If you are using preconditions with a JSU post function, they can be evaluated in the following ways:
Ignore precondition (default): Every precondition is ignored which means that the post function will always be performed
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 ‘Ignore’ by default. You can learn more about our preconditions in Workflow Preconditions.
