# Limitations

### Limitations

#### **Restoration of System-Generated Chatter-Feed Items**

* **Issue**: Salesforce does not allow the restoration of chatter-feed items generated by the system.
* **Details**: Only feed items manually added by users to the chatter feed can be restored.
* **Error Message**: Attempting to restore system-generated chatter-feed items will result in the error: "Required field missing: Body."

#### **Restoration of Shared Objects Data**

* **Issue**: Salesforce does not permit the restoration of data in shared objects generated by sharing rules.
* **Details**: Only manually added share-related records in the shared object can be restored.

#### **Installed Packages**

* **MuleSoft** operates as an installed package component in Salesforce. Consequently, it cannot be backed up, restored, or replicated using API calls. 
* Installed packages, which includes **MuleSoft** or anything related to Mule, cannot be backed up directly; they must be obtained from the Salesforce AppExchange platform and installed.

**File Size Limits**

* **Issue:** If the metadata zip file exceeds the **file size limit of 39 MB**, then AutoRABIT Vault cannot restore the file to the destination Org. 
* **Details**: Use the workbench to restore larger files. 
* **Error Message in the UI logs**: "Metadata ZIP file exceeds the maximum allowed size of 39 MB. Please refer to the  [AutoRABIT Knowledge Base](https://knowledgebase.autorabit.com/) for more details.” 
* **Additional Info**: Refer to this [Salesforce article](https://developer.salesforce.com/docs/atlas.en-us.salesforce_app_limits_cheatsheet.meta/salesforce_app_limits_cheatsheet/salesforce_app_limits_platform_metadata.htm) for more information on file size limitations.

## 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://knowledgebase.autorabit.com/product-guides/vault/vault-faqs/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.
