SSRS select random records in tablix filter , possible
Question
I need to insert extra tab into existing report and display only @ratio percent of records randomly, so trying to solve this inside the tablix filter, is it possible, I don't think there is place for SQL in expression builder. I can include NewID() in original DataSet too like in case#1 below, but I prefer solve it without it, so it will be completely isolated change. This is just some methods I know in SQL for all reference. I also attaching test rdl for test. Tx all.M
SELECT TOP 40 PERCENT * FROM #TABLE ORDER BY NEWID() -- case #1
SELECT TOP 40 PERCENT * FROM #TABLE -- case #2
WHERE (ABS(CAST((BINARY_CHECKSUM (Report_Type+Name, NEWID())) as int)) % 100) < @rate
Tablix filter
Sorry, can not attach my rdl so pasating its xml right her, just plug your dsource, tx

I think this may be what you're after. You can calculate the percent within the query.
DECLARE @ratio AS DECIMAL
SET @ratio = 30 -- your percent parameter here
;WITH
test_data
AS
(
SELECT [row_count_nbr] = ROW_NUMBER() OVER(ORDER BY [Name]), tbl.* FROM (VALUES
( 'name1', 123)
, ( 'name2', 234)
, ( 'name3', 1234)
, ( 'name4', 56)
, ( 'name5', 4)
, ( 'name6', 34)
, ( 'name7', 784)
) tbl ([Name], [Value])
)
,
test_data_row_percent
AS
(
SELECT
[Name]
, [Value]
, [row_count_nbr]
, [percent_of_rows] = CAST(([row_count_nbr] * 100) AS DECIMAL) / CAST((SUM(1) OVER (PARTITION BY 1)) AS DECIMAL)
FROM
test_data
)
SELECT * FROM test_data_row_percent WHERE [percent_of_rows] <= @ratio
