• What is the cause and solution for SAP error message USMD1550 - Model &1, entity type &2: Source fields for texts must not be entered ?

  The SAP error message USMD1550 typically occurs in the context of SAP Master Data Governance (MDG) when you are trying to create or modify a data model. This specific error indicates that there is an issue with the configuration of source fields for text entities in your data model.
  Cause:
  The error message "Source fields for texts must not be entered" suggests that you have defined source fields for a text entity in a way that is not allowed.
