## Transaction import (XML I-file)

Each sample uses `disposition="test"`, which marks the file as non-production data so it is not processed for settlement.

### Sales by currency precision

Different currencies require different decimal formatting in the `transactionAmount` field. The samples below show how to handle 0, 2, and 3 decimal place currencies.

> [accordion] Sale with a 2-decimal currency (USD)
>
> A standard DCC sale where the cardholder accepts the offer and pays in USD. Most currencies use 2 decimal places.

### Multi-merchant examples by channel

The samples above show individual transaction types. The following files contain complete multi-merchant, multi-transaction I-files that demonstrate how different channels structure their data. Use them alongside the field mapping pages to understand how scheme data elements populate each field.

> [accordion] POS and eCommerce (dual message)
>
> A complete I-file with three transactions across two merchants: a DCC-accepted contactless sale, a DCC-declined chip sale (rate `1.0000`), and an eCommerce refund. Use this alongside the [POS and eCommerce field mapping](https://docs.fexco.com/dcc/developer-resources/file-formats/pos-ecommerce-ifile-field-mapping.md) page.

> The `.DAT` files are plain text with fixed-length fields. Open them in a code editor with a column ruler (such as VS Code, UltraEdit, or Notepad++) so you can verify that each field starts at the correct position. The `.DAT.TXT` files are human-readable processing summaries that open in any text editor.

Every set contains five files:

| File prefix | Description |
| :- | :- |
| `I` | The transaction I-file you submit to Fexco. |
| `A` | Currency breakdown report returned by Fexco. |
| `B` | Duplicate of the A-file currency breakdown report. |
| `C` | Settlement response file with per-merchant totals. |
| `C (.TXT)` | Human-readable processing summary report. |

> [accordion] Sales only
>
> A file containing only sale transactions (`J1` transaction code). Use this to verify your system produces correct sale records.
