AT SELECTION-SCREEN CHECK

 

Note

You should only perform very expensive checks with AT SELECTION-SCREEN if the program is then started.

If the field has one of the values 'ONLI' (= Execute) or 'PRIN' (= Execute and Print), the report is then started,

 

 

eg:

 

FORM F_CHECK_SELECTION_PARAMETERS .
  IF S_KUNWE[] IS INITIAL AND
     S_DN_NO[] IS INITIAL AND
     S_DN_DT[] IS INITIAL AND
     S_SO_NO[] IS INITIAL AND
     S_SO_DT[] IS INITIAL AND
     S_AUART[] IS INITIAL.

    IF  SY-UCOMM  =  'ONLI'.
*   Selection was not restricted
      MESSAGE  W096.
    ENDIF.
  ENDIF.
ENDFORM.                    " F_CHECK_SELECTION_PARAMETERS
