Hello. We're integrated with SFDC, and pass in the SF Opportunity ID to a Sales Order. When we receive a deposit against the SO, we have a custom field on the Deposit record that is sourced from the Opp ID on the SO. We do this same thing on the invoice, we source the opp id from the SO. However, the Payment appears to be a little tricker. Does anyone know if it's possible to source a field on the payment from the Invoice?
