RMA Created with Positive Amount Instead of Negative – AR Interface Error

We encountered an issue while creating an RMA in Oracle Fusion Order Management, manually override the defaulted item amount but forgot to apply the negative sign.

As a result, both the line and header amounts were saved as positive. The RMA/Sales Order was submitted successfully without any validation error. However, the transaction is now stuck in the AR interface with the following error:

"The document created must have a negative amount total, because the creation sign of the transaction type is Negative."

Has anyone faced a similar issue?

• Is there a way to correct or reverse this transaction since it cannot be updated directly in the AR interface?
