A supplier invoice appears as unposted source document in the general ledger due to the error "Sum of item amounts does not match original item amount".

SAP Business ByDesign

1. Go to the General Ledger work center and access Source Documents subview within the Closing Cockpit view.
2. Find the source document XXX( XXX represents the the supplier invoice ID) reporting the error message "Sum of item amounts does not match original item amount".

In the invoice a payment of type Installment or of type Retainage is added as well as down payment:

1. In the invoice go to the General tab.
2. On the bottom go to Payment Information and choose the Payment Details sub-tab. Here, an Installment item or a Retainage item is added.
3. Now go to the Down Payments sub-tab. Here, a down payment item is added. 

• This combination of maintaining installment (or retainage) items as well as assigning down payments in one supplier invoice is not supported.
• During the posting the functionality creates a clearing to split the installments as well as down payments. This can or cannot work. The system behaviour is not reliable here and we do therefore not support the scenario.

The only way to resolve this issue is by cancelling this supplier invoice. 
The cancellation document will also appear as unposted source document. You can then mark both documents as irrelevant (see below).

Then, create two new new supplier invoices, one with the installment and one with the down payment item.
