  The SAP error message MDG_MDF020 with the description "Fixed Values cannot be changed" typically occurs in the context of Master Data Governance (MDG) when you attempt to modify a fixed value in a data model that is not allowed to be changed. This is often related to fields that are defined as fixed values in the configuration of the data model.

  Data Model Configuration: The data model or the specific entity you are working with has been configured to restrict changes to certain fields.
  Authorization Issues: In some cases, the user may not have the necessary authorizations to make changes to certain fields, although this is less common for fixed values.
  
  Solution:
  
  Review Configuration: Check the configuration of the data model in the MDG application. Identify the field that is causing the error and confirm that it is indeed set as a fixed value. If changes are necessary, you may need to adjust the configuration, but this should be done with caution and typically requires administrative access.
  Consult Documentation: Refer to the SAP documentation or the configuration guide for your specific version of MDG to understand the implications of changing fixed values.
  Use Alternative Fields: If you need to capture different information, consider using alternative fields that are not fixed values or creating new fields if necessary.
  Contact Support: If you believe that the fixed value should be changeable or if you encounter this error unexpectedly, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
  
  Related Information:
