Auto Remove Followers From Closed Opportunity

In Salesforce a user can follow Chatter groups or Records. The chatter group manager can add/remove peoples to the group, for this Salesforce provides out-of-the box functionality. To manage record follower/SubscriberSalesforce does not have any inbuilt functionality like to create few rule for auto Follow or Unfollow records. OnChatter a user can follow maximum a of 500 Peoples, topics, and records. To effectively manage Chatter, an organization has to use some App to auto unfollow records.

Business Use case :- Higher management in Universal Container wants to develop an app, so when an Opportunity is updated with Closed-Won/Closed-Lost all followers will automatically remove.

Solution of above business requirement

I think this is a good use case to start with Headless flow. After Summer’14 release sObject variables, sObject collection variables, and loops in a flow will be generally available. To solve this requirement we will use Visual Workflow, Workflow rule to fire Flow Trigger. Before going ahead with the solution you have to understand aboutEntitySubscription Object. It’s Represents a subscription for a user following a record or another user. User can subscribe to a record or to another user.

Field Name	Details
ParentId	ID of the record or user which the user is following
SubscriberId	ID of the User who is following the record or user

To develop this application follow the below instructions

Click on Name | Setup | App Setup | Create | Workflows & Approvals | Flows
Click on New Flow, it will open flow canvas for you
First create a variable with name OppID and we will use into the flow, From Workflow we will pass the Opportunity ID into this variable
Drag and drop a Fast Lookup( Give the name Find all Followers ID) on the window
- Select Object EntitySubscription
- Enter criteria ParentId= {!OppID.Id}
- Save ID in Sobject Collection variable in my case it’s {!OppSubcribersID},same like below screenshot

To Get all EntitySubscription ID for Closed Opp

Based on the Sobject Collection {!OppSubcribersID} we will decide Visual Workflow next action. Now add one Decision element to decide whether closed opportunity has any follower or not based on that it will perform the necessary action. If Sobject Collection variable {!OppSubcribersID} not equal to null it means record have some followers. You can take help from below screenshot to create Decisionelement

Decide What to do Next Remove follower or do nothing

The next task is to delete all followers from opportunity record. To do that Drag and drop a Fast Delete( Give the name Remove Subscribers) onto the window, and select Sobject Collection variable{!OppSubcribersID}, as shown in the below screenshot

You have to add some action for default Decision action what happen If an Opportunity doesn’t have any followers. I used Assignment Logic because if an Opportunity doesn’t have any followers I don’t want to perform any action. You can take help from below screenshot

Finally our flow will look like the below screenshot

Auto Remove Followers From Closed Opportunity

Save the flow with name (Remove Followers From Closed Opp) and close the canvas.

Create Workflow rule to fire our Flow

Our next task is to create a workflow on the Opportunity object on creation and every time it’s edited event. To create a workflow on the Opportunity object follow the below instructions

1) Click on Name | Setup | App Setup | Create | Workflows & Approvals | New Rule
2) Select object Opportunity from the drop-down
3) Enter Name, for Evaluate the rule when a record is select created, and every time it’s edited, For Rule Criteriaselect is Stage= Closed Won,Closed Lost, as shown in the below screenshot

Workflow Rule on Opportunity Won or Lost

4) Add one Immediate Workflow Actions i.e. New Flow Trigger and Select Flow and set Variable (OppID) value as shown in the below screenshot
