Unnecessary Fields in the User Interface

Question

Attempting send an email using the email connector.

The email connector has an integration between two activities.

In the Integration window of email connector, the Input parameters for from, subject, body, etc., need to be configured.

At the moment, this window is only allowing to map to a field in the UI.

Do fields have to be created in the UI containing these values and map those fields to these controls?

Please see the attached screen for the same.

Is it possible to map static values / dynamic values (from an expression editor / data object / entities) instead of designing the fields in the UI for the purpose of sending the emails and hiding the fields always to user?

Is there a better way of doing it?

Answer

The Integration Wizard on an activityA specific step in a process.  It will be the user interface for that step (web form or a screen), for example, the Leave Application (screen interface or web form) will be the first Activity in the Leave Requisition process.  The Leave Application Authorization will be the second step or Activity in the Leave Requisition process.  One Process can have multiple activities. requires that inputs and outputs be mapped to fields.

It is possible, however, to load a dynamic value into the field via expressions, entities or managed code before the connector integration runs.
