To Update Pulse Through Email

In the previous Post we saw how to send email when pulse is posted or user is mentioned in the pulse post.
In this post we will see if we reply to the email, then that content will get attached to the Pulse post and if any documents need to attach to the post that also will get attached.

So For this one Email Listener, Service Email are needed.
Email Listener: To Listen to the Email Inbox or particular folder in the Email. If Any mail comes, then it will triger the Service Email Mentioned in the Listener.

Service Email: To Read the Email and Parse the Email and get the From, To, Subject and the Email Conent. In Pega itself sample Service Email has been given, so no need to change anything directly we can save as to that.

So not only for pulse, for any other email listener approach we can refer this email activity. Example, When we raise Support request in pega PDN Support portal. It will read the Subject and parse the work object and attach the email to the Work Object.

Follow the steps in this url:
https://pdn.pega.com/tutorial-enabling-users-respond-pulse-email-notifications/tutorial-enabling-users-respond-pulse

Example after implementing this steps, we will see how it works.


Got mail from pulse once i had mentioned the user in the post, so user is replying to that post and attaching the document with that email. So that is getting attached to thru the Email listener which we configured earlier.

The received document will get attached to the work object attachemnts as shown below.

Along with that it will get attach to the post to which its replied.

About Pulse Notifications

About Pulse Notifications:

To Get the Notifications when, Pulse messages of Work object are updated, We need to configure as below.

The Details can be get in the below mentioned PDN site:
https://pdn.pega.com/tutorial-configuring-pulse-email-notifications/tutorial-configuring-pulse-email-notifications

Create an email account from which to send notifications by completing the following steps.

1.Click +Create > Integration-Resources > Email Account.
2.In the Account Name field, enter PulseNotifications.

3.Click Create and open.

email Config Screen shot.

Example:
In Our example, in the Case Manager Portal, we created a work Object and Opening the Pulse, and mentioned "@" and refer some name and then write some comment in it. So that user whom mentioned in the message will get email Notification.

About Branch ruleset

Need of Banch Ruleset:

Typically, branches are used in development environments in which multiple teams contribute to a single application. You use branches to develop software in parallel in a version-controlled environment. For example, your teams can develop one feature in a branch while another team develops a feature in a different branch, even if they share the same base rulesets. After feature development completes, you can merge the changes you made for both features into the base ruleset. You can also use branches for providing bug fixes, because you can easily add them to applications.

How to create and use Branch ruleset:
Say below is the application u r going to branch

click Add a Branch Link and add Branch ID. This is required for creating branch ruleset.

After Adding the branch ID, we need to create branch ruleset as below.

Each branch can be used by separate teams, so their works can be separated while developing.

Merging the Branch 2 ruleset and checking.

While merging the Branch ruleset to the main ruleset, all will get added to the Main ruleset.

Note: Check the checkbox, if u want the rules and ruleset back. If its unchecked, then all the rules will get deleted along with the ruleset.

In Branch and main ruleset also having Same rule name, so while merging it will give conflict error.

On click of Conflict, u will get below details:

After resolving the issues, click submit button and merge.
