Problem

I import orders via CSV and want them to be more regularly imported than every hour.

Solution

To schedule an import to run every 15 minutes, you will need to create 4 separate schedules in one import configuration. Each schedule needs to be configured to occur every 1 hour with the Starting times being set at the required minutes. The end times can be set for all as the latest runtime suitable for you. 

For example for 24-hour runtimes:

Schedule 1 - occurs every 1 hour - Starting time 00:00, Ending time 23:55

Schedule 2 - occurs every 1 hour - Starting time 00:15, Ending time 23:55

Schedule 3 - occurs every 1 hour - Starting time 00:30, Ending time 23:55

Schedule 4 - occurs every 1 hour - Starting time 00:45, Ending time 23:55
