3293090 - Credit memos sometimes caused re-reconciliation of invoices besides the one referenced in the credit memo

Some line-item credit memos were reconciled against invoices in addition to the invoice referenced in the credit memo. These credit memos were reconciled against other invoices related to the same purchase order in cases where there were line items that weren't received yet. This behavior caused issues with received quantities and amounts on the order.

In general, when SAP Ariba Buying and Invoicing gets a credit memo for the full invoiced amount, the corresponding invoice is re-reconciled. As a result, any exceptions on the associated invoice reconciliation (IR) document are accepted automatically. 

If there are multiple invoices associated with the same purchase order, and the line items haven't been received yet, the system checks for invoices to re-reconcile based on the order in which they were created, starting with the first invoice. However, the first invoice isn't necessarily the one referenced in the credit memo.
