# Warnings
**Warnings** are the checks Nifty runs across your inventory to surface problems that are easy to miss.
### Where to find it
Choose which warnings run from Settings → [**Warnings**](https://app.nifty.ai/settings/warnings). Flagged items appear under the [**Issues filter**](/inventory-management/search-sort-and-filter.md#issues-filter) in the Inventory Manager.
### How warnings work
Each warning is evaluated automatically against every item in your inventory. When you turn one on or off, Nifty re-evaluates your whole inventory — it may take a few minutes for flags to appear or clear.
Some warnings are *always on* because the problems they catch almost always need attention. Others are *configurable*, so you can turn them on to fit how you work.
### Always-on warnings
These run for everyone and can't be turned off:
| Warning | What it flags | Why it happens | How to fix it |
| ------------------------- | -------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Partially delisted** | A listing is active on one marketplace but unavailable on another | Most commonly, the item was sold but [**Auto-Delisting**](/auto-delisting/auto-delisting.md) was not enabled or could not complete. Other reasons include human error, the marketplace removing your listing, or external relists | If you want this item delisted, select the row and Delist it.
If you want it listed, use the Listing menu to move delisted listing(s) to a new row, then re-crosslist.
|
| **Mismatched quantities** | The same item has different available quantities on different marketplaces | Either human error, or the item was sold but [**Auto-Adjusting**](/auto-delisting/auto-delisting.md#auto-adjust-quantity) was not enabled or could not complete | Use the **Item menu** to edit the item. Adjust the quantity at the top of the page and publish |
| **Publishing error** | A listing failed to publish | The marketplace rejected the listing (e.g., invalid title format, listing limit reached) | Click the error icon on the cover photo to see the error, fix the issue, and retry |
### Configurable warnings
Turn these on from Settings → [**Warnings**](https://app.nifty.ai/settings/warnings). They're available on the **Crosslisting** and **Bundle** plans.
| Warning | What it flags | Why it happens | How to fix it |
| ----------------------- | --------------------------------------------------------------------------------------- | ------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Price inconsistency** | Items whose prices don't match your [**Pricing Rules**](/crosslisting/pricing-rules.md) | A manual edit, a marketplace promo, or a price adjustment on relist | Select the row and use Update Prices, or edit by hand.
If it's from a sale or promo, no fix is needed — it clears once the sale ends and you Full Sync, or when the item relists.
|
| **Missing SKU** | Items with no SKU set | Human error | Open the item and add a SKU |
{% hint style="info" %}
While the **Missing SKU** warning is on, the SKU field is required when creating or editing an item — so new items don't get flagged the moment you save them.
{% endhint %}

## 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.nifty.ai/inventory-management/warnings.md?ask=&goal=
```
`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.
