There is now a Webel trail on how to handle specific Derived Property cases!

About the EXTERNAL links

Links to external resources are provided by Webel IT Australia without any guarantees concerning their accuracy or suitability for practical SysML/MBSE

This list of external links is primarily to assist in extraction of model information into query view tables (such as for Derived Properties shown in a column of a Generic Table Diagram) for trickier cases where the Simple Navigation and Metachain Navigation are not enough.

There are lots of little "gotchas" when working with these features, and it may take some patience and trial and error getting things to work as expected. For example:

If you can successfully extract some model information using a script and you can see that in the Evaluation Mode in the expression editor it still might not appear in a column in the Generic Table Diagram because it can only display certain types

If you want to reuse an OpaqueBehavior in other derived properties or structured expressions there are rules for making it executable and for making it place nicely with wider derived relations mechanism.

If you are completely new to the topic, these slides may help:

There are some long sessions videos for the above as well as many videos by other authors. The quality of the videos linked below varies greatly; some only cover specific aspects, some jump around a lot during the presentation, so if you are looking for guidance on a specific model info extraction wading through the videos is mostly very time consuming. Mostly, slides and help page docs are the best resources.

The video series by the Systems Architecture Guild has some nice shorter videos that show how to achieve specific extractions:
