# How to handle an empty mapping page

## Introduction

When you [create a service](/product-documentation/patchworks-services/working-with-services/adding-a-patchworks-service.md) between two connectors, you'll typically find that a set of default mappings is added to the [mappings](/product-documentation/patchworks-services/working-with-services/the-anatomy-of-a-service/service-mapping.md) tab. For example:

<div align="left"><figure><img src="/files/xtX1MYoFmuaZ8T9yxiMB" alt="" width="563"><figcaption></figcaption></figure></div>

However, there may be occasions where the mappings page does not contain any default mappings - for example:

<figure><img src="/files/y6PuUfBNYU6uDZ5BxRZ7" alt=""><figcaption></figcaption></figure>

In this scenario, don't panic! It's pretty easy to add your own mappings right here.&#x20;

## Adding your own mapping rows
