Payment of zero amount invoices only through a PPR

Summary:

Content (please ensure you mask any confidential information):

We have to put in place a payment process to clear all the 0 amount invoices, meaning to have these 0 amount invoices in PAID status.
I followed the recommendations in a question dated from 2020 in the CCC:

1. Create Format, use the existing BI template used for actual payments and defined validation that payment amount is zero.
2. Configured payment process profile for zero payments -
   a) Selected all payment methods
   b) select relevant BU's
   c) don't define payment system and don't attach transmission config (As we don't want to send payments to bank)
3. Configure new payment template and attach PPR created in step2.
