You need to write the code under at selection-screen or even you can write under start-of-selection.

if p_1 is 'X'

if p_2 is 'X'.

message'.

endif.

Reward points if it is helpful

Hi,

You can use the event AT SELECTION-SCREEN.

Check this ex..



PARAMETERS: P_MATNR TYPE MATNR,
                        P_WERKS TYPE WERKS_D.

AT SELECTION-SCREEN.

* If both the parameters are entered raise an error message.
IF NOT P_MATNR IS INITIAL AND
   NOT P_WERKS IS INITIAL.
  MESSAGE E208(00) WITH 'You cannot enter both of them'.
ENDIF.

* One of them should be mandatory.
IF P_MATNR  IS INITIAL AND
    P_WERKS IS INITIAL.
  MESSAGE E208(00) WITH 'Enter one of them'.
ENDIF.

Thanks,

Naren
