SCENARIO:

Is there a simple way to insert the process flow log(summary) in a text file rather than sending it as an email with Notification Type as Process Flow Summary in an Mail Notification service? 

SOLUTION:

This can be achieved by below steps:

1. Create a Custom plugin that will get the process flow details. We have attached the custom plugin.

2. Then create a Mail Target Activity.

3. Now use the Mail Target Activity after this custom plugin in your process flow.

For more information about the custom plugin refer the Developer Guide(Creating Extensions>>Creating Custom Plugin Activity).
