• What is the cause and solution for SAP error message USMD6079 - Data model &1: Create/change/delete master data has been started ?

  The SAP error message USMD6079 typically indicates that there is an ongoing process related to the creation, change, or deletion of master data in the context of the SAP Master Data Governance (MDG) application. This message is often encountered when a user attempts to perform an action on master data while another process is already in progress.
  Cause:
  
  Concurrent Processes: The error usually arises when multiple users or processes are trying to modify the same master data object simultaneously. SAP MDG locks the data to ensure data integrity and consistency.
  Long-Running Transactions: If a previous transaction is taking longer than expected, it may prevent other transactions from proceeding.
  System Configuration: There may be specific configurations or settings in the MDG system that are causing this behavior.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for the ongoing process to complete. Once the lock is released, you can attempt your action again.
  Check Active Processes: Use transaction codes like SM12 (to check for locks) or SM21 (to view system logs) to identify if there are any active processes that are holding locks on the master data.
  Identify the User/Process: If you find that a specific user or process is holding the lock, you may need to coordinate with that user to determine when they will complete their transaction.
  System Monitoring: Implement monitoring tools or alerts to notify administrators of long-running transactions that may lead to such locks.
  Review Configuration: If this issue occurs frequently, it may be worth reviewing the configuration of your MDG system to ensure it is optimized for your business processes.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 (to view and manage locks), SM21 (to check system logs), and ST22 (to analyze dumps).
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Documentation: Review the SAP MDG documentation for best practices on managing master data and understanding the locking mechanisms in place.
  
  If the problem persists after trying the above solutions, it may be necessary to involve your SAP Basis team or SAP support for further investigation.
