Create a new calculated table using filtering based on a what-if parameter does not work

Anonymous , You can not use any slicer or what-if parameter value in the creation of a calculated table.

You can create a table using that as var in measure. Each measure that need this table, you need to have that

Measure =

var _Table_New = FILTER('Table', AND('Table'[Threshold Upper] >= 'Parameter'[Parameter Value],'Table'[Threshold Lower] <= 'Parameter'[Parameter Value]) )

return

countows(_Table_New )
