Why the sync error occurs
This error occurs when a payment transaction entry (bill) is attempting to sync from Microsoft Dynamics GP (MSDGP) to Bill.com but the payment transaction entry (bill) is coded to freight, misc, discount, or any field other than purchases. Only payment transaction entries (bills) in Microsoft Dynamics GP (MSDGP) coded to purchases will sync to BDC.
How to fix the sync error
To resolve this error edit the payment transaction entry (bill) in Microsoft Dynamics GP (MSDGP) and code to a purchase.
