# Source - Design (Map)

The **Source** pane is split into two tabs - **Source Data**, and **Parameters**. This is the definition of the source that data is to be read from.

## Source Data Tab

The **Source Data** tab will display the detail that has been pulled from the source definition that was listed on the main mapping screen. In this example below, the source definition is a **File Definition** called **Excel File Def 1**.

**Excel File Def 1** contains the following - an **Excel** file called **FMEPRECALLS**. Depending on the definition selected, this could be any type of source data.

So in the Map, the file **FMEPRECALLS** appears under **Source Data**.

Click on **FMEPRECALLS** to expand and display the contents of this file into the lower panel.

## Parameters Tab

Click on this tab to identify and list any **Parameters** that are specific to this **Map** in the upper panel, and any **Global Parameters** in the lower panel.

For more information about **Global Parameters**, please review [Parameters](/statelake/administering-statelake/designer/global-setup/parameters/).

For more information about **Local Parameters**, please review [Parameters Tab (Map)](/statelake/administering-statelake/designer/map/parameters-tab-map/).
