This article describes the differences between HASONEVALUE and ISINSCOPE, which are two useful DAX functions to control the filters and the grouping that are active in a report. Specifies cross filtering direction to be used in the evaluation of a DAX expression. It comes in handy when you need to change or ignore Power BI model relationships while evaluating a calculation.

However, writing a DAX expression that can have these two options both in one query can be a bit of challenge. The FILTER Function for the current example will use the following syntax:. The argument specifies a column reference, and the function follows a chain of one or more many-to-one relationships to fetch the value from the specified column in the related table. Here is a role defined in a user table with DAX filter below; [email]=UserPrincipalName () This DAX filter on the User table would filter the User Profile, but it won’t filter the Profile table, so as a result, it won’t filter the transaction table.

This article describes the behavior of auto-exist in DAX, explaining the side effects of combining slicers on columns of the same table in Power BI. If the two variables return the very same number, then DAX is working in a filter context at the month granularity level or above that (such as the year). This article explains how to use KEEPFILTERS to intersect instead of overriding an existing filter context in DAX, simplifying the code and improving performance.
