Invoices are generated for a payment against a purchase order. The Accounts Payable Specialist \[sn_ap_apm.accounts_payable_specialist\] can access all the invoices and take required actions to process the invoices in Source-to-Pay Workspace.  
Accounts Payable Operations integration with Document Intelligence automatically extracts data from the invoices that are received as an attachment via email, and creates the invoice records and the invoice line records. When the invoice is in certain states during automated invoice processing, manual intervention is required by the Accounts Payable Specialist to move the invoice to the next stage of processing.  
Note:  
Accounts Payable Operations supports invoices of type PO Invoice, Non-PO Invoice, Credit memo.  
The Accounts Payable Specialist can view the invoices by doing the following:

1. Navigate to Accounts Payable OperationsSource-to-Pay Workspace.
2. Select the list icon (![List icon]()).
3. Navigate to ListsInvoices.
