yes, this is the default tray for the user running the import. As far as I know, there is no way to use several "failure"-trays for different jobs.
Also, I have not seen much specific documentation, I only know of what you can find in the KB and on help.docuware.com
The most common problems when failure sends the document to the tray, but not to the cabinet are the following:
1. missing required fields
2. wrong data type (e.g. storing with .dwcontrol file which tries to write a date into a decimal field, text into anything works fine)
3. field entry is not from select list (when enforcing select lists, might be case sensitive here)
4. when storing with .dwcontrol, an empty decimal, date or keyword field might not get parsed correctly - better to leave it out from the .dwcontrol completely if empty
Those are the problems I usually face here.
Hope this helps.
