• What is the cause and solution for SAP error message /LTB/TR_UI132 - Navigation not possible; limit of nested screens reached ?

  The SAP error message /LTB/TR_UI132 Navigation not possible; limit of nested screens reached typically occurs when a user tries to navigate through too many nested screens or transactions in the SAP GUI. This can happen in various scenarios, especially when using complex transactions or when multiple pop-up windows are opened.
  Cause:
  
  Nested Screens: SAP has a limit on the number of nested screens (or dialog boxes) that can be opened at one time. When this limit is exceeded, the system throws this error.
  Transaction Flow: If a user is navigating through multiple transactions that open new screens without closing previous ones, it can lead to this error.
  System Configuration: The limit on nested screens can also be influenced by system settings or configurations.
  
  Solution:
  
  Close Unused Screens: The simplest solution is to close any unnecessary screens or dialog boxes that are currently open. This can help free up space for new transactions.
  Use Transaction Codes: Instead of navigating through multiple screens, try using transaction codes directly to access the desired functionality.
  Check for Loops: Ensure that there are no loops in your navigation that could be causing excessive screen openings.
  System Settings: If you frequently encounter this issue, it may be worth discussing with your SAP Basis team to see if the limit can be adjusted in the system settings. However, this is generally not recommended as it can lead to performance issues.
  Session Management: Use the SAP GUI's session management features to manage your sessions more effectively. You can limit the number of open sessions or use the "Session" menu to navigate between them.
