• What is the cause and solution for SAP error message UPWB169 - Wait until the BSP application preview is closed ?

  The SAP error message UPWB169, which states "Wait until the BSP application preview is closed," typically occurs in the context of using the Business Server Pages (BSP) applications within the SAP environment. This error indicates that there is an ongoing process or session related to the BSP application that needs to be completed or closed before you can proceed with your actions.
  Cause:
  
  Active Session: The error usually arises when there is an active preview session of a BSP application that has not been closed. This can happen if a user is currently viewing or testing the BSP application in a browser.
  Locking Mechanism: SAP uses a locking mechanism to prevent multiple users from making changes to the same BSP application simultaneously. If one user is previewing the application, others may be blocked from making changes until the preview is closed.
  
  Solution:
  
  Close the Preview: The most straightforward solution is to close the browser window or tab where the BSP application is being previewed. Once the preview is closed, you should be able to proceed without encountering the error.
  Check for Active Sessions: If you are unsure whether there is an active session, you can check the transaction SM04 (User Overview) or AL08 (Global User Overview) to see if there are any active sessions related to the BSP application.
  Wait for Timeout: If the preview is not closed manually, it may eventually time out. However, this can take some time, so it is generally better to close it manually if possible.
  Restart the Application: If you are still facing issues, you may consider restarting the BSP application or the SAP GUI session to clear any locks.
