Am I wrong? However, I need the "Group By" action of SUMMARIZE. One of the latest addition to DAX has been the ability to apply an external filter context to SUMMARIZECOLUMNS, which makes this function a perfect replacement for SUMMARIZE in DAX. Hi, I'm brand new on PowerBi, I have 3 facts and I need to get the % of comparison to the previous year. Any filter applied in DAX, say in a CALCULATE, was considered an 'inner' filter. This blog shows you how to use it to replace, remove and amend the query context for a measure (and also explains what this sentence means!). Best regards, Konstantin 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. It only tells the DAX which row to use from the table. DAX query Thanks for your response. 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). This parameter cannot be an expression. From what I know, because of using an expression inside the "Base Table", data linage is lost and thus, the row context from the 2nd ADDCOLUMNS is rather uneffective. 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. The CALCULATE function in DAX measures; Removing filters in an expression using CALCULATE (this blog) Using the CALCULATE function to replace filters I'm not sure I put it right in the question. groupBy_ColumnName (Optional) The qualified name of an existing column used to create summary groups based on the values found in it. If one wants to apply a filter to the model, then we use the filter context.

REMOVEFILTERS can only be used to clear filters but not to return a table. – Randy Minder Aug 28 '19 at 16:03 This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules. ... To Summarize: Filter Context. The combined table resulting from this filter only contains columns explicitly listed in SUMMARIZECOLUMNS as grouping columns or filter columns. expression – John Donnelly Nov 13 '16 at 17:33 And this feature is the basis for the dynamic behavior you're talking about. Client tools like Excel and Power BI almost always generate context transitions to evaluate measures in the reports. 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. The CALCULATE function is the most important one in DAX. In your edit I found your use of 'external filter' and 'internal filter' a little confusing. To summarize: A row context is not filtering the model in any way. In the case of row-level calculation, we use the row context. SUMMARIZECOLUMNS always combines all the filters on the same table into a single filter. Filter context filters, row context … 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"? If the table has many-to-one relationships with other tables, all the columns of the related tables are part of the filter, too. Example 1. Any DAX expression that returns a table of data. In The Definitive Guide to DAX I introduced such a function, but at the time of writing it was used only by Power BI and it wasn’t possible to include it in a measure, … In DAX there's no way to create a string dynamically and execute it (like in SQL, for example). You can combine filters using keywords like AND and OR and also nest one filter within another. I always thought that any filter context in place outside of DAX was considered an 'external' or 'outer' filter.
