Description: Initializes the empty target record created for a new embedded DBForm.
Execution: On web, it runs only when AddSingleFrame creates a new target record. It does not run when existing frames are loaded. OnGetHeight runs first. The formula then runs in the target DBForm parser and target object/record context, with the target DBForm as sender.
Arguments: MASTER_<EntryName> contains the current value of the corresponding entry in the parent DBForm. One variable is created dynamically for every global parent entry; replace <EntryName> with the actual entry name. The declared common event arguments are not populated.
Result: Any value assigned to Result is ignored. Assign the required target-entry values directly.
Availability: Web only in current implementation. On desktop the event is created and can be edited, but no execution path calls it.
Example:
SetValue("EntryA", MASTER_EntryB);
