to de-activate or disable a button, lets say u want to disable SAVE button once it is clicked...

then in the method where u write code for SAVE button

at the end:

elem_btn_disable->set_attribute(

EXPORTING

name = `DIS_SAVE`

value = abap_false ).

DIS_SAVE should be of type WDY_BOOLEAN in the context.

abap_false means deactivating the button .

if you want to HIDE a button, then type should be WDY_VISIBILITY or WDY_UI_ELEMENT_VISIBLE

& value = 1 .

if you want to do this before screen loads, then do it in the INBOUND plug method of in tht WDDOINIT method.

give points if helpful.

Hi,

Create an attribute of type WDY_BOOLEAN in context. In Layout bind the enable property of button to that attribute. Based on your condition

set the attribute.Here is the example code

wd_context->set_attribute( exporting name = 'INP_FIELDS' value = 'X').

Here INP_FIELDS is the attributein context.
