Question : Filtering the SSRS report based on multivalue multiple parameters passed to stored procedure

I have four filter on a report BU, Reviewer Name, Approver Name, Approver status are four multivalue dropdown that should be present as report parameters in reporting services. i have 4 datasets that list all the values for the four columns and a stored procedure where the parameters are passed. the question is how can i design the stored procedure so i am able to filter the multivalue parameters independent of each other basically i need help with the stored prcoedure so i can pass in values as report parameters to this stored procedure and search independently, currenlty i can filter by business unit., other search condition based on Or does not seem to work what will be the approach for writing multi value input parameters sp in this case.

Answer : Filtering the SSRS report based on multivalue multiple parameters passed to stored procedure

You can use the test for null to ignore whatever parameter was not set, i.e. no filter on.

AND (@BU is null or ADP_FEED_0318.BU= @BU) --- BU. if it is null, it passes the check, otherwise must match filter
AND (@Approver is null or ADP_Feed_0318_2.FirstName + ' ' + ADP_Feed_0318_2.LastName = @Approver)
