# Supplier Item Number Map
## **Overview**
This feature helps you manage and reconcile item numbers between your system and your suppliers. Often, the item numbers you use internally may not match the item numbers your suppliers use. Docbits makes it easier to handle these discrepancies by creating a mapping between your item numbers and those of your suppliers.
## **How It Works**
{% embed url="" %}
1. **Manual Matching:**
* The first time you encounter a discrepancy between your item number and your supplier's item number, you need to match them manually.
* You can do this by entering the correct supplier item number corresponding to your internal item number.
2. **Automatic Matching:**
* Once you have manually matched an item number with its supplier's item number, Docbits remembers this mapping.
* The next time the same item appears, Docbits will automatically match it based on the stored mapping, saving you time and reducing errors.
## **Interface Breakdown**
* **Supplier ID:** The unique identifier for the supplier.
* **Item Number:** Your internal item number for the product.
* **Supplier Item Number:** The corresponding item number used by the supplier.
* **Action:** Options to manage the mappings, such as deleting incorrect mappings.

## **Benefits**
* **Efficiency:** Reduces the need for repeated manual entry, making the process faster.
* **Accuracy:** Minimizes errors by ensuring that item numbers are correctly matched.
* **Convenience:** Simplifies the workflow by automating the matching process after the initial manual entry.

## 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.docbits.com/end-user-and-partner-section/end-user-section/purchase-order-matching/supplier-item-number-map.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.
