Invoice Number Different in OM vs AR

Summary:

The Invoice number is showing different information for the same SO in Order Management and Accounts Receivables

Content (required):

When creating a Sales Order in Order Management the Invoice number that is showing in the Fulfillment Lines for some reason is being created as a different number from the Invoice number available in the Acccounts Receivables that you get when you check for the same Sales Order. We determined that by enabling the AR_TAX_PTNR_CALLBACK lookup code, the customer is not encountering this issue anymore for newly created Sales Orders, but the previously created sales order are keeping this same behavior, is there a way to correct them?
