Creating a new DMRActn field to put on the Reject tab

I’m trying to create a custom field on DMRActn Processing but it’s not editable. I created the field on DMRActn but in customization entry it only appears in the list on DMRActnReject?

How I can get that field to be editable on the DMR Processing screen and bind it to DMRActn, not DMRActnReject?

This where the adapter is using logic to help the screen, but complicates the code.
You likely can only add the field on the tab for that DMRActn type (reject/opr/etc). The adapter will merge it back to the real database table.

I ended up adding the field to the DMR head instead of trying to fiddle around with DMRActn.
