I know that I can create a slicer from a column on my dataset table so that I can filter my table data. And that I can use the visual interaction option within the same report.
But what I need is to have a dashboard where I have slicers that can filter all or some of my visuals from different reports.
Is there a way I can do that?
Also can I create slicers from different datasources (or dataset tables) so that I have for example a "Years" or "Departments" table I can use everytime I have dasources that have these columns.
Slicers are designed to be used in Power BI reports, NOT in dashboards. The only way I know for slicers to work across different data sources is if a relationship(s) is(are) established between the data sources.
Hope this helps, thanks.
At this point in time, it doesn't look like relationships can be established on the Power BI service.
As a general rule of thumb, if you want to get the most out of Power BI, it's best to do all the heavy lifting in Power BI Desktop.
Power BI Service is more suitable for accessing cloud/online data sources like Google Analytics and the like.
