Before going ahead let us review the aforementioned known issue again – Process Builder updates Task – WhoId field only through inline edit but not through normal edit. This mainly applies to Org where – Allow Users to Relate Multiple Contacts to Tasks and Events – feature is enabled.

In light of the above-known issue framework, let us now look at a business case.

Edward Backhouse is working as System administrator at GurukulOnCloud. At GurukulOnCloud they are using Mircosoft Office 365 as their email client. Using Third-party applications they are syncing Salesforce – Microsoft Outlook calendar. They have enabled, Allow Users to Relate Multiple Contacts to Tasks and Events feature in Salesforce. 

Edwards created a process in the past to update WhoId/NameID to null (similar to what is explained in the Salesforce known issue) when Subject contains a word Outlook, but because of the above-known issue, it is no longer working. 

A solution for the above business requirement

There are few possible solutions for the above business scenario – at least two as per my understanding. The first solution will look like the following screenshot: 

The above solution will work in the most cases but, in my case, it did not work in all scenarios. So I used the second solution, which I am going to explain in the article – How to add time-dependent action to a Process which Start when a record is created or edited and advanced option checkbox is not selected.

Before we proceed further, let us understand the characteristics of a TaskRelation Object. It represents a person (a user, lead, or contact) or a resource (such as a conference room) invited to a task.

1. Navigate to Setup (Gear Icon) | Setup | PLATFORM TOOLS | Process Automation | Flows. Click on the New Flow button; it will open the Flow canvas for you. Create variables in the Flow, as shown in the following table:
   

   Name	Variable type	Object type	Input/Output type
   VarTTaskId	Text	Not applicable	Input and Output

2. Now we will use the Wait element to create time-dependent action, as shown in the following screenshot: 
3. Once you are done, click on OK button. 
4. The next step is to use a Record Delete element to remove WhoId/NameID. Drag-and-drop Record Delete element to delete all records associated to a Task through WhoId, as shown in the following screenshot: 
5. Once you are done, click on OK button. 
6. Use connectors to connect the elements used in the Flow. Finally, your Flow will look like the following screenshot:
7. Once done, Save the flow and name it Clear WhoId, with Type: Autolaunched Flow. Do not forget to activate the Flow by clicking on the Activate button.
8. The next step is to create a process, that will fire when a task subject contains a word – Outlook. To do this, Navigate to Setup (Gear Icon) | Setup | Process Automation | Process Builder
9. To create a new process from scratch, click on the New Button available on Process Management page. A popup will appear where you have to enter the Name (Use Clear WhoId Process as the name), API Name and Description as shown in the screenshot below:
   
10. Once you are done, click on the Save button.
11. Click on the Object node to add object and then select the Task object. For the entry criteria, select when a record is created or edited, as shown in the screenshot below:
    
12. Once you are done, click on the Save button.
13. The next task is to add Process Criteria, so that process will only fire when it meets the stated criteria. To do this click on Add Criteria, enter Name, Type of action and set filter conditions, follow the following screenshot for details:
14. Once you are done, click on the Save button.
15. Now we have to add an Immediate action to the Process to update account record. Click on Add Action (Under Immediate actions), Select the type of action (In our case Flows), and then fill the values into fields to define the action – as shown in the following screenshot:
    
16. Once you are done, click on the Save button. 
17. In the end, your Process will look like the following screenshot:
    
18. Do not forget to activate the Process by clicking on the Activate button.

P.S.:- The only part missing in this flow is to check TaskRelation record before deleting it. I removed those parts from this article to keep it brief.

It’s time to test this feature
