Document Type for Non-PO invoice

Dear Experts,

We are trying to configure the Non-PO invoice mapping in CIG as per the document below.

However, we can't seem to find the parameter as per the screenshots shared in this article:

In our CIC cross reference, we are only able to configure these options for FIinvoice.

Our goal is to be able to post the Non-PO invoice as document type 'KR'. Currently, they are being processed in our ERP as 'RE'.

Please kindly advise if we are missing a step above.

Best Regards,

Ganiel
