## Limitations

<table><thead><tr><th width="266.79296875">Limitation</th><th>Summary</th></tr></thead><tbody><tr><td>'Hard coded' tax code</td><td>The last map shape in this flow includes a <code>rows.*.taxCode</code> rule, where a transform function outputs the value as <code>T20</code>. Further development would be needed to retrieve and utilise other tax codes.</td></tr></tbody></table>
