Advocate ISSAS - Dimension does not aggregate in Power BI Desktop
Hello Community,
i've got a problem with dimensional aggregation using a tabular model in SSAS. I have a star-schema, where fact is linked to serveral dimensions. The lowest level of time is Month ( linked to DIM via Month_ID). Now when calculating the sum for costs in several years the timedimension is not aggregating for example years. PBI doubles years for any month in filtercontext:
I never experienced something like that with other models of SSAS tabular. When searching the cube in SSMS AS and do the same query, it is aggregating years. Any suggestions?
Edit: I think any aggregation of dimensional values in this model behave this way...
SQL Analysis Server 13.0.5026.0
model level of compatibility: 1200
Hello v-juanli-msft ,
the measure is defined by DAX (sum) in SSAS but its not the problem here. In the meantime I got a solution. The problem was the set sorting of Month and Year. It was sorted by day_ID, which meant that although the day is not on the report, each item is still calculated separately by day. I have now arranged the sort on the basis of fields of the same level, which solved the problem.
Nevertheless thanks for your will to help

Hi Xriz
Is the "sum_CO_IST" measure created in Power BI or in SSAS?
How do you define it with DAX or MDX?
Best Regards
