Hi all, 

extract run for payroll integration stopped. we need to understand why, and reschedule.

How I can see the configuration of the schedule to understand if an end date was entered?

Once I reschedule the run I need to enter "Frequency". How can I understand which one was used in the scheduled run that stopped to work?

Thanks 

Nicola
