Use this activity to Approve an Invoice Preview.
You, as a billing agent, working for the service provider, can Approve an Invoice Preview, once you have verified that the invoicing amounts are correct.
When you approve an invoice preview, a background process will create a Customer Order. To generate the Invoice, you need to further process the generated Customer Order. Approve Online the customer order will be created online from the invoice preview. This is set on the Site.
Note: If the invoice preview is created with atleast one Service Invoice line having a Qty to Invoice of 0, it will not be allowed to approve the invoice preview as lines with zero quantity cannot be invoiced to customer. These lines will need to be manually deleted before the invoice preview can be approved.
