• What is the cause and solution for SAP error message TS021 - Position cursor on a valid line ?

  The SAP error message TS021 ("Position cursor on a valid line") typically occurs in the context of SAP GUI when a user attempts to perform an action (like selecting a line in a table or list) without having the cursor positioned on a valid entry. This can happen in various transactions or reports where a selection is required.
  Cause:
  
  Invalid Cursor Position: The cursor is not positioned on a valid line or entry in a list or table. This can happen if the user clicks outside of the valid rows or if the list is empty.
  Empty List: The list or table may not contain any entries, leading to no valid lines to select.
  User Interface Issues: Sometimes, the user interface may not refresh properly, leading to confusion about where the cursor is positioned.
  
  Solution:
  
  Position the Cursor Correctly: Ensure that the cursor is placed on a valid line in the list or table. Click directly on a row that contains data.

  Refresh the Screen: If you suspect a UI issue, try refreshing the screen or navigating away and back to the transaction to reset the view.
  Use Keyboard Navigation: Instead of using the mouse, try using the keyboard (e.g., arrow keys) to navigate to a valid line.
  Consult Documentation: If the issue persists, refer to SAP documentation or help resources for the specific transaction you are using, as there may be additional context or requirements.
