Or from another perspective, if I merge the above table with a fact table how can I only merge the only the latest patch base on the year? In your case, you Create a new measure to calculate the date difference between the date slicer value and the date field in your table as below: elapsed duration based on slicer = DATEDIFF (FIRSTDATE ( 'Tasks' [Start]), 'Calendar' [Slicer Selection],DAY) CFA Institute Does Not Endorse, Promote, Or Warrant The Accuracy Or Quality Of WallStreetMojo. Female students = CALCULATE ( [Subject count],Students [Gender] = "F") We have provided [Subject count] measure as an expression to calculate function and Student gender = "F" as a filter. Internally, SELECTEDVALUE is just syntax sugar generating the following corresponding syntaxes: You should use SELECTEDVALUE in all those cases when you need to read a single value selected in the filter context, obtaining blank or another default value in all other cases. Since what we would like to happen is [City] + , + [PostalCode], the syntax should be: After pressing enter, Power BI will populate your new column with the desired values: If the values appeared on your end, congratulations! Youll see all the columns that belong to that table. This function is the key in creating the solution for this example. Heres why, MSP best practices: PC deployment checklist, MSP best practices: Network switch and router maintenance checklist.
