>How do I create a generic add method that will allow me to save records in two or three different tables, with or without PK ? I have tried and failed many times. Also, I have used the MS.Wizard but it does not work for this type. Plese help.

If PK stands for primary keys, you should have them. Basically, they will 'discipline' you code. However, you should write this code to populate related tables (INSERT-SQL is the best command here). You could either put it into some Form.method or into App.method or into INSERT trigger of your 'first-inserted' table.
