Hi Varun,
As per my knowledge,
1. Enhance the view
2. Add an attribute 'READ_ONLY' type 'WDY_BOOELAN'
3. Bind the attribute to the input field
4. I am not sure on what condition you need to make editable the field, for an idea giving this eg
in case if you want to enable the field based on the onselect of the tab, then there is an event onselect of the tabstrip UI element,
sample code:
lo_el_read_only->set_attribute( name = 'READ_ONLY' value = abap_false ).
Thanks & Regards,
