I suspected that. I used to write applications using delphi, now I`m learning Forms and I`m facing some stupid problems. I wrote a simple procedure to insert data in a table in When-button-Pressed trigger ... the table belongs to user A, and the user B has the permission to insert data in this table. When I fill in the text items and press the button with user A it works, but when I press the button connected with the user B, oracle forms raises something like 'can`t check exclusivity in a fk constraint' .... I gave to user B all the priviledges related to the table the fk referes to, and nothing. Do you know what`s going on? I just want to insert data using when-button-pressed and not the insert symbol from default&smartbar.

Thanks in advance.
