Auto Invoice not applying transaction type for credit memo created by Project Invoicing

Hello,

We have an issue with the projects billing for R12.2.4

When creating Project events for billing that have a negative amount, the auto invoice for AR is not applying the transaction type for the credit memo. Instead of this Oracle AR is using the transaction type for the invoice, and creates an invoice with a negative amount. And due to this we can never apply the negative amount to an invoice, because the transaction does not have the class with type credit memo.

So know I do not know if the issue is with the Project Billing, because we have to launch the con.request "Interface to Receivables", that might insert the inccorect value into the interface table or it is an error of the auto invoice of AR.
