To step through a top-level service, you must have Execute, Read, and List access to the service.

To step through all the services within a top-level service, you must have Execute, List, and Read access to all services invoked by the top-level service. If you do not have access to services invoked by the top-level service, Designer “steps over” those services. (Integration Server performs ACL checking for a child service when the Enforce execute ACL property for the service is set to Always.) Designer executes the top-level service and continues to the next flow step. Designer does not step into the top-level service.

To debug a service by sending an XML file to a service, you must have Read access to the service.

To set a breakpoint in a service, you must have Read access to the service.
