Scheduled processing

Since Spring Release 2018 it is possible to schedule processing with better precision.

Rules manager

In the Rules manager the scheduling is set per group. If the group is set to "Only scheduled" or "Normal and scheduled", the group is scheduled and is activated by a time expression. For processing only per schedule, the "Only scheduled" should be set, which will disable event based triggering for the group.

Time expression

The built-in expressions are yearly, monthly, weekly, daily and hourly. In addition to these there is also "Custom", which enables a greater precision. Selecting "Custom" will enable the row showing the expression in cron, which can be adapted to better suit the business requirements.
