Smart SAP Assistant

• What is the cause and solution for SAP error message WSUBST005 - Select one row only ?

  The SAP error message WSUBST005: Select one row only typically occurs in scenarios where a user or a program tries to select multiple rows from a table or list where only a single row selection is allowed.
  
  Cause:
  
  The user has selected more than one row in a selection screen, ALV grid, or any selection list where the application logic expects exactly one row to be selected.
  The program or transaction expects a single row to process further, but multiple rows are selected, causing this error.
  This can also happen if the code explicitly checks for single selection and throws this message when the condition is violated.
  
  
  Solution:
  
  User Action: Select only one row before proceeding. Make sure to highlight or mark exactly one entry.
  Developer Action: If you are a developer or support consultant:
  
  Check the selection logic in the program or screen.
  Ensure that the code validates the number of selected rows and prompts the user accordingly.
  If multiple selections are allowed, adjust the logic to handle multiple rows or change the UI to allow multiple selections.
  Example ABAP check:
  IF lines(selected_rows) <> 1.
    MESSAGE 'Select one row only' TYPE 'E'.
  ENDIF.
  
  
  
  Provide clear instructions or UI hints to users to avoid multiple selections if only one is allowed.
  
  
  Related Information:
