The supported payload formats are cXML, JSON and XML. * **[Rules based engine](https://servicenow-prod.fluidtopics.net/bOrfSF542WcPhdcggpVb_w)** The rule based engine maps the invoice line with purchase order line using fields such as unit price, delivered unit price, exact description, exact amount and amount round off. * **[Work with invoices](https://servicenow-prod.fluidtopics.net/vpZfIG38U8aiGCaQHyyuDQ)** Invoices are generated for a payment against a purchase order.

However, the Accounts Payable Specialist may need to manually create a new invoice or update details of a partially created invoice in situations where the automated invoice creation process encounters issues or is not available. * **[Invoice exceptions](https://servicenow-prod.fluidtopics.net/IyXgSahnO3KZN8nsBjtBXw)** Invoice exceptions are discrepancies identified during invoice processing that must be resolved before payment, such as missing information, tax variances, or supplier issues. * **[Tolerance Rules and Variances for invoices](https://servicenow-prod.fluidtopics.net/ULJvN5hmmS8PEvCIg4jQzA)** Tolerance rules define the limits set on an invoice to determine the permissible amount of variance that can be applied to an invoice before the invoice total exceeds the tolerance limit. * **[Invoice approvals](https://servicenow-prod.fluidtopics.net/vrNSVQBVP03wVQyX1~ze6w)** Invoices with the No exceptions found status are eligible for approval. * **[View invoice documents in the Source-to-Pay Workspace](https://servicenow-prod.fluidtopics.net/~wWYOVX7SO2X3zd9k1mNkA)** View the invoice documents directly in the Source-to-Pay Workspace using Document Viewer without having to download them. **Related concepts** * [Invoice case categories and subcategories](https://servicenow-prod.fluidtopics.net/n7zeI9j5cz5DSAL0NINP~w "An agent and Accounts Payable Specialist can access and work on the invoice cases in the Accounts Payable workspace.") * [Using Invoice Case Management](https://servicenow-prod.fluidtopics.net/F2To1EesNPWzTAdSlkAxxw "Agents can use Invoice Case Management to manage and work on invoice inquiry cases raised by employees and suppliers to resolve issues related to invoices.") * [Advanced Work Assignment in Accounts Payable Operations](https://servicenow-prod.fluidtopics.net/lhR8yPdETF~ii3Ov_vkGDQ "Advanced Work Assignment (AWA) automatically assigns work items to Accounts Payable Operations agents based on their availability, capacity and skills.
