• What is the cause and solution for SAP error message USMD_MC_CONV_GOV002 - Field changes are ignored since key values are changed. ?

  The SAP error message USMD_MC_CONV_GOV002 indicates that field changes are being ignored because the key values of the data being processed have changed. This typically occurs in the context of Master Data Governance (MDG) when there are attempts to modify data that is linked to a key field (like a primary key) that has been altered.
  Cause:
  
  Key Field Change: The error arises when a key field (such as a unique identifier) is modified in a way that it no longer matches the original record. This could happen if you are trying to change a record's key value while also attempting to update other fields.
  Data Consistency: SAP enforces data consistency rules, and changing key fields can lead to inconsistencies in the data model, which is why the system prevents further changes to non-key fields.
  
  Solution:
  
  Review Key Changes: Check the changes being made to the key fields. If you need to change a key field, ensure that you are aware of the implications and that it is necessary for your business process.
  Separate Key Changes from Other Updates: If you need to change both key fields and other fields, consider separating these operations. First, update the key fields, save the changes, and then perform the updates on the other fields in a subsequent operation.
  Use the Correct Process: Ensure that you are following the correct process for updating master data in MDG. This may involve using specific transaction codes or workflows designed for this purpose.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on handling key field changes in MDG. This can provide insights into best practices and potential workarounds.
  
  Related Information:
  
  MDG Configuration: Understanding the configuration of your MDG system can help you identify how key fields are defined and managed.
  Data Model: Familiarize yourself with the data model in use, as this will help you understand the relationships between different fields and the implications of changing key values.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context or solutions.
  Support: If the issue persists, consider reaching out to SAP support or your internal SAP team for assistance, especially if this is impacting critical business processes.
