In tcode OBB9.
maintain installment for Z001 or main payment term
Main Payment Term

So, your payment Z001 - 90% on proforma (immd.) & 10% on original invoice is ready to use in sales order.
Try your this and share you feedback.
FYI, payment terms are configured by FI guys.
I think that you need not only settings on OBB8 and OBB9 to split the payments at the interface to accounting during billing. You need to use enhancements to determine the amount of each payment, because if in your country you have a complex scheme to determite VAT, I think that OBB8 settings will not be enough. Please see Note 301077 - User exits for the interface to accounting (EXIT_SAPLV60B_008). See also Note 611040 - Down payment invoice for Italy as a template related with this enhancement. Although this note is for down payment, it will help you to understand how to do this modifitications in include ZXVVFU08. It's an idea.
I hope this helps you
