When I want to generate an invoice to an order following error is displayed:
"There has been an error: An Invoice could not be generated. The purchase order does not have any applicable periods to be invoiced. Verify the data of the purchase order or contact customer service to review your business rules."
I disabled pro-rating and I set following settings to plug-ins:
Invoice presentation com.sapienter.jbilling.server.pluggableTask.InvoiceCompositionTask
Billing process: order periods calculation com.sapienter.jbilling.server.pluggableTask.OrderPeriodTask
It is not working yet. Any Idea? help me quickly please. Thanks a lot.
