• What is the cause and solution for SAP error message W9009 - Please position cursor on a valid line ?

  SAP Error Message:
  
  W9009 Please position cursor on a valid line
  
  Cause:
  This warning message typically appears in SAP when a user tries to perform an action (such as editing, deleting, or processing) on a list or table but the cursor is not positioned on a valid or selectable line item. In other words, the system expects the user to select a specific line or row before proceeding, but the cursor is either on a header, footer, empty line, or outside the valid data area.
  Common scenarios include:
  
  Trying to delete or change an entry in a list without selecting a line.
  Attempting to execute a function that requires a line selection in ALV grids or custom reports.
  Navigating or processing data in a table control or list where no line is highlighted.
  
  
  Solution:
  
  Position the cursor on a valid line: Before executing the action, click on or navigate to a valid data row in the list or table.
  Ensure a line is selected: In some cases, you may need to explicitly select a line (e.g., by clicking the checkbox or highlighting the row).
  Check the UI element: Make sure you are interacting with the correct part of the screen (not on headers, empty rows, or summary lines).
  If using custom programs: Developers should ensure that the program checks for a valid line selection before proceeding with actions that require it.
  
  
  Related Information:
  
  This message is a warning (W) type, meaning it alerts the user but may not stop the program entirely.
  It is commonly encountered in ALV (ABAP List Viewer) reports or custom transaction screens where line selection is mandatory.
  If you are a developer, you can handle this by checking the selected row index or using function modules like REUSE_ALV_GRID_DISPLAY with proper event handling to ensure a line is selected.
  Users should be trained to always select or position the cursor on the relevant line before performing line-specific actions.
  
  
  Summary:
  
  The message "W9009 Please position cursor on a valid line" means you need to select or place the cursor on a valid data line before proceeding. Simply click on the desired row in the list or table and then retry the action.
