If you are using preconditions with a JSU post function, they can be evaluated in the following ways:
True (Precondition must be true to execute a post function)
False (Precondition must be false to execute a post function)
The precondition setting is available on our post function configuration pages, and it is set to True by default. You can learn more about our preconditions in Workflow Preconditions. See the Preconditions for Post Functions uses cases for examples.
