# Create the data transform for a single-document processing case

> Configure the jsonToInvoiceWithVerificationFields data transform that maps ABBYY FlexiCapture invoice fields and line items to a single-document Pega case.

A single-document processing case needs one data transform. It maps the invoice fields and the line items that ABBYY FlexiCapture returns to the case properties.

For the general procedure, see [Create a set of data transforms in Pega](/flexi-capture/connectors/pega/pega-data-transform-2).

## jsonToInvoiceWithVerificationFields

| Action   | Clipboard        | Relation | JSON            |
| -------- | ---------------- | -------- | --------------- |
| Set      | `.InvoiceNumber` | equal to | `InvoiceNumber` |
| Set      | `.InvoiceDate`   | equal to | `InvoiceDate`   |
| Set      | `.City`          | equal to | `City`          |
| Set      | `.Country`       | equal to | `Country`       |
