# Error File Format

Error files are comma delimited csv files and contain no header row.

# Error File Naming Convention

If an order file is unsuccessfully processed, an error file is placed in the response folder in the format `{original filename}_error.csv`, where `{original filename}` is the original file name that was processed from the upload directory.

# Error File Format

* **Item\_id:** item\_id from order file
* **Unique\_identifier:** Unique identifier from order file
* **Field:** Field that causes the file to be rejected
* **Description:** Description of error (field value too large or incorrect data type)

> 📘 If more than one error is encountered in a record, only the first error is listed in the error file.
