Please Explain,
what I’m missing here?

I’m trying to create View filters from already Created Duct Systems.
but I’m not able to set the rule for these filters.

Note - My Goal is first create System Types & Then Create View Filters (without assigning systems to elements at start)

Need to show the errors being returned in order to address. You could try using the ParameterFilterElement.ByRules node instead.

The error is more than likely being caused by one of the categories not having the parameter “Abbreviation” assigned to it.

Couple of things. You only need to feed one instance of the parameter into the FilterRule.ByRuleType node. Also, instead of using “Equals”, you could use “BeginsWith” for the rule type and set the filterby value to “AHU”. If that will work for you.
