This page has Planual rules regarding Line Item Subsets that only apply to Classic Hyperblock, as well as shared rules with Polaris (which are also on the Polaris page). Check each rule’s applicability tag to see where it applies.

Rule numbers may skip, since Polaris and Classic Hyperblock share one numbering index.

By default, you should keep summaries turned off on line items using the Collect() function. By having summaries turned on, the system is aggregating data that isn't usually needed.
