The ITAM-APO integration is designed to streamline invoice processing for ITAM-related purchase orders (POs), verifying better accuracy, exception handling, and operational efficiency.

## Before you begin

Role required: Accounts_payable_specialist \[sn_ap_apm.accounts_payable_specialist\]

## Procedure

1. Navigate to Source-to-WorkspaceAccounts Payable Operations.
2. Create a purchase order in ITAM.  
   For more information on creating purchase order in ITAM, see [Create a purchase order](https://www.servicenow.com/docs/access?context=t_CreateAPurchaseOrder&version=yokohama&pubname=yokohama-it-asset-management&ft:locale=en-US).
3. Create an invoice with the ITAM purchase order.  
   For more information on invoices, [Create an invoice manually](https://servicenow-prod.fluidtopics.net/XJSW9OMemkgk36_~CdAtnQ "As an Accounts Payable Specialist, you can create an invoice manually from the Source-to-Pay Workspace when the automated invoice creation process is encountering issues or not available."). The Accounts Payable Operations checks whether the received quantity in the ITAM receiving slip matches the invoiced quantity. In case of mismatch, an insufficient goods receipt exception is triggered and automatically the ITAM user is notified through email. For more information on exceptions, see [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.").
4. The Accounts Payable Operations automatically verifies and revalidates the invoice.

## Result

The invoice processing of ITAM purchase order is successfully performed.
