  The SAP error message RSDA502 indicates that there is an issue with changing the status of an active near-line storage (NLS) connection. Specifically, it means that you are trying to change an active near-line connection from one state to another, which is not allowed.
  Cause:
  The error occurs because:
  
  The near-line connection you are trying to modify is currently active, meaning it is in use or has been activated in the system.
  SAP does not allow changes to active connections to ensure data integrity and consistency.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Deactivate the Connection: Before making any changes to the near-line connection, you need to deactivate it. This can typically be done in the SAP GUI:
  
  Go to the transaction code for managing near-line storage connections (e.g., DBACOCKPIT or RSNLS).
  Locate the active near-line connection you want to change.
  Deactivate the connection.
  
  
  
  Make the Required Changes: Once the connection is deactivated, you can proceed to make the necessary changes to the connection settings.
  
  
  Reactivate the Connection: After making the changes, reactivate the near-line connection to ensure it is available for use.
  
  
  Check for Dependencies: Ensure that there are no ongoing processes or dependencies that might be using the near-line connection before deactivating it.
