Below DAX might be helpful in your case considering you have recorded the No. groupBy_columnName must be either in table or in a related table. This pattern works very well, but it can be further optimized. In the extension columns that GROUPBY introduces, a new function called CURRENTGROUP can be utilized inside aggregation functions. When you can, it is better to apply a filter using CALCULATE or CALCULATETABLE (see Filtering Data article). SUMMARIZE function Thanks ------------------------------ Daniel Demers A volatile function may return a different result every time you call it, even if you provide the same arguments. Analysts can use the DAX language to come up with new ways to calculate data values and come up with new insights.

The use of COUNT () function in conjunction with GROUP BY is useful for characterizing our data under various groupings. To skip the BLANK value, use the DISTINCTCOUNTNOBLANK function.
