Renato,

Yes it will give you the file in use error, data sessions are really smoke and mirriors, if the dbf ifle is open anywhere then you must use the AGAIN even if it is open in another data session. That is eaxactly what the Data Environment does automatically for you if you put the table in the form's DE.
