    Hi @ZengDingding ,

    You can control the number of aggregations the wizard designs by one of the following methods available in the wizard:

    • Specify a storage space limit for the aggregations.
    • Specify a performance gain limit.
    • Stop the wizard manually when the displayed performance versus size curve starts to level off at an acceptable performance gain.
    • Choose not to design aggregations.
      SSAS will use the combination of heuristics and dimensions properties to decide for which dimension attributes aggregations should be build. For more info, check out Aggregations and Aggregation Designs

    First, you don't usually create an aggregation based on a single query.
    When deciding which attributes to base the aggregation on, you need to take attribute relationships into consideration. Basically an aggregation is a copy of a fact table but at a lower granularity. So for each dimension, you see how far up from the key attribute you can go so that your query is still covered. E.g. for a query referencing months and quarters you include the month attribute in the aggregation, provided there's the usual relationship where months group into quarters.
