• What is the cause and solution for SAP error message CM_SUB_MLI002 - Inheritance templates &1 and &2 have overlapping data areas ?

  The SAP error message CM_SUB_MLI002 indicates that there are overlapping data areas in the inheritance templates specified in the error message. This typically occurs in the context of Master Data Management (MDM) or when dealing with inheritance templates in SAP, where two templates are trying to define the same data area or attributes, leading to a conflict.
  Cause:
  
  
  Overlapping Data Areas: The error arises when two inheritance templates are defined in such a way that they cover the same data area or attributes. This can happen if:
  
  Both templates are trying to inherit from the same parent template or data area.
  There are conflicting definitions or attributes in the templates that overlap.
  
  
  
  Incorrect Configuration: The configuration of the inheritance templates may not have been set up correctly, leading to overlaps.
  
  
  Changes in Templates: If changes were made to one or both templates after they were created, it could lead to overlaps that were not present initially.
  
  
  Solution:
  
  
  Review Inheritance Templates: Check the definitions of the inheritance templates mentioned in the error message. Look for overlapping attributes or data areas. You may need to:
  
  Modify one of the templates to ensure that they do not overlap.
  Remove or adjust the conflicting attributes in one of the templates.
  
  
  
  Consolidate Templates: If the templates are meant to serve similar purposes, consider consolidating them into a single template to avoid overlaps.
  
  
  Check Parent Templates: If the inheritance templates are derived from parent templates, ensure that the parent templates do not have overlapping definitions that could propagate to the child templates.
  
  
  Testing: After making changes, test the templates to ensure that the error is resolved and that the intended functionality is preserved.
  
  
  Documentation: Document the changes made to the templates for future reference and to help prevent similar issues.
