There is a common requirement for Resignation approval workflows where the approval is triggered based on a condition by checking whether the worker has completed the probation period or not. The probation end date attribute is not exposed in BPM. So it becomes little tricky to get the probation end date.
In such cases, days between function can be used to calculate the probation end date based on probation period. The pre-requisite is that the probation period for all workers should be entered with UOM as ‘Days’.
Duration.days between(Task.payload.Worker’s Current Assignment.result.Work Relationship Start Date.toGregorianCalendar(),CurrentDate.date) <= Task.payload.Worker’s Current Assignment.result.Probation Period
