Automatic status e-mail notifcation for custom process chain

Hi experts,

We have a custom process chain with two steps.We trigger this process chain based on the events maintained in the SM62 by executing a

custom report.

Now our requirement is to add e-mail notification for this process chain whether it is successful or failure.

It should always trigger an e-mail to the user whether it s failed in any of the steps or it is executed successfully.

We have tried by adding the e-mail alerts as described in the below document but it did not work.

Please let us know is there a way so that this can be achieved.
