Sage 300

A customer with around 80 1099s to print is still on v2012. The 1099 format has changed, of course, and they aren't able to print directly from Sage 300. We are in discussion about upgrading but cannot get it scheduled before the 1099 filing date. …

We are starting to use Sage 300 ERP. The vendors are uploaded. How do we enter in the balances for the 1099s for each vendor we track? Is there a place to override the balance?

What is the best practice for managing this type of 1099 within Sage 300?
