It’s much different than it looks. You give SUMX a table of data that tells SUMX how often you want to evaluate an expression. If you want to filter the values that you are summing, you can use the SUMX function and specify an expression to sum over. I started by replacing the SUMX with a calculate. It goes through a table, row by row to complete the evaluation after filter is applied. SumX then sums each result of all of the iterations of that expression. 4 times faster, scaling on all the available cores. You'll find some data samples of both tables here below and the measure definition. » Read more. SUMX returns the sum of an expression evaluated for each row in a table.

I attempted to implement a DAX expression that "weights" the 6oz_pct relative to the proportion of the report number's [First_Net] vs. the sum of [First_Net] for the [Related.FieldID] in the specific [Crop.Year]. The calulcate doesn’t loop through every row but rather filters the dataset.

The SUMX will create a copy of the filtered table and loop through it and evaluate every row and only sum the values that are true. There is no relationship between both tables in the model. DAX X vs No-X Functions. While the result of the # Customers SUMX measure is identical to that of # Customers, the request sent to the DAX engine is different: now there is an expression to compute for each unique value in Sales[CustomerKey]. because an iterator function goes through every row and apply the transformation, then the result is materialized (temporary) before aggregating it, and that causes the totals to be actual sum (or other aggregations) of values in a column. You can use SUMX function. DAX will go row by row, down the sales table.
