Creating a task chain

You can chain your tasks in just any pattern. This example describes how to create a task chain that reloads the data in three different apps, but task chaining is also available for external program tasks and distribution tasks.

• Task 1 reloads app A, every hour.
• Task 2 reloads app B, daily.
• Task 3 reloads app C, if Task 1 and Task 2 is executed within 120 minutes.

Do the following:

1. Create a new reload task for app A:
