• What is the cause and solution for SAP error message USMD7021 - Rule set &1 will be disabled when model &2 is activated ?

  The SAP error message USMD7021 indicates that a specific rule set (denoted as &1) will be disabled when a particular model (denoted as &2) is activated. This message typically arises in the context of SAP Master Data Governance (MDG) when there are conflicts or issues with the configuration of rule sets and models.
  Cause:
  
  Conflicting Rule Sets: The rule set you are trying to activate may have conflicts with the model you are working with. This can happen if the rule set is not compatible with the model's configuration or if it is designed for a different type of data governance scenario.
  Inactive Rule Set: The rule set may not be properly configured or may be inactive, leading to its automatic disabling when the model is activated.
  Dependencies: There may be dependencies between different rule sets and models that are not being met, causing the system to disable the rule set to maintain data integrity.
  
  Solution:
  
  Review Rule Set Configuration: Check the configuration of the rule set (identified as &1) to ensure it is compatible with the model (identified as &2). Make sure that the rule set is correctly defined and activated.
  Check Dependencies: Investigate any dependencies between the rule set and the model. Ensure that all necessary prerequisites are met for both the rule set and the model.
  Activate Rule Set: If the rule set is inactive, try to activate it manually before activating the model. This can often resolve the issue.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the rule set and model in question. There may be known issues or additional configuration steps required.
  Testing: After making changes, test the activation process again to see if the error persists.
