Using Calculate function with two tables

Hi  SS0101 ,

You can try the following measure:

Measure =
var _select=SELECTEDVALUE('Calendar Table'[Date])
return
COUNTX(
    FILTER(ALL('projects table'),
    _select>='projects table'[StartDate]&&_select<='projects table'[EndDate]),[project])

Or add an ALL() function to the original Dax.

ALL function (DAX) - DAX | Microsoft Learn

If it doesn't meet your desired outcome, can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data. We can better understand the problem and help you.

Best Regards,

Liu Yang
