Implement the invoice quantity check extension point to enable the invoice dispute intake assistant AI agent to validate a customer's quantity dispute claim by reconciling it with delivered quantity data from your Enterprise
Resource Planning (ERP) or inventory system.

## Vorbereitungen

The application scope must be set to Manage Invoice Operations. You can change the application scope using the application picker in the Unified Navigation bar.

Role required: admin

## Warum und wann dieser Vorgang ausgeführt wird

The demo data for the Manage Invoice Operations application includes a sample implementation called `invoiceQuantityCheckDemo` as part of the `sn_inv_ops_aias.invoiceQuantityCheckEP` extension
point. To enable real-world validation of quantity disputes against your external ERP system or inventory delivery records, replace the demo implementation with your own custom logic.

## Prozedur

1. Log in to the ServiceNow instance.
2. Navigate to AllSystem Extension PointsScripted Extension Points.
3. Search for the `sn_inv_ops_aias.invoiceQuantityCheckEP` scripted extension point in the API Name field.
4. View the sample script included in the demo data by selecting sn_inv_ops_aias.invoiceQuantityCheckEP.
5. Create your own implementation of the extension point by selecting the Create implementation related link.
6. On the Script Include form, fill in the fields.  
   For a description of the Script Include form fields, see [Script includes](https://www.servicenow.com/docs/access?context=c_ScriptIncludes&version=australia&pubname=australia-api-reference&ft:locale=en-US).
7. Override the functions in the script to implement your logic for validating the customer's quantity dispute claim.
