You configure refinement statistics for regular (non-aggregated) records in Developer Studio.
To configure dimensions for refinement statistics:
Only the configured dimensions will be considered for computation of dynamic dimension value statistics by the Oracle Commerce MDEX Engine.
To enable refinement statistics for aggregated records (that is, those
records that are rolled up into a single record for display purposes), use the
--stat-abins
flag with the dgraph. You cannot
enable refinement statistics for aggregated records using Developer Studio.
