Budget Billing Plan (statistical) payments

Hi Experts,

I'm new into Budget billing plan procedures and I have some doubts on how should the amounts be cleared in the BBP statistical procedure.

I set a clearing restriction (1) to the BBP request transactions so that the requested amouts are only cleared during invoicing, this makes all payments posted to the customer account as On-account payments and manual clearing have to be executed to clear payments against the periodic consumption invoice.

-> is this the process correct ?

Otherwise, is there a way to have these payments taken into accounts when invoicing (deducted from the periodic bill)? if so, could somone guide me through the customizing activities to achieve this ?

Thanks in advance
