Receivables Recurring Bill Plan - not generating invoices

Summary

Receivables Recurring Bill Plan - not generating invoices after Generate Recurring Billing Data

Content

I created three different Receivables Recurring Bill Plans for one customer, but after running Generate Recurring Billing Data I am not seeing any invoices.

Each plan started 9/1/18, ends 7/31/19, with the first transaction date of 9/30/18.  I created the Plans today, and ran the Generate Recurring Billing Data process after creating the Plans.  I expected to see invoices dated 9/30/18 since it is now past that date.

But there are no transactions created for this one customer (and these are the first transactions for this customer).  I see nothing if I search for transactions for that customer from any date, or if I look at the Bill Plan and look at Review Transactions.
