Hello Friends,

In this post, we will go through a step-by-step example of using Fork to implement parallel processing in a Workflow. In our example we will have a Multiline Container Element where user can finish a task just by displaying a Material.

Steps for designing your Workflow:

    1.    Go to the Transaction SWDD – Workflow Builder. You will be presented with a screen as shown in Figure 1 below else you may create a new Workflow using Menu Bar → Workflow → New (Ctrl + Shift + F5).

Testing your Workflow


    1.    Provide input values for a Valid Material by following the Steps as shown in Figure 10. We should enter more than one material here.

In this example we will use 2 materials. So enter one more valid Material in the Input Data.

    2.    Go to Menu Bar → Workflow → Test (F8). You will get a Success Message in the Message Area of your Screen with text similar to Task started under work item ID <xxxx> (current status: In Process)

    3.    Go to Menu Bar →Environment → Business Workplace (Shift + F6). Check the Workflow Folder in the Inbox Folder. You can see two new items in your Workflow Folder as shown in Figure 11 for 2 Material that you have entered in the Input Data for testing. Clicking on any item will process one parallel branch of the Workflow by showing one Material.

    4.    After you have displayed the material you can see only row item is remaining. If you click this remaining item, it will show the other material that you have entered.

You can also see your Inbox for notification. Note there is only a single notification.

Now you can press the Back (F3) Button to go to the Test Screen of your Workflow.

    5.    Go to Menu Bar → Goto → Workflow Log (F5). As shown in Figure 14, you can see that the Status of a Workflow Item is Logically Deleted.
