Overview

This mini - process gives a brief overview of the design of a process with low code.

The process consists of two sequential tasks, named 'ping' and 'pong'. A requester addresses somebody in the start form to support him in his work on a document. The supporter recipient gets the 'ping' task in his inbox and has a look at the document, . He then gives an answer and forwards the task back to the requester. The requester gets the 'pong' task in his inbox, reads the answer and forwards the process to its end.

The following sections explain the minimal coding needed for the process.

This process, which reads the answer to a question, is one of the smallest you can design.

...

You need three things to get started:

• A working system, version of enaio® redline version 4 or later
• A usable scenario of object types, such as one of these.
• The project file containing the process definition described below (click to download).

system

• Unzip the project file (see Requirements) to the Documents folder.
• Start enaio® yuuvis® designer.
  • Click Open.
  • Navigate to the folder where the scenario was unzipped. Select the .eoproj file and confirm the selection with Open.
  • Open Process models in the navigation tree of the project.
  • Copy Ping-Pong in the navigation tree by right-clicking and then pasting it into the Process model of your deployed project.
  • Deploy Ping-Pong to your enaio® system by right-clicking the process model and selecting Deploy. 
• In a browser (Firefox, Chrome, or Edge), open enaio® yuuvis® management-studio at <servername>/enaio/management and log in with your administrator account.
  • Go to main to Main menu > Processes.
  • In Process Management, select register Models.
  • In the In-tray on the left, select Ping-Pong.
  • Click the action the Actions menu on the right and select Move. Specify where in the Model groups to move to.
  • Click the action the Actions menu again and select Activate.
• In a browser, open enaio® yuuvis® client and select any object.
  
  • Click the action the Actions menu on the right. Under More actions, you will see Start mini-process Ping-Pong.
  • How to use the process see below

Process Model

Start enaio® yuuvis® designer.

• Open a project.
• Right-click on Process models in the navigation tree and select New process model. Give Enter a name, here Ping-Pong, and a namespace, here Examples.
  Now you can begin to define your process model by setting configuring tasks in the working area (middle area) and setting defining the attributes for each artifact (area on the right). 
• Define the general attributes of the process model:
  • For each language, enter a Name for starting the process. The Name is displayed in the client object action actions menu in More actions.
  • Optional: enter a Description to be displayed in the Information for the action.
  • In the client view My processes, select a role for Initiators (those who can start the process) and Process owners (those who can monitor the process). Here, System-User-Role was used for the initiators and System-Admin-Role for the process owners.
  • Check Show start form to display the form after the start action in the client has been selected.
  • Check Process start with main object to display the start action for each object with Main object type = ' ' and Main object type = Any.
  • Set some Data fields, here we use:
    answer (string), set by supporter (ID-User/Group)
    question (string), set by requester(ID-User/Group)
    subject (string), set with object title from the start form script, see below.
  • Set Subject with {var:subject}.
  • Define Start form with a script.
    
    Figure 3: Start form design and preview
    
    
    Figure 4: Start form script
    
    
• Set the 'ping' and 'pong' tasks in the work area.
  • Click the Work item tool in the application bar, then . Then left-click in the work area where you want to place and span the task shape, and release the mouse.
    Give Enter the Technical name, here ping, to be used in event scripts.
    Give Enter the Name, here Ping support: answer question, to be shown in the client Inbox list.
  • Repeat the last two steps for the 'Pong' task.
    Give Enter the Technical name, here pong.
    Give Enter the Name, here Pong answer: Read support message.
  • Connect the tasks by clicking the 'ping' task, then moving . Then move the cursor over the right edge of the task shape until a small rectangle appears. Click the rectangle, then move the to the pong-task shape and release.

• Define Ping Task Attributes
  • Select the 'ping' task.
    
    
    Figure 6: designer work area with 'ping' task selected and its attributes displayed
    
    

  • Set Participant type to "Script-controlled", then write the BeforeStartActivity script to define the participant (performer).
    
    

    Code Block
    language js title BeforeStartEvent Script
    // defined supporter becomes performer var newPerformer = new $.OrgObject(); newPerformer.id = $.variable('supporter').value; $.activity('this').performers.push(newPerformer); $.done();

If Ping-Pong is deployed in the configuration as described above, each user can start a process for any object available to himthem.

• Start a process in the client
  • Select any object.
  • Click the action the Actions menu on the right and, in the section More actions, select Start mini-process Ping Pong.
  • The following fields in the start form must be filled in:
    The Subject is preset with the title of the object and can be modified.
    Type your Question.
    Define the Supporter by typing '*' to get a list of all users, or start typing the first or last name to open a suggestion list.
  • Click OK to start the process.
• Ping Task: Answer question
  • Open the Inbox
  • Select the task and click Accept task to show the task form
  • Read the Question and write your Answer
  • Click Forward to forward the process to the Pong task
• Pong Task: Read supporter's Answer
  • Open the Inbox
  • Select the task and click  Take over to show the task form
  • Read the Answer
  • Click Forward to continue the process to its end
• Monitor the process
  • Each process initiator and process owner can monitor processes in the view My processes.
    Go to main to Main menu > My processes and have a look at the process history.
    
    

Ideas for

...

Extensions

• Rename the Forward actions
  • Configure a task action Return for Ping and Finish for Pong instead of showing standard Forward
• Deadline
  • Fix Fixed deadline
    Can be configured without scripting in process aspect Time periods.
  • Flexible deadline
    Add a datetime field deadline to the process and add this onto the forms as well. The user may specify a deadline. This predefined deadline has to be set by a next short scripting.
• Repeat the Ping-Pong
  • Use a Loop - Task arround  around the Ping and Pong tasks and control it by an additional Boolean field repeat which can be checked on the Pong task form.
  • Use a string field communication and store each question and answer to it using the BeforeEndActivity event script. Add this to the Ping and Pong tasks as well.
• Constrain the possible supporters
  • Set a filter for the ID field as described here.
