Is it mandatory for a Service Call Step to have a screen step?

In the context of workflow design within Informatica Cloud, a Service Call Step does not require a screen step to be included. This means that you can initiate a service call as part of a workflow or task without the need for user interaction through a graphical interface, which a screen step typically provides.

Service Call Steps are designed to trigger backend processes and can operate entirely in the background, allowing for automation and integration without user interface constraints. As a result, there are numerous use cases where a service call might be implemented purely for data processing, API integration, or system communication without the need for immediate visual feedback through a screen step.

Screen steps, on the other hand, are primarily interactive and are often used to gather inputs from users or present information. Since the use case for a Service Call Step can vary widely and many operations do not require user interaction, it is clear why having a screen step is not a mandatory condition for Service Call Steps.
