Custom Tooltip - How to Implement

Hi maazbinsalman99 

You can make one universal tooltip for all KPI cards so that there is no need for 60 pages.

Create the 'KPI Meta' table.
* Create one Tooltip Page. On this page, place three card visuals with these simple measures:
* Title A = SELECTEDVALUE('KPI Meta'[Title A])
* Title B = SELECTEDVALUE('KPI Meta'[Title B])
* Title C = SELECTEDVALUE('KPI Meta'[Title C])
* Configure Each KPI Card (The 60+ cards):
* For each card on your main report page (e.g., the "Revenue" card):
* Go to the Filters pane.
* Add a visual-level filter by dragging the 'KPI Meta'[KPI] column to the "Filters on this visual" well.
* Set the filter type to "Basic filtering" and select the one KPI that matches that card (e.g., select "Revenue").
* Go to the card's Format settings Tooltips and set the Page to your new tooltip page.
Now, when a user hovers over the "Revenue" card, the visual-level filter ('KPI Meta'[KPI] = "Revenue") is automatically passed to the tooltip page, which then correctly displays the definitions for Revenue.

Best regards,
