• What is the cause and solution for SAP error message USMD1048 - Data model &1: Search help for (hierarchy) attribute &2 is not unique ?

  The SAP error message USMD1048 indicates that there is a problem with the uniqueness of a search help for a hierarchy attribute in a data model. This error typically arises in the context of SAP Master Data Governance (MDG) when you are trying to create or modify a data model, and it suggests that the search help defined for a specific attribute is not unique.
  Cause:
  The error occurs due to one of the following reasons:
  
  Non-Unique Search Help: The search help assigned to the hierarchy attribute is not unique, meaning that there are multiple entries in the search help that could match the input value.
  Incorrect Configuration: The configuration of the search help or the hierarchy attribute may not be set up correctly, leading to ambiguity in the search results.
  Data Model Issues: There may be issues with the data model itself, such as overlapping definitions or incorrect relationships between attributes.

  To resolve the USMD1048 error, you can take the following steps:
