• What is the cause and solution for SAP error message WY059 - Select a valid line ?

  SAP Error Message:
  
  WY059 - Select a valid line
  
  Cause:
  The error message WY059 - Select a valid line typically occurs in SAP when a user tries to perform an action (such as editing, deleting, or processing) on a list or table without selecting a valid line or row. This means the system expects the user to select a specific line item before proceeding, but no valid selection was made.
  This error is common in SAP modules where line items are displayed in a list or table format (e.g., sales orders, delivery documents, batch processing screens, or workflow tasks), and the user must explicitly select one or more lines to continue.
  
  When does it occur?
  
  When clicking a button or executing a function that requires a line selection, but no line is selected.
  When the selected line is invalid or does not meet the criteria expected by the program.
  When the user interface or screen does not properly register the selection due to UI issues or custom enhancements.
  
  
  Solution:
  
  
  Select a Line:
  
  Ensure that you have selected a valid line item in the list or table before performing the action.
  Click on the checkbox or highlight the row that you want to process.
  
  
  
  Check for UI Issues:
  
  Sometimes, the selection might not be registered due to UI glitches. Try refreshing the screen or re-entering the transaction.
  If using SAP GUI, ensure that the GUI is updated and working correctly.
  
  
  
  Verify Line Validity:
  
  Make sure the line you are selecting is valid for the operation you want to perform. Some lines might be inactive or locked.
  
  
  
  Check for Custom Code or Enhancements:
  
  If this error occurs in a customized transaction or report, check if any user exits, BAdIs, or enhancements are interfering with line selection logic.
