FICAx - One time customer without SD

Hi,

I cannot find a FICAx group, so I decide to post my doubt here.

We are on S/4 HANA Core 1511. So, I would like to know if we can use one time customer on FICAx without uses SD. If it is possible, what is the tcode? And the process how is it works? Should I assigns BP function to customer as is on FI?

Thanks in advance.
