Pre-approval & direct invoice functionality

Hello,

I'm trying to generate invoices with having checked both DIRECT_INVOICE & PRE_APPROVAL_FLG in the billing plan (CA_BILL_PLAN). However, while CA_BI_INTFC completes successfully and system immediately launch CABIDIR1 job it fails at invoice finalization step (BIIVC000). Custemers are also marked as Direct Invoice in Bill to Option. Below is the screenshot of the warning message:

Before I raise a SR is there anything else that we need to do check or change on configuration side?

Thank you for your help
