Diagnosis
The current assignments do not form an uninterrupted series. Undercertain circumstances, this is not permitted. In the following cases,gaps are not permitted.

• If multiple assignment is activated and a main assignment is maintained,
this assignment must be defined without gaps to 31.12.9999.

• If the method VALIDITY_PERIOD_CHECK of the BAdI
BADI_MATGRP_HIER_CHK was used to forbid gaps, all assignmentsmust be (including the secondary assignments when multiple assignment isactivated) without gaps.

• If the method ARTICLE_MANDATORY_CHECK of the BAdI
BADI_MATGRP_HIER_CHK was used to activate a mandatory assignment,there must be at least one assignment with uninterrupted validity to31.12.9999.
When multiple assignment is valid, the check for gaps is run for allassignments in a category. When multiple assignment is not valid, thecheck for gaps is run for all assignments in the entire hierarchy.
