Maybe you need a form propery and set its value in GotFocus - LostFocus of your grid.
Something like...
Grid GotFocus event:

THISFORM.TargetTable = '{child_table}'

Grid LostFocus event:

THISFORM.TargetTable = '{parent_table}'

and AddNew() nethod of your form...

DO CASE 
CASE THISFORM.TargetTable = {parent_table}
	... insert code for parent table
CASE THISFORM.TargetTable = {child_table}
	... insert code for child table
ENDCASE
