• What is the cause and solution for SAP error message USMD2086 - Data model cannot be changed; change request type &1 already in use ?

  The SAP error message USMD2086 indicates that a data model cannot be changed because a change request of a specific type (denoted by &1) is already in use. This typically occurs in the context of SAP Master Data Governance (MDG) when you attempt to modify a data model that is currently locked or being processed in a change request.
  Cause:
  
  Active Change Request: The primary cause of this error is that there is an active change request of the specified type that is currently being processed. This means that the data model is locked for changes until the change request is either completed or released.
  Locking Mechanism: SAP uses a locking mechanism to prevent concurrent changes that could lead to data inconsistencies. If a change request is open, the system will not allow modifications to the data model.
  
  Solution:
  
  
  Check Active Change Requests: 
  
  Go to the relevant transaction (e.g., MDG_MAT, MDG_CUST) and check for any active change requests of the type indicated by &1 in the error message.
  You can use transaction codes like SWI1 (Work Item Selection) or SWI2_FREQ (Work Items by Frequency) to find active change requests.
  
  
  
  Complete or Release the Change Request:
  
  If you find an active change request that is blocking your changes, you can either complete it or release it, depending on your role and permissions.
  If you are not the owner of the change request, you may need to contact the person responsible for it to either complete or release it.
  
  
  
  Wait for the Change Request to be Processed: 
  
  If the change request is being processed by another user, you may need to wait until they finish their work.
  
  
  
  Check for Locks: 
  
  You can also check for any locks on the data model using transaction SM12 to see if there are any locks that need to be released.
  
  
  
  Consult Documentation: 
  
  Review the SAP documentation or help resources related to Master Data Governance for more specific guidance on handling change requests.
