How can I set up the transaction business category for "Intercompany Transactions" to be assigned w

How can I set up the transaction business category for "Intercompany Transactions" to be assigned when the "Create Intercompany AP Invoice" process creates the invoice lines on AP_INVOICE_LINES_INTERFACE Table?

Currently they are created with Business Transaction Category = "SALES_TRANSACTION" and tax code from AR.

Instead of "INTERCOMPANY_TRANSACTION" and Tax code from AP.

The invoice on AP_INVOICES_INTERFACE  table has correct source='Intercompany'.

Thanks in advance, for any advice about how to correct this issue.
