A view is basically like a cursor, except that it is R/W.

It is important to specify the PK correctly, or else, perhaps, when you intend to update a single record, you actually update several.

There is a very important option in the view designer, "Send updates"; if this is not marked, all other update options are ignored!

For showing the view for different sets of child data, please see help under "Requery()".

Hilmar.
