I need to change the Page Header of a Document Record from "New Record" to something else (say "Summary").
The displayed value is currently set to the "Number" field in Documents. But for the records that I am trying to change this header caption for, the "Number" field will be empty. Hence, I had tried to put a constant value to the "Number" field through advanced settings.
I have also tried to modify PageHeaderTemplate localizable string from the DocumentPageV2 schema, but none of these changes seem to be working.
Could anyone guide me on how this can be achieved?
Note: I am trying to implement this change only for records that are already existing in the system and not when creating any new records.
Thanks in advance.
