2513889 - Cannot Post the Supplier Invoice to Accounting Due to Error “Sum of item amounts does not match original item amount”

You create a supplier invoice and you are unable to post it due to error as "Sum of item amounts does not match original item amount".

1. Go to General Ledger work center and access Source Documents subview within Closing Cockpit view.
2. Find the source document XXX(ID of the supplier invoice) and you can see the error Message.

Security retention/installments are used while creating the supplier invoice and you have also given a down payment request reference in the same invoice.
Internally a clearing gets created to clear the down payment request with the invoice first and then the system tries to also split the original invoice into multiple invoices as per the installment information in the original supplier invoice.
It is not supported at the moment.

This is system designed behavior , you can follow these steps to solve the issue:

1. Cancel this supplier invoice and create a new one.
2. In the new one,remove either the down payment request reference or the installment information from the invoice and post it.
