# Limitations

## Format and content

<table><thead><tr><th width="290">Limitation</th><th>Explanation</th></tr></thead><tbody><tr><td><strong>DATANORM 4 and 5 only</strong></td><td>Other formats – Excel price lists, BMEcat or proprietary supplier formats – are not read.</td></tr><tr><td><strong>No image files</strong></td><td>The G record only carries a reference. The image files themselves are not downloaded or stored on the item.</td></tr><tr><td><strong>Text files expected</strong></td><td>Unpack compressed deliveries before importing.</td></tr><tr><td><strong>DOS character set</strong></td><td>Files are read as DOS-encoded. A file converted to UTF-8 beforehand loses its umlauts.</td></tr></tbody></table>

## Prices

<table><thead><tr><th width="290">Limitation</th><th>Explanation</th></tr></thead><tbody><tr><td><strong>One currency per file</strong></td><td>The currency comes from the header record and applies to the whole delivery.</td></tr><tr><td><strong>No automatic sales mark-up</strong></td><td>The app can write the list price as a sales price but calculates no mark-up.</td></tr><tr><td><strong>Discount groups only on request</strong></td><td>Discounts only apply when <strong>Apply Discount Groups to Purchase Price</strong> is on and the <code>.RAB</code> file has been imported.</td></tr><tr><td><strong>No surcharge recalculation</strong></td><td>Copper quotations are carried as information but not converted into a price.</td></tr></tbody></table>

## Part lists

<table><thead><tr><th width="290">Limitation</th><th>Explanation</th></tr></thead><tbody><tr><td><strong>Assembly BOMs only</strong></td><td>Assembly BOMs are created, not production BOMs.</td></tr><tr><td><strong>Components must exist</strong></td><td>Lines whose item has not been imported are skipped and logged.</td></tr><tr><td><strong>Sets are replaced</strong></td><td>A repeat import replaces the existing BOM entirely. Manual additions to a DATANORM BOM are lost.</td></tr><tr><td><strong>Optional lines without selection logic</strong></td><td>Optional lines are either all included or all left out. Guided selection in the sales process is not part of the app.</td></tr></tbody></table>

## Operations

<table><thead><tr><th width="290">Limitation</th><th>Explanation</th></tr></thead><tbody><tr><td><strong>SFTP only via Azure Function</strong></td><td>Business Central online cannot speak SFTP. Without the intermediary function only manual import is possible.</td></tr><tr><td><strong>Default vendor on SFTP import</strong></td><td>Automatically collected files get the default vendor. There is no per-folder or per-filename assignment; correct it with <strong>Assign Vendor</strong>.</td></tr><tr><td><strong>No automatic rollback</strong></td><td>Synchronised items are not removed automatically. That is why you review in staging before approving.</td></tr><tr><td><strong>Import changes master data</strong></td><td>Trial new supplier files in a sandbox first.</td></tr></tbody></table>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.solutioo.de/datanorm-item-import/datanorm_en_us/importing-datanorm-files/limitations.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
