You cannot add or change a record because a related record is required in
table <name>. (Error 3201)
When 1 builds a one to many relationship and enforces referential integrity,
the system keeps you from adding, changing, or deleting a record from the
many side, before creating a record on the one side.
This effectively, for instance, keeps one from adding or deleting an order,
if there is no customer.
To resolve the error, make sure you have a one-side record first.
