TL;DR. I would like to be able to get the SELECTEDVALUE of a field parameter the same as a normal slicer which I think is a very simple request. And as a second request that might violate the spirit of PowerBI, I'd like to get the output of a field parameter. If not always, at least when its a categorical dimension. Now on to my more detailed rant 🙂
I have been using field parameters and I think there is a very simple feature missing. There should be an additional component that returns the chosen label. I am unable to create a dynamic title because the only thing that returns a usable string is the Field Parameters argument which includes an uncleaned table name. I ran into an issue yesterday trying to dynamically switch a measure accompanying the field parameter output, a measure recreating the GT of column feature. Today I have run into the same issue trying to use dynamic titles the way they can normally be used. I can use an additional measure that uses the field parameters and then outputs a chosen cleaner string but it seems to me that this is a simple feature to add. Should I make a feature request? I don't know the utility of such an action.
Additionally it would be nice to have an additional component that would allow the values of the field parameter to be usable in a slicer. For example, If I want to use a field parameter to combine Year, Quarter, and Month columns so I can switch the date axis between those (especially if I am using a custom time grouping), I can do so. But I have no way to then have a second single slicer that will show the Years if Year is selected, so I can filter for a given year. On various projects I have spent a disappointing amount of time creating a way to switch between date levels and I thought field parameters were the solution but they are only half of what I need. Basically I want slicer 1 to say Year, Quarter, Month. And I want Slicer 2 to say 2020, 2021, 2022 if I select Year, Q1 2020...Q4 2022, if I select Quarter, and 2020 January... 2022 December if I select Month. I always have to create my own columns because of the way PowerBI always sorts Q1 before Q2 no matter which year it is, same with months. I recall that there is a way to drill down that shoudl work but then again half the projects I have worked on have had custom ways of grouping into weeks/months/quarters/years so even then I still would need field parameters to do what I want to work right. But now I am rambling.
