Crediting Partially Invoiced Transactions

Summary

unable to create a credit memo for partially invoiced transactions

Content

Six invoices with partially invoiced transactions were released and interfaced with AR. The partially invoiced transaction is due to the hard limit being reached on the contract line. Once identified, four invoices were credited in full with no issues but two invoices cannot be credited in full. When cancel invoice is selected, a credit memo is created for only the transactions that were invoiced in full however the partially invoiced transaction is flagged as uninvoiced in Manage Project Costs.

Has anyone else experienced this issue and were you able to resolve it?  If so, how?
