I'm using an xmlmap connector to create an insert into a slq table. everything works correctly, I recently had to add a field for each record I insert that must contain the name of the file I'm importing (which is the same name as the output mapping xml file for the slq connector)

There is no way I can create the mapping via the script. I searched for examples and other topics, I use this simple command

<arc:set attr="result.text">;Filename]</arc:set>

The error in the log i have is:

The value of the attribute could not be accessed: The attribute does not exist.

I have no indication of the reason and I have already made many attempts, any suggestion or idea is welcome, thanks in advance for any help you wish to give me.
Best Regards.
