Time slicer navigator
SSRS Mobile reports: Time slicer navigator automatically accept only "day"-level (date type) value.
Working with SSAS as source - gives additional complexity in dataset design, with no option to utilize time dimension already available in SSAS cube.
Not all reports are on "date" level. If you need to have only "last few years" report, to be able use time navigator: still need "Date"-level value in dataset.
Add option in time navigator: 1) to choose which field must be used from dataset for time navigator. 2) allow upper time levels to choose as lowest level (not date-type value, but for yyyy-MM or yyyy-QQ, for example).
