What is Best Way to Create Billing Contract Invoice with Non-Cumulative Retainage Rule?

Trying to determine the best way to create new Billing Contract invoices with a non-cumulative retainage rule as having prior retainage and sometimes prior billed amounts on the billing lines. Currently set the Process processing option on the R52121 Invoice Generation report or interactive application for the Zero Invoice Processing to 1 - 'Zero Amount Invoices Allowed' and this creates amounts on some billing lines. Have requested Oracle Support to correct through ESUs and have applied these ESUs with testing results the same.

Wondering if setting the Process processing option for Zero Invoice Processing to 2 - 'Initialize to Zero' on the R52121 Invoice Generation report or interactive application would be best?
