Add Custom Parameters

After creating property pages, you can add parameters (fields) to them. Custom parameters are often used to give users a different presentation for a parameter needed for the base operator. For example, you can add a parameter to present a list of values that you want users to select from, rather than using an edit box with no defined values. Parameters are also used to capture input that is then used in an expression to calculate one or more base operator parameters. Also, parameters are used to present an interface to users with appropriate terminology.

Unless you set their Read Only, Disabled, or Hidden properties to true, custom parameters that you add to your custom operator are visible and configurable by end users in your Custom Operator Properties palette in the Process Designer or in the Schedule Editor.

Follow these steps:

1. In the Library Browser, double-click a custom operator.
2. In the toolbar, click Check Out.
3. In the Custom Operator designer window, click the Form tab.
4. In the Form Elements pane, expand all of the following:
   1. Form Elements
   2. Page Layout and any pages under your custom operator
5. Drag a form element from the Form Elements down to the page for your custom operator. You cannot drag a field directly onto the form layout.
6. Click the new field to edit its properties. Rename the new field to a meaningful identifier using the Label property. Use the Rename toolbar button to rename certain fields such as check boxes.

   Each field name corresponds to a named field in the Custom Operator Properties palette in the Process Designer.

7. The order of the fields in the Properties palette also corresponds to the order shown on the Form tab. Select an element and click Move Up or Move Down from the toolbar to move it up or down in the list.

To remove a parameter:

1. Select the page.
2. In the toolbar, click Remove.
