Hi Lavandula,
According to your description, you want to calculate the numbers of the record of a measure for a specific day, right? In this case, you can use
Count function which returns the number of cells in a set to achieve you requirement. Here is a sample query on Adventure Works for your reference.
WITH
MEMBER [Measures].[SetCount] AS
COUNT([Product].[Product].[Product].Members)
SELECT
{[Measures].[SetCount]} ON COLUMNS
FROM
[Adventure Works]
Besides, if you want to count the cell numbers with a condition, you can use
Filter funtion inside the Count function.
WITH MEMBER [Measures].[High Volume Products Count] AS
Count(Filter([Product].[Product].[Product], [Measures].[Internet Order Quantity] > 5))
SELECT [Customer].[Customer Geography].[Country] ON 0
, [Date].[Calendar].[Date].MEMBERS ON 1
FROM [Adventure Works]
WHERE [Measures].[High Volume Products Count]
