I created a standard function, CanDelete() or something, that checked the child records according to the RI-information. Unfortunately, I can't locate the function right now.
The basic idea is to get the RI-information with the function ADBOBJECTS(), parameter "RELATION", to get a cursor with relations.
The function should be invoked before the TableUpdate().
The corresponding error message might read something like: "I can't delete that record, because there are related records in table (Tablename)."
