Hello, None of our masterItem appears in the selections (check mark: display fields not checked) We have used the workaround indicated in your posts so that materItems are properly displayed in active selections. In any case, it would seem that as soon as you save through the expression editor it adds an '=' and then the dimension is no longer displayed. You will understand well that an application based on MaretItems not allowing to filter on it questions me. The first feedback on this problem dates back to 2014, I guess since then you have done the necessary to correct this Bug.
