• What is the cause and solution for SAP error message USMD2268 - Identical list component for dependent entity type &1 used more than once ?

  The SAP error message USMD2268 indicates that there is an issue with the configuration of a data model in SAP Master Data Governance (MDG). Specifically, it points out that an identical list component for a dependent entity type is being used more than once in the data model. This can lead to confusion in data processing and validation.
  Cause:
  The error typically arises from the following scenarios:
  
  Duplicate List Components: You have defined the same list component for a dependent entity type multiple times in the data model.

  Ensure that the remaining components are correctly configured and linked to the appropriate entity types.
  
  
  
  Validate the Model:
