Advanced Selection Logic in PTC Windchill

Hi,

just searching for any guide / exercise / demo on how to use the Advanced Selection Logic in PTC Windchill. And I don't mean here working w/ parameters only but actually I mean more - working w/ expressions, case tables, MS Excel support.

Also, where can we find more information about parameters - can their values be precalculated / can their values be transferred to a module attribute value?

Is there anything created over the time?

Thanks.
