Hi,

I am not able to disable button. my requirement is to disable button after clicking the same button by user. so that user will not able to click again. I tried mant SCREEN options allready but unsuccessfull.

Similar code is working fine for text-filed in my code and able to enable and disable text field on button click

Here is problamatic code.

CASE sy-ucomm .

WHEN 'B_BACK'.

leave TO SCREEN 0.

WHEN 'B_SAVE'. " --> button tcode is B_SAVE

LOOP AT SCREEN. "----

> Problem is here

IF screen-name = 'B_NAME_SAVE'. "--> name of button is B_NAME_SAVE

screen-active = '0'. "screen-invisible = 1. "screen-output = 0. "screen-active = 0.

MODIFY SCREEN.

EXIT.

ENDIF.

ENDLOOP .

ENDCASE.

ENDMODULE.

hi,

EXIT is control break statement for loop nothing wrong to use this....whenever logic required to exit from the loop it used.

Gaurav
