how to access parent page

Hello, assume there’s a table control in a section.

The table control is attached to a data class Data-A, the section is under case type class Work-B

in the table control, I set a click event action on a field, in the action (context is Data-A) I want to run DT AAA of class Work-B, how could I config this? I tried Top.pyWorkPage and ToplevelPage.pyWorkPage, both not works. Thanks.

Define the class for the ‘Top’ page or ‘Primary’ page in ‘Pages and Classes’ tab and call the data transform. It should work.
