Use the Activity-End method to cause the system to End the current activity and all calling activities.
Ex: if Alpha calls Beta, which calls Gamma, which calls Delta, which performs the Activity-End method, all four activities are ended.

16. What is the difference between Call and Branch?

The Call instruction calls another specified activity and executes it. When that activity completes, control returns to the calling activity. Use the Branch instruction to find another specified activity and branch to it without a return. When the system executes a Branch step, control transfers to another activity found through rule resolution. Execution of the original activity pauses. When the branched activity ends, processing of the current activity also ends. No steps after the Branch step are executed.
