  The SAP error message CACSCUST204 typically indicates an issue related to the configuration of package specialization in the SAP system. This error occurs when there is an inconsistency in the way that lower packages are defined or specialized in relation to a higher package.
  Cause:
  The error message CACSCUST204 is triggered when:
  
  There is an entry in a lower package that is trying to specialize a key that is already defined in a higher package.
