Error when using For Each rule.

DrewB

I'm trying to find a way to loop through all the attributes in a given ruleset. Is this possible?

I've found the "Attributes" collection which, according to the Infor CPQ Design Studio Reference Guide - Cloud Edition, is a read-write collection that contains all persisted component attributes and is probably what I need. The collection is structured as component attribute name and value pairs.

I have a For Each rule (ID: 849) but when attempting to loop through the Attributes collection I get an error "For Each Rule Collection variable must evaluate to a Collection".

So I made a variable rule (ID: 853) and placed it as a parent of the For Each rule. In that variable rule I'm evaluating some expressions to check if the Attributes collection is really a collection, see if a key exists in the collection, and count the number of elements. They all work which indicates that the Attributes collection is a collection, it has a known key, and it has some number of elements (27 in this case).

So why am I receiving an error?

Also, is there any additional documentation besides the "Infor CPQ Design Studio Reference Guide - Cloud Edition"? I'm using the Release 2025.x PDF from October 1, 2025 but I would like more in depth documentation if available.
