I added the item UPC to our picking tickets. Printing from the sales order works great however when print more than 1 from the Print Checks & Forms I get an Unexpected Error. Any ideas?

Did you customize your picking ticket? Try printing one at a time (using Print Checks & Forms) and see if you get the error. Try a few different orders if you get the error. If it is on all orders, then create a case. If it is order specific, try to figure out what is different about that order. Special characters, longer descriptions, etc. Probably need to create a case either way.

Not order specific. Only happens when printing more than 1.
