The combined table resulting from this filter only contains columns explicitly listed in SUMMARIZECOLUMNS as grouping columns or filter columns. The CALCULATE function in DAX measures; Removing filters in an expression using CALCULATE (this blog) Using the CALCULATE function to replace filters The FILTER function in DAX allows you to iterate down the rows of any table, creating a row context for each and testing whether the row should be included in your calculation. name: The name given to a total or summarize column, enclosed in double quotes. Any filter applied in DAX, say in a CALCULATE, was considered an 'inner' filter. I want to know who has the highest per unit average and regardless of what the FI-Manager context it will always show this highest per unit average (of all FI-Managers). To summarize: A row context is not filtering the model in any way. In DAX there's no way to create a string dynamically and execute it (like in SQL, for example). Filter context filters, row context … Client tools like Excel and Power BI almost always generate context transitions to evaluate measures in the reports. If one wants to apply a filter to the model, then we use the filter context. And this feature is the basis for the dynamic behavior you're talking about. This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules. Best regards, Konstantin Mainly there are two types of context in DAX, ... Filter context is the set of values allowed in each column, based on filter constraints that were applied to the row or that are defined by filter expressions within the formula. In the case of row-level calculation, we use the row context. Hi, I'm brand new on PowerBi, I have 3 facts and I need to get the % of comparison to the previous year. Doing a calculated table using "summarize" like below is fine, but totals do not change in the context of the filters against the raw data table. However, I need the "Group By" action of SUMMARIZE. But before, how would I need to alter my error-prone DAX statement in order to get - per itemno - the Min and Max - values from the "BaseTable"?

Thanks for your response. I'm not sure I put it right in the question. You can combine filters using keywords like AND and OR and also nest one filter within another. Am I wrong? Any DAX expression that returns a table of data.
