3752646 - Is it expected that an invoice with only negative amounts is treated as a credit memo in S/4HANA?

When an invoice is created in SAP Ariba Buying and Invoicing with all negative line amounts, the outbound payload sent to S/4HANA via CIG does not include the INVOICE_IND indicator, and the transaction is processed as a credit memo in S/4HANA.

Additionally, when an invoice contains mixed positive and negative line amounts with the parameter Application.Invoicing.ExportPositiveAndNegativeLineAmountInvoices enabled, the transaction may still be processed as a credit memo in S/4HANA if the net document amount is negative.
