Hello,
It would have been helpful to see a screenshot of of your UI Action and it's setting so far, as well as where on the CSM form you're talking about that you'd like the login user who clicked the button to be placed.
If the UI Action is client side, then you can review using g_user: https://developer.servicenow.com/dev.do#!/learn/learning-plans/tokyo/servicenow_administrator/app_st...
and then simply g_form.setValue('field_name', g_user_method_from_link);
Otherwise, if it's a server side UI Action, then you get use the standard GlideSystem User Object API: https://servicenowguru.com/scripting/user-object-cheat-sheet/ and then something like:
current.setValue('field_name', gs.getUserObject_link_method);
current.update();
Please mark reply as Helpful/Accept Solution, if applicable. Thanks!
