A Process Flow is a set of activities arranged in a sequence to perform a specific task. Combining various activities, that is, Source, Target, Schema, Mapping, or Transformer creates a process flow. A Process Engine controls the execution of a process by starting the execution of process flow instances and all the activities present in a process flow. When the process flow is executed, data from the source is converted to the intermediate form and dispatched to the target.
Activities in a Process Flow can be executed in either of the two modes:
- Synchronous mode: If an activity is synchronous, process flow initiates the execution of that activity, and waits for its completion. The execution of the subsequent activity is initiated only after the completion of the first activity.
Asynchronous mode: If an activity is asynchronous, process flow initiates the execution of that activity and subsequent activities, as defined in the process flow without waiting for the completion of the first activity.
Repository file is not generated for the activities used in the Asynchronous mode.
You can toggle between the two modes from the Activity Properties panel.
Understanding Web Process Designer
Web Process Designer allows you to design business processes and business rules. The Business Process Modeling Notation (BPMN) standard is used to graphically depict business processes. The Process Designer is easy to use and enables both technical and non-technical users to design processes. 
The Web Process Designer screen is divided into following sections:
- Tool Bar

- Repository View

Palette
The Palette contains a list of BPMN graphical elements that are used to define the flow of business processes.
Element | Description | Notation |
|---|---|---|
Activity | An activity is a work that is performed within a business process. The rectangle image displayed in the next column is used to depict an activity in a process flow. |
|
Gateways | A Gateway is used to control the divergence and convergence of a sequence flow. Thus, it determines branching, forking, merging, and joining of paths. |
|
| Start Event | A start event starts the execution of a process. |  |
| Error Intermediate Event | Error Intermediate Event is used to redirect Process Flow execution to an alternate path in case of failure of any activity during process flow execution. |  |
| End Event | An end event, ends the flow of a process flow. |  |
Data Object | Data Objects do not have any direct effect on the sequence flow of the process. They are used to provide additional information for the reader of the process flow diagram. You can add any amount of information in this element. | |
| Hand Tool | A Hand tool is used to move all the activities in the Canvas area. |  |
| Lasso Tool | Lasso tool helps to select multiple BPMN elements from the Canvas Area and move them to another location. |  |
| Create/Remove Space Tool | Space tool is used to increase the space between the two BPMN elements. |  |
| Global Connect Tool | Global Connect Tool used to connect the BPMN elements in Canvas area and it shows the order that activities are performed in a business process. |  |
Repository View
The Repository View lists the Connect Server objects, such as Activities, Actions, and Process Flows.
- Activities: All the activities that can be used to create a process flow are listed in the Activities tab. You can expand the service to select the activity and drag it to canvas area to create a Process Flow.
- Actions: Actions enable necessary control over a process flow. You can select the Action and drag it to Canvas area.
- Process Flows: It displays the existing Process flow. Double-click the process flow to open in on Canvas area.
Canvas Area
The Canvas is the area where a process flow is drawn. BPMN specification and Connect Server activities are dragged onto the Canvas and arranged in a sequence in order to create a process flow. The Canvas can also be resized if an activity is dragged beyond the default size.
You can also perform these activities in the Canvas area:
- Click
