![]() ![]() the entire table) under ALL(), we avoid duplicating all the detail above each subtotal row. It accounts for the group Order field in our underlying Query, that is required in Power BI but not in Power Pivot.Ģ. Otherwise there is nothing in the fact table to evaluate to our custom subtotals, and the subtotal names would be skipped in the matrix.Īlso note that we include two columns in our ALL function here (GroupOrder and GroupName). When in a subtotal row, this number is used below to define and filter the range in the subtotal expression.ģ – Sets up the subtotal expression when flag = 1 by summing the full range in the fact table where Group Order numbers (defined in 2) are less than the current row.Ĥ – It is important to note here that the only reason that our self defined subtotals appear at all in the matrix, is due to the FILTER ALL table expression that overwrites all group names found in the dimAccounts table, including Margin and Margin Less Payroll. When the evaluation matches a flag row equal to 1, the subtotal expression kicks in, otherwise the default SUM expression is used.ġ – Identifies each subtotal row in the dimAccount table that contains a max value of 1, and is used to activate the subtotal expression.Ģ – Identifies the current Group Order number in our dim Accounts table. When we write the subtotal measure, we look to a variable called Flag to define each unique subtotal row in the dimAccounts table. The main driver for cascading subtotals is the use of a flag column in the account dimension table. ![]() ![]() To learn more about the impact in Power BI, and the simple fix, check out this new video from our friends at SQLBI. Basically, the Power BI version of the query includes the ‘sort by column’ in the underlying query, where the same query in Power Pivot does not. The need to modify this for the sort order stems from a difference in the underlying query in Power BI vs. I also combine multiple expressions into one measure with the help of DAX variables. I’ve modified it slightly to work with sorted dimension columns in Power BI (defined above). The first subtotal method is cascading subtotals, and goes way back to a 2011 Power Pivot Pro post by David Churchward here. ![]()
