The current behavior is that if Table B is added to a subgrid of Table A, the user cannot write to Table B if the user has write permission for Table B only. To write to Table B in the subgrid, the user must have write permission for both Table A and Table B.

If we do not permit editing of Table A, but allow writing to Table B in the subgrid, this is currently not possible. This situation is very inconvenient and we would appreciate an early fix.
