# File extension error when uploading attachment

## Resolution

**Issue**

I receive the following error when uploading an attachment to a transaction:

This buyer does not allow attachments with the file extension associated with \<examplefilename.abc>

**Resolution**

You must upload the attachment with a file extension that is accepted by your buyer.

**Cause**

Your buyer has restricted certain file extensions from being used in attachments.

**Additional Information**

You can view the file extensions that your buyer does not accept in the **Attachment File Extension Rules** section of their [transaction rules](https://support.ariba.com/item/view/142286).
