Vendor Invoice error

[Liz Young <..hidden..>]

The error listed below occurs in a new dataset after selecting AP > Vendor 
Invoice.  I am trying to add inventory. First I added parts, then tried to 
add inventory via the Vendor Invoice page.

I have a note about this being related to disabling the Audit Trail, but 
darned if I can track where I found that note -- I've searched the bug 
database and the mailing list archives.  Can someone point me in the right 
direction?

Thanks in advance,
Liz
