The system then automatically reduces the validity ofversion 1 to the period 01/01/2002 to 01/14/2002.
