Importing vendor opening balance

Hello,

I want to import vendor opening balance in Nav 2009. I have created a dataport with dataitem vendor and dataport fields No, balance. However when I run the dataport the vendor balance is not updated.

Can someone please advise?

Thanks,

Teena

The balance is made up of the open ledger entries - you need to bring in the transactions as a journal and post it. You cannot simply force a value into a flow field, what would be the point - how would you pay one of the open transactions that make up the balance without it being there?
