Several additional VLDB properties are introduced with Strategy 9.x. One of the options under Analytical Engine folder is called "Metric Level Determination." The default value here is "Include only lowest-level attribute in metric level (recommended for version 9.0 and higher).
The second option, "Include higher-level related attribute in metric level (deprecated)" should be used only when the report is affected by the issue discussed in following tech note:
KB417446 - Some metric values are repeated across rows when a report is executed in Strategy
This option is provided when the end goal is to adjust the schema design as explained in above Knowledge Base article.
More detailed explanation for this option can be found at:
System Administration Guide Vol. 1 > A. SQL Generation and Data Processing: VLDB Properties > Details for all VLDB properties > Displaying, evaluating, and ordering data: Analytical Engine > Metric Level Determination.
