• What is the cause and solution for SAP error message CM_SUB_MLI019 - Inheritance relationship cannot be deactivated ?

  The SAP error message CM_SUB_MLI019, which states "Inheritance relationship cannot be deactivated," typically occurs in the context of managing inheritance relationships in SAP Master Data Management (MDM) or similar modules where data inheritance is utilized.
  Cause:
  This error usually arises when you attempt to deactivate an inheritance relationship that is currently in use or is required by the system. Inheritance relationships are often used to define how certain attributes or properties are inherited from a parent object to a child object. If the system detects that the relationship is still active or necessary for data integrity, it will prevent deactivation.
  Possible Causes:

  Configuration Settings: Certain configuration settings in the system may enforce the requirement for the inheritance relationship to remain active.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Dependencies: Review the objects or data that depend on the inheritance relationship. Ensure that there are no active references that would be affected by deactivating the relationship.
  
  
  Review Configuration: Check the configuration settings related to inheritance in your SAP system. Ensure that there are no settings that enforce the relationship's necessity.
  
  
  Data Cleanup: If there are any child objects that are still using the inherited properties, consider updating or removing those dependencies before attempting to deactivate the relationship.
  
  
  Consult Documentation: Refer to SAP documentation or help resources specific to your version of SAP for detailed guidance on managing inheritance relationships.
  
  
  Seek Support: If the issue persists, consider reaching out to your SAP support team or consulting with an SAP expert who can provide insights based on your specific system configuration and usage.
