• What is the cause and solution for SAP error message USMD1014 - Data model &1: Data element of (hierarchy) attribute &2 is not unique ?

  The SAP error message USMD1014 indicates that there is an issue with the data model in the context of SAP Master Data Governance (MDG). Specifically, it points out that the data element of a hierarchy attribute is not unique, which can lead to inconsistencies or errors in the data model.
  Cause:
  The error typically arises due to one of the following reasons:
  
  Non-Unique Hierarchy Attributes: The hierarchy attribute specified in the error message is not unique across the data model. This means that there are multiple entries with the same value for that attribute, which violates the uniqueness constraint expected by the system.
  Incorrect Configuration: There may be a misconfiguration in the data model or hierarchy settings that leads to this issue.
  Data Integrity Issues: Existing data in the system may not adhere to the uniqueness requirement, causing the error when trying to validate or process the data model.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Hierarchy Attributes:
  
  Review the hierarchy attributes defined in your data model. Ensure that the attribute specified in the error message is set up correctly and is intended to be unique.
  
  
  
  Data Validation:
  
  Perform a data validation check to identify any duplicate values for the hierarchy attribute in question. You can use SQL queries or SAP tools to find duplicates in the relevant tables.
  
  
  
  Modify Data Model:
  
  If the hierarchy attribute is not supposed to be unique, consider modifying the data model to reflect the correct business logic. This may involve changing the attribute settings or redefining the hierarchy.
  
  
  
  Data Cleanup:
  
  If duplicates are found, you may need to clean up the data by either removing duplicates or consolidating them as per your business requirements.
  
  
  
  Reconfigure Data Model:
  
  If necessary, reconfigure the data model in SAP MDG to ensure that the hierarchy attributes are correctly defined and that the uniqueness constraint is respected.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on configuring hierarchy attributes and data models in MDG.
  
  
  
  Related Information:
