Chatter Topics helps you to associate your updates with other posts and comments on the same topic by using a hashtag (#). By using hashtags, you create a topic link that categorizes your update so other users in your company can find it more easily. You can also use Chatter Search to find updates and comments that match the Chatter Topic you are looking for. Now I am coming to the point way to delete Topics in Salesforce. In Salesforce document it’s mentioned People with the “Modify All Data” or “Delete Topics” permission can delete topics using the Chatter API or the SOAP API. Another way to delete Topics is using Developer console or Workbench.
Business Use Case
Higher management at Universal Containers wants to develop an application, from where they can easily delete Topics. Their system administrator frustrated from the old way from where every time they have to query to delete topics by using Developer console or Workbench.
Solution for the above business requirement
Again this is the power of Visual Workflow, we will create an app without using a single line of code. Our app starts with a screen where the user can enter topic he/she want to delete, as soon as he/she can delete next topic will delete from Salesforce. To develop additional functionality 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
- Drag and drop a Screen ( Give the name Enter Topic) on the window, add one field ( Give the name Enter Topic Name) and make it required as shown in below screenshot
- The next work is deleting entered topics. Before going ahead you have to understand about Topics Object. It represents a topic on a Chatter post or record.
- Drag and drop a Record Delete ( Give the name Delete Topic) on the window. Under object select Topic, and Map Name –> Input field from last screen. as shown in below screenshot
- Finally, our flow will look like below screenshot
- Save the flow and close the canvas.
Add Visual workflow into the home page component
We can call flow from custom button, link, sub-flow, Visualforce page. Here we will call our flow from the home page component. To do that follow below instruction
- Create custom link from Name | Setup | App Setup | Customize | Home | Custom Link
- Add custom link in the Home page component
- Add Home page component into the Home page layout
It’s time to test this feature
Now we will delete Chatter Topics through our app. Currently I have three topics in my Org you can see below screenshot.
Open our app and enter Topics that you want to delete. In my case I am going to delete Topics chr and click on the Next, as shown in below screenshot
Now check Topics, as shown in below screenshot
Note: – When deleting topics, consider below points
- Topics are hard deleted. They aren’t sent to the Recycle Bin.
- Deleted topics are removed from search results, the topics list, all posts and records, Recently Talked About topics, Related Topics, and your users’ favorites. Deleted topics are removed from Trending Topics after the next calculation.
- Deleted topics are not blacklisted. Users can reintroduce a topic after it’s been deleted.
