Hi,

Try it,

MODULE ZNUM1 INPUT.

loop at screen.

IF SCREEN-NAME = 'NUM1'.

IF NUM1 < 4.

SCREEN-input = 1.

else.

SCREEN-input = 0.

ENDIF.

ENDIF.

modify screen.

endloop.

ENDMODULE.

Hi Gopi,

The main thing here is ... the MODULE ZNUM1 should be a PBO module.

MODULE ZNUM1 OUTPUT.

ENDMODULE.

Also, set the SCREEN-INPUT (0 for inactive and 1 for activE) and also set SCREEN-ACTIVE = '1'.

This should help.

Main thing (once again) it's a PBO module NOT PAI.

Regards,

Aditya
