Big Idea or Enduring Question:

How do you provide a way for deleting the Chatter group feed to the key users? 

Chatter Group is primarily geared towards boosting collaboration among users within an organization. Similar to a public group, a Chatter group comprises a set of users. Indeed, one can add unlimited users to a Chatter Group.

Some time the Chatter group is very cluttered that as a manager, you want to delete the old post. There are a few apps available on AppExchange for this purpose, but nothing comes out-of-the-box. In this article, we will create automation that allows users to delete a specific type of posts for Chatter groups.

Objectives:

This blog post will help us to understand the following

• Use a Screen a flow to take the user input 
• How to delete the records using the delete records element 
• Understand how to create a custom permission
• Understand how to use custom permission to hide a component 

Business Use Case

Brenda David is working as a System administrator at Universal Containers (UC). She has received a requirement from the management to create a wizard that allows a set of users to delete posts (created before a specific date) from Chatter groups. 

1. Manual Deletion
2. Lightning Web Component 
3. Apex Code
4. Data Loader

We will use Salesforce Flow to solve it. 

Field Name	Details
ParentId	The Id of a chatter post.
LastModifiedId	It is the date and time when a record was last modified by a User.

Before discussing the solution, let me show you a diagram of a Process Flow at a high level. Please spend a few minutes to go through the following Flow diagram and understand it.

Let’s begin building this automation process.

Guided Practice (We-do):

There are 4 steps to solve Brenda’s business requirement using Screen Flow. We must:

1. Salesforce Flow Steps: (Screen Flow)
   1. Create a text variable to store chatter group id
   2. Add a screen to capture the user data
      1. Add a screen component
      2. Add a Date component 
   3. Add a get record element to find collaboration group feeds created before a given date
   4. Add a decision element to check the record collection variable (from step 1.3)
   5. Add a delete records element to delete chatter posts
2. Creating a custom permission
3. Assign custom permission to the system administrator profile  
4. Add flow to the chatter group page and add filter criteria 

Step 1.1: Salesforce Flow – Create a Text Variable to Store Chatter Group Id

The Screen flow which we are creating will be used in the Chatter group Page to delete posts. 

1. Click Setup.
2. In the Quick Find box, type Flows.
3. Select Flows then click on the New Flow.
4. Select the Screen Flow option and click on Next and configure the flow as follows: 
   1. How do you want to start building: Freeform
5. Under Toolbox, select Manager. Click on the New Resource. 
6. Input the following information:
   1. Resource Type: Variable
   2. API Name: varTCollaborationGroupId
   3. Data Type: Text
   4. Default Value: {!$GlobalConstant.EmptyString}
   5. Check Available for Input
   6. Check Available for Output
7. Click Done. 

Step 1.2.1: Salesforce Flow – Add a Screen Element 

1. Under Toolbox, select Elements. Drag and drop Screen onto the canvas. 
2. Input the following information:
   1. Enter Label the API Name will auto-populate.
3. Click Done. 

Step 1.2.2: Add a Date Component to Allow Users the Enter Date to Delete Past Chater Posts 

1. Under Input section on Screen Element. Drag and drop Date onto the screen. 
2. Input the following information:
   1. Enter API Name.
   2. Label: Enter Date
   3. The API Name will auto-populate
   4. Require: True 
3. Click Done.

Step 1.3: Salesforce Flow – Adding a Get Record Element to Find Collaboration Group Feeds Created Before a Given Date

1. Under Toolbox, select Element. 
2. Drag-and-drop Get Records element onto the Flow designer. 
3. Enter a name in the Label field; the API Name will auto-populate.
4. Select the Record CollaborationGroupFeed object from the dropdown list.
5. Select All Conditions Are Met (AND).
6. Set Filter Conditions
   1. Row 1:
      1. Field: ParentId
      2. Operator: Equals
      3. Value: {!varTCollaborationGroupId}
   2. Click Add Condition
   3. Row 2:
      1. Field: LastModifiedDate
      2. Operator: Less Than or Equal
      3. Value: {!Enter_Date}
7. How Many Records to Store:
   1. select All record
8. How to Store Record Data:
   1. Choose the option to Automatically store all fields. 
9. Click Done.

Step 1.4: Salesforce Flow – Using Decision Element to Check the Record Collection Variable (from step 1.3)

Now we will use the Decision element to check the Record Collection Variable from step 1.3 to find if it returns the record(s) or not. 

1. Under Toolbox, select Element. 
2. Drag-and-drop Decision element onto the Flow designer. 
3. Enter a name in the Label field; the API Name will auto-populate.
4. Under Outcome Details, enter the Label the API Name will auto-populate.
5. Condition Requirements to Execute Outcome: All Conditions Are Met (AND)
   1. Row 1:
      1. Resource: {!Find_Feeds}
      2. Operator: Is Null 
      3. Value: {!$GlobalConstant.True}
6. Click Done.

Step 1.5: Salesforce Flow – Delete Records – Delete Chatter Group Posts

The next step is to add a logged-In user to the chatter group. We will use the Create Records element. 

1. Under Toolbox, select Elements. Drag and drop Create Records onto the canvas. 
2. Input the following information:
   1. Enter Label the API Name will auto-populate.
   2. How Many Records to Create: One
   3. How to Set the Record Fields: Use the IDs stored in a record variable or record collection variable
   4. Select Record(s) to Delete
      1. Record or Record Collection: {!Find_Feeds}
3. Click Done.

In the end, Brenda’s Flow will look like the following screenshot:

Once everything looks good, perform the steps below: 

1. Click Save.
2. Enter Flow Label the API Name will auto-populate.
3. Click Show Advanced.
4. Type: Screen Flow
5. API Version for Running the Flow: 51
6. Interview Label: Clean Chatter Group {!$Flow.CurrentDateTime}
7. Click Save. 

Almost there! Once everything looks good, click the Activate button.
