• What is the cause and solution for SAP error message WP202 - Please position cursor on a table line ?

  SAP Error Message:
  
  WP202 - Please position cursor on a table line
  
  Cause:
  The error message WP202 typically occurs in SAP when a user tries to perform an action (such as editing, deleting, or processing) on a table control or ALV grid without first selecting or positioning the cursor on a specific line (row) of the table. The system expects the user to highlight or place the cursor on a particular entry to identify which record the action should be applied to.
  
  Explanation:
  
  In SAP screens with table controls or ALV (ABAP List Viewer) grids, many functions require the user to select a row before executing commands.
  If the user triggers an action without selecting a row, the system cannot determine the target record and throws the WP202 message.
  This is a standard validation to prevent ambiguous operations.
  
  
  Solution:
  
  
  Position the Cursor on a Table Line:
  
  Before executing the action (e.g., pressing a button or choosing a menu option), click on the desired row in the table to highlight it.
  Ensure the cursor is visibly placed on the line you want to work with.
  
  
  
  Check User Interaction:
  
  If the user interface is custom or modified, verify that the selection mechanism is working correctly.
  Sometimes, the table control might not register the selection properly due to UI issues or custom coding.
  
  
  
  Technical/Development Side:
  
  If you are a developer, ensure that the program checks for a selected row before proceeding.
  Use statements like GET CURSOR FIELD or check the table control’s current line index.
  Provide user-friendly messages or disable buttons until a row is selected.
  
  
  
  Training/Documentation:
  
  Inform users about the need to select a line before performing actions.
  Add tooltips or instructions on the screen if necessary.

  Summary:
  
  Cause: No table line selected when an action requires it.
  Solution: Select (position cursor on) a table line before executing the action.
  Additional: Check UI and program logic if the problem persists despite correct user action.
