Run Always vs. Triggered Items
In the Transaction Group workspace, you can set the Expression items in a group to execute in two different ways:
- Run-Always in which the Expression items will execute at the groups rate (based on the Execution Scheduling settings on the Action tab).
- Triggered in which the Expression items run when the group is triggered (based on the settings on the Trigger tab).
If on the Trigger tab, the option Execute this group on a trigger is not selected, the items in the Run-Always Expression Item area and Triggered Expression Items area will all execute at the same time. The advantage selecting the Execute this group on a trigger option is that is gives you flexibility on when the expression items are executed which may result in easing the load on a database.
