Hello, maybe you guys are not understanding the question. But let me elaborate. This is going to be a standard dynpro component for Purchase Orders. So i have added a button to the screen. When the user clicks on the button, I want the logic to hit the change badi so that i can do my custom logic based on the values from the other views associated with the PO. Thank you.

As I told you in that linked thread, I'd suggest trying to use SET_CHANGED_BY_CLIENT method on the context of your webdynpro. This is sufficient to make the system aware of a change and trigger the CHANGE badi.

As far as I've observed doing my tests, the CHANGE badi is then triggered after an event that will follow the SET_CHANGED_BY_CLIENT execution.

So I'd suggest two test:

- pre-exit of the method you trigger when the user press your custom buttom: set_changed_by_client and then execute your code. See if the badi is then triggered;

- if not: you could "force" a subsequent action after the button press, for example, a simple REFRESH of the view. Then I'm sure that, after the set_changed_by_client method, the badi will surely be triggered.

Please be aware that I'm absolutely NOT a guru on these arguments, so I'm trying to give you some workarounds I implemented on an SRM 7 system. Probably some guru will have better and cleaner solution for your task, but as far as I've seen, these ones should meet your needs.

hey .. so i should loop at each statndard element and set it to set changed and then refresh the view with /sapsrm/if_cll_xo_mapper~fire_event_refresh ? It is still not working for me.

I can't do a post exit or pre exit because it is a custom method and it is greyed out as well.

hey.. actually i got the element that was selected which is the button and set the set change by client to X. Then i called the refresh /sapsrm/if_cll_xo_mapper~fire_event_refresh but it is still not working.

when i debug i can see the changed by client attribute as X as well. Am i doing something wrong? Thanks!

so this is what i did for my custom button.

element = wd_context->get_lead_selection( ).

CALL METHOD element->set_changed_by_client

EXPORTING

flag = ABAP_TRUE.

call the method wd_comp_controller /sapsrm/if_cll_xo_mapper~fire_event_refresh

and it is not triggering my changed badi. Let me know what is wrong? Thanks!
