Smart Table Analytical Type Highlight Color : Property field

Hi,

I am trying to highlight columns of an analytical Smart Table based on Criticality.

I have set-up RequestAtLeast annotation as well at Presentation Variant, but the colour highlight for column is not working.

Currently in metadata when I check the sap:aggregation-role is showing as "dimension" and below Note in SAP UI5 Documentation says the field that returns the criticality for analytical tables must be a property and not a dimension.

How can I define a field as property?

Thanks,
