Creating a User Parameter

Creating a user parameter is a simple way to quickly expose a parameter in the workspace. This is useful if you want to set visible default values, or if you want to be able to easily change a parameter from workspace to workspace.

There are different ways to create user parameters:

The method you choose will determine the fields that show in the Add/Edit Parameter dialog. Fixed parameters will not be shown; all parameters are described following the table.

Tip: If you have never worked with Parameters, it is easier to start with an existing parameter because the Type will automatically be chosen.

User Parameter Type Description Add/Edit Parameter Dialog
To add a new user parameter that has no existing properties

Right-click the User Parameters icon in the Navigator, and click Add Parameter.

This is a new parameter, so you will have to fill in all required fields.

Click OK to add the parameter to the workspace.

To create a user parameter from an existing workspace parameter

Right-click a Workspace Parameter in the Navigator, and click Create User Parameter.

Most fields are already filled in based on the parameter's existing information. You can edit the fields; however, changing the Type is not recommended.

Click OK to add the parameter to the workspace.

Detailed example: See Publishing a Parameter in the FME Workbench help.
