Where you read this?
I use SP rarely and i am not aware of this?
Just remove this block from my example and try it w/o error handling.

>>>It is a variable and I test it within the SP which points to the right folder. In fact, I can read the values from the tables all right. So the table must be opening in the right folder. The problem is that no values are not being written to the table and no new records are inserted. And no error message. Although error message is a moot point since it is hard to trap error in a stored procedure.
