What causes this issue?

The current assignments do not form an uninterrupted series. Under
certain 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 <ZK>VALIDITY_PERIOD_CHECK</> of the BAdI
<ZK>BADI_MATGRP_HIER_CHK</> was used to forbid gaps, all assignments
must be (including the secondary assignments when multiple assignment is
activated) without gaps.
If the method <ZK>ARTICLE_MANDATORY_CHECK</> of the BAdI
<ZK>BADI_MATGRP_HIER_CHK</> was used to activate a mandatory assignment,
there must be at least one assignment with uninterrupted validity to
31.12.9999.
When multiple assignment is valid, the check for gaps is run for all
assignments in a category. When multiple assignment is not valid, the
check for gaps is run for all assignments in the entire hierarchy.

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_ARTICLE_SCREENS026: The definition of the validity intervals must be gap-free
  
  
  Cause:
  This error occurs when you define validity intervals (date ranges) for an article (material) or related master data in SAP, and there are gaps between these intervals. In other words, the system expects the validity periods to be continuous without any breaks or overlaps, but it has detected one or more gaps between the defined intervals.
  For example, if you have validity intervals like:
  
  01.01.2023 to 31.01.2023
  02.02.2023 to 28.02.2023
  
  There is a gap on 01.02.2023, which causes the error.
  
  Explanation:
  In SAP, certain master data objects (like articles in Retail or materials in MM) require validity intervals to be defined continuously to ensure consistent data processing and reporting. Gaps in validity intervals can lead to inconsistencies or undefined behavior in processes that rely on these intervals.
  
  
  Solution:
  
  
  Check Validity Intervals:
  
  Review the validity intervals defined for the article
