# sFTP File Error: Problem Processing File

When your community receives an email notification with the error **Problem Processing File**, it indicates that an automated or manual file upload was unsuccessful. Follow these steps to identify and resolve the issue.

## How to Identify the Error

1. **Login** to Unimarket.
2. Navigate to the **Administration** module and select **File Processing**.
3. Locate the failed file in the list.
4. **Hover over the "i" icon** (information circle) next to the failed status to view specific details about what the error pertains to.
5. Select the **Error Report** hyperlink to download the CSV file and research and resolve the error(s).

## Common Error Types

Errors typically fall into one of the following categories:

* **Syntax Errors**: Incorrect CSV formatting, such as missing headers or incorrect character encoding.
* **Data Validation**: Missing required fields or using invalid data (e.g., an account code that doesn't exist).
* **Sequence Issues**: Uploading dependent data before the primary data exists (e.g., uploading supplier addresses before the supplier record).
* **Duplicate Invoices Found**: Multiple invoices found with the same identifier associated with the specified supplier name.

## How to Resolve the Issue

1. **Correct the File**: Open your source CSV file and fix the specific data or formatting issue identified in the error message.
2. **Re-upload**: Once corrected, re-upload the file through the **File Processing** screen or place it back in the appropriate sFTP inbound folder.
3. **Verify**: Confirm the status changes to "Success" or "Processed" in the File Processing log.

## Limits & Notes

* **Support Assistance**: If the error message is technical or pertains to a system issue you cannot correct, contact Unimarket Support at `support@unimarket.com`.
* **Outdated Files**: Avoid re-uploading old files if more recent data has already been processed to prevent overwriting current information.

```
GET https://docs.unimarket.com/documentation/file-automation-sftp/sftp-file-error-problem-processing-file.md?ask=<question>&goal=<endgoal>
