If your bill run has been in Post in Progress for a long time and you would like to confirm the bill run is still running in the backned and is posting draft invoices, you can use Data Source Export to know how many draft invoices are remaining to be posted.
Choose object Invoice and filter Invoice: (Invoice.SourceId = 'BR-00001321' and Invoice.Status = 'Draft')
The remaining draft invoice number is 31912 in this case. If you execute this export a few seconds later, the number should decrease until it is 0.
If the remaining draft invoice number has not been updated for minutes and the bill run is in Post in Progress, reach out to Zuora Global Support team via https://support.zuora.com to get further assistance.
