Hi,
Thank you for reply.

>>If I understand correctly, you are calling an audit object from a form. I believe it is much better to have a trigger called from the table.

No, I am calling audit object from triiger, but the object is created globally - main.prg

Since the object is created in main.prg, so audit object is not able to access tables when I issue REPLACE/INSERT statement from form (private data session)
