Update date-slicer in bookmark automatically

[sr97]

Hi all, 

Is there a way to update the date-slicer in a bookmark automatically to the most current date in a excel-file? When i say most current date, i mean the latest date in a excel-file ( and not today's date)

When I update my Power BI with new excel-files, I need to update the bookmark ( Remove filters are connected to a bookmark)  so i get the most current date.

Is there a way, so when i press "Remove filters", the slicer will be updated with the most current date from the new excel-file i attach to a sharepoint-folder?

Hi @sr97,

Thank you for reaching out to Microsoft Fabric Community Forum.

Power BI bookmarks cannot dynamically update slicer values — they store static slicer states. However, you can achieve your goal using a dynamic default value logic instead of relying on bookmarks. Here's how you can do it:
1) Create a dynamic "Latest Date" flag in Power BI: create a calculates column

IsLatestDate =
'dim_date'[Date] =
CALCULATE(
MAX('dim_date'[Date]),
ALL('dim_date')
)

• Use this logic in a slicer or visual filter:
• Add the date slicer as usual.
•  Use a page/filter slicer on IsLatestDate = TRUE.
• Remove the bookmark that holds the slicer state, and let this logic drive the default.

2)  Create a measure to capture the latest date

Latest Date =
CALCULATE(
MAX('dim_date'[Date]),
ALL('dim_date')
)

3) When your Excel file is updated and refreshed in Power BI, the MAX(Date) will always return the new latest date no manual action required.

Hi @sr97 ,

If the bookmark has the data turn on you cannnot do it since it saves the data at the point of the save of the bookmark.

For this I suggest that you use a Clear Slicer button on your report page, be aware if you have any other slicers those will also be cleared.

Hi sr97
To auto-update a Power BI bookmark's date slicer to the latest date in an Excel file from a SharePoint folder:

1. Connect to SharePoint:
   • Get Data > SharePoint Folder, filter to .xlsx, sort by Date modified (descending), keep top 1 file, load data.
2. Get Latest Date:
   • Create DAX measure: LatestDate = MAX('Table'[RecordDate]).
3. Set Up Slicer:
   • Add slicer for RecordDate, sort descending, single-select.
4. Update Bookmark:
   • Select latest date in slicer, update "Remove Filters" bookmark to capture slicer state.
   • Assign bookmark to button.
5. Automate Refresh:
   • Publish to Power BI Service, set up scheduled refresh with SharePoint credentials.

Test: Upload new Excel file, refresh dataset, click "Remove Filters"—slicer should show latest date.

Note: Slicers can’t dynamically default to measures. For dynamic control, consider a helper table with a "Latest" option (ask for details if needed).
