I have different companies each with its own dataset. Can I create a single analysis/dashboard and have a filter, filtering the analysis with the different company datasets
Hello Sylvester: Do you have a field/column in each dataset to represent a company? If not, suggest you add a column to identify the data for different company in each dataset.
More info on dataset join: Joining data - Amazon QuickSight, once data is joined, in analysis you can use the added company field for filtering.
