The user interface of Power BI does not feature a specific tool to specify a target for the filters defined at the page and report levels. Using as filter the columns used for the relationships guarantees that whatever the column used for filtering this would be mapped over the relationship. In my visual, I want to ignore this filter for just this one measure. 05-12-2021 10:59 AM. The DAX expressions aggregating data over a parent-child hierarchy must consider the sign used to aggregate data at lower level of a hierarchy node. Here's a good write up of why USERRELATIONSHIP won't work in this sceanrio: linky* The LOOKUPVALUE below works as well: =LOOKUPVALUE( People[FullName] ,People[PersonID]. 0. Because the relationship is now invalid, DAX creates a blank row which is immediately visible in the report. Alternatively, when the user selects Unit Price, we use the formula with Unit Price. The ALLNOBLANKROW function only filters the blank row that a parent table, in a relationship, will show when there are one or more rows in the child table that have non-matching values to the parent column.
