Hello experts.
I ask your help.
I have a custom component usage(B) for a standard component(A). This B component have "Edit" button "Edit". I want to make editable main component A (for subsequent storing data on the "Save") when I click on button "Edit".
In other words, how can I catch the event of the B component usage in the main component A.
Maybe it's the events of controller interface or CALL METHOD iv_usage->subscribe_event...
Please tell me the steps to catch event from reusing view.
