I have an element that shows 2 data tables:

1. Parent table PID 1000
2. Child table PID 2000 with a FK column PID 2004 pointing to the Parent table

I would like to have a column in the parent table showing the most severe alarm level of all the child rows.
How do I do this?

The AlarmLevelLinking featue seems to be for a remote element => data located on a different element.
While I would like to have this for my own element without the need of custom logic retrieving the active alarms.

Note: I need the value in a column for other purposes, so showing treecontrol is not an option.
