• What is the cause and solution for SAP error message W+620 - No line selected ?

  SAP Error Message:
  
  W+620 No line selected
  
  Cause:
  This warning message appears when an operation that requires the user to select a line (or multiple lines) in a list or table is executed without any line being selected. For example, in transaction screens or reports where you can select one or more entries to process further (like delete, change, or display details), if you press a button or execute a function without selecting any line, SAP issues this warning.
  
  Solution:
  
  Select at least one line in the list or table before executing the action.
  Check the screen or report for checkboxes, radio buttons, or highlighted rows that indicate selection.
  If you are developing or customizing the program, ensure that the selection check is implemented properly before processing the selected lines.
  If the message appears unexpectedly, verify that the user interface is working correctly and that the selection mechanism is visible and functional.
  
  
  Related Information:
