 Lead Time Satisfaction for External Dependencies

For checking the status of external tasks, the period that should be taken into account must be specified. The External Dependency tab contains a selection of settings which can be considered for calculating the lead time satisfaction.

The lead time satisfaction is the particular time span in which the external task ends at least once or during which a timeout occurs.

The external task's activation of start time is irrelevant. What's important is its end time. If this end time does not lie within the satisfaction lead time, further processing depends on the settings made in the external dependency. You can either wait for the external task to end, skip the external dependency or cancel the workflow.

The following intends to illustrate the different durations of lead time satisfaction. The involved workflow consists of two tasks and one external dependency.

Since last Workflow Execution

The lead time satisfaction commences when the last workflow execution ends.

 

Within a Time Span before Workflow Start

The lead time satisfaction commences before the workflow starts. How far back this time span dates depends on the specified value.

The lead time satisfaction is limited if the end of the last workflow execution lies within this time span.

After Workflow Start

The lead time satisfaction commences when the workflow starts.
