Hi Donald,
We will aim to introduce support for run property groups in a future release in a few month's time.
The run property values are constants for a data flow execution and cannot be modified from within the data flow (i.e. they are not global/environment variables).
The relevant sections of the documentation are:
- Advanced topics -> Defining properties
- Advanced topics -> Using derived property values
As an alternative, if you are using scheduled execution of the data flows using an external scheduler, you may want to consider using the external scheduler to execute a scheduled run via the defined API and pass in the required runtime property values from the external scheduler.
The API documentation is in the following section of the server help:
System administration -> API developer documentation
(See Ad-hoc run of a simple scheduled task)
Regards,
Adrian
