• What is the cause and solution for SAP error message WXP412 - Select at least one entry ?

  Certainly! Here's a detailed explanation for the SAP error message WXP412: "Select at least one entry":
  
  Error Message
  WXP412: Select at least one entry
  
  Cause
  This error occurs in SAP Web Dynpro applications when a user tries to proceed or execute an action that requires selecting at least one item from a list or table, but no item has been selected.
  In other words, the application expects the user to mark or highlight one or more entries (rows) in a selection list or table control before continuing. If the user clicks a button or triggers an event without any selection, the system raises this error to enforce the requirement.
  
  When Does It Occur?
  
  In Web Dynpro ABAP applications or custom Web Dynpro components.
  When a UI element (like a button) triggers an action that processes selected entries.
  The underlying code checks the selection and finds none selected.
  Common in scenarios like mass processing, deletion, or modification of list entries.
  
  
  Solution
  
  
  User Action:
  
  Make sure to select at least one entry (row) in the list or table before clicking the button or triggering the action.
  Selection can be done by clicking the checkbox or highlighting the row, depending on the UI design.
  
  
  
  Developer Action (if you are a developer or consultant):
  
  Check the Web Dynpro component/view controller code where the action is handled.
  Ensure that the code properly checks for selected entries before proceeding.
  Provide user-friendly messages or disable the action button until at least one entry is selected.
  Example code snippet to check selection:
  DATA: lt_selected_entries TYPE your_table_type.
  lt_selected_entries = wd_context->get_selected_entries( ).
  IF lt_selected_entries IS INITIAL.
    MESSAGE w412(00) WITH 'Select at least one entry'.
    RETURN.
  ENDIF.
  
  Adjust the UI to make selection easier or more obvious to the user.
