Process Canvas Overview

In the upper left you will find tabs to switch between the process canvas and the logs generated from this specific process.

In the bottom left, you will find a panel with tabs:

Services: List of all available services. These are the tools you will use to build your process.

Input Data: This is where you specify the inputs to your process.

Output Data: This is where the output is shown when you 'Run' or 'Run in Step'.

Configuration Settings: These are application level variables that you may want to reference.

In the middle, you will find a toolbar and the actual canvas under it. This is the big area with a grid pattern over it. This is the place where you can implement logic like insert values to database, call JDE business functions, etc. Any programming task could be implemented via this screen.

Toolbar:

Here is a very brief explanation of what some of the non-obvious buttons do:

Build: This is like compiling the process.

Run Process: This is to execute the entire process in one go utilizing the Input Data entered in the left panel.

Run Process in steps: This is very useful while debugging a process. It executes the process one service at a time utilizing the Input Data in the left panel.

Make Connection Longer: Extends the outbound arrow of the currently selected service.

Remove Bends: Attempts to make all arrows completely vertical or horizontal in relation to the services they are connected to.

Create ForEach: Adds a For-Each Start and End service to your process.

To your right, you will find a panel with tabs at the bottom:

Properties: Shows the service specific properties.

Recommended Values: Shows the recommended values from your webpart and/or process. This also includes some pre-built useful EASYProcess functions.

Logs: Shows the logs for this process.


Process Design

Every new process begins with a “Start” and “Terminate” service. Both of these accept no input and cannot be configured any further. If you ever accidentally remove the Start or End services and need to add them back to your process canvas, they can be found in the “Process Flow Elements” Workshop.

Each process can have only one “Start” service, but can have many “Terminate” services. This is because the process can branch out in many different process branches depending on the possible cases.

To begin designing your process, you will need to drag the connector nodes of the start to new services you add to your canvas.

Connecting Services

Each service has white circles surrounding it which are its connector nodes. They can be clicked and dragged to create connector arrows.

Two services can be connected by connecting the connector nodes between the two.

Most services can have only one outbound connection. The Exception to this is a Binary Decision. This service can have two outbound connections because it performs a logic test and depending on the outcome takes either the “True” path or the “False” path outward. These are often used in processes because they give the ability to create multiple process branches for all possible cases.

Adding New Services

In order to create a process, you will need to add new services between your “Start” and “Terminate”. On the left side of the Process screen you have a list of all services. They are divided into Workshops which describe their use. In order to find a particular service, you first need to find the corresponding Workshop. For instance, if you wanted a service to tell you the current date or time, you would look in the “Date and Time Services” Workshop. If you wish to query a database, you would expand the “Database Services” Workshop.

After finding the desired service, it can be added to the process canvas by selecting the service and dragging and dropping onto the canvas.

Some workshops, like the “Database Services” Workshop, have some further options available for each Service. If you expand the Inquire service, you will see some options related to the saved database configurations. Selecting one of the Database Configurations under the service instead of the service level to drag in, will auto fill some service properties.

In our Inquire example, dragging the AppData configuration to the process canvas auto fills the DbType and ConnectionString properties with the AppData variables.

Renaming Services

Selecting a service on canvas and going to the properties tab on the bottom right will let you rename it. Assigning meaningful names to services greatly improves the readability of a process.

Services should be named when they are first placed on the canvas because the name is referenced by other services on the canvas. If you wait until your process flow is fully developed to rename services, it will break your process flow logic because it will reference an old name which no longer exists.

The name of a service cannot contain spaces.

Create ForEach Loop

A ForEach loop allows us to iterate on the results of previous service in the process canvas. The ForEach service can be dragged onto the process canvas from within the “Process Flow Elements” Workshop, but creating it through the top menu option auto fills the input parameter “SelectorValue” for the selected service. This is the only input parameter to the service. It is the node we wish to iterate on.

Creating the ForEach from the right-click menu also creates both the begin and end ForEach services since these must be used in pairs. It also auto names the services based on the SelectorValue. If we look inside the begin ForEach service, we can see the SelectorValue auto-filled.
