  The SAP error message SZDM_LOCK821 typically indicates that there is an issue with switching the external visibility of a specific object or entity in the SAP system. This error often arises in the context of data management or when dealing with master data, particularly in the SAP Data Management or SAP Master Data Governance (MDG) environments.
  Cause:
  The error message SZDM_LOCK821 can be caused by several factors, including:
  
  Locking Issues: The object you are trying to modify may be locked by another user or process. This can happen if another transaction is currently using the object.
  Authorization Problems: The user may not have the necessary authorizations to change the visibility settings of the object.
  Data Consistency Issues: There may be inconsistencies in the data that prevent the visibility from being switched.
  Technical Errors: There could be underlying technical issues in the SAP system, such as database problems or configuration errors.
  
  Solution:
  To resolve the SZDM_LOCK821 error, you can try the following steps:
  
  
  Check Locks: Use transaction code SM12 to check for any locks on the object. If you find that the object is locked by another user, you may need to wait for that user to complete their transaction or, if appropriate, you can delete the lock (ensure you have the necessary authorizations to do so).
  
  
  Review Authorizations: Ensure that the user has the necessary authorizations to perform the action. You can check this using transaction code SU53 after the error occurs to see if there are any authorization issues.
  
  
  Data Consistency Check: Verify the data for any inconsistencies. You may need to run consistency checks or validation processes depending on the type of data you are working with.
  
  
  System Logs: Check the system logs (transaction code SLG1) for any additional error messages or warnings that might provide more context about the issue.
