SSRS Multi-Value Parameter Error

Question

Goal: I have an SSRS report that uses a hidden parameter to capture the UserID, a multi-value drop-down parameter that displays Branches, and another multi-value parameter that will show Sales Reps related to those Branches. The idea is that the user can only view Branches and Sales Reps where their UserID is equal to the name of the Branch.

Problem: If the user is given access to view the branches Chicago and New York, and selects only those Branches, the report runs fine. Data is displayed for only those two Branches.

If the user selects only Chicago an error message is displayed.

If the user Selects only New York an error message is displayed.

If the user chooses 'SELECT ALL' the report displays data for all Branches (even Branches they should not have access to).

ERROR MESSAGE: Conversion failed when converting the nvarchar value 'Chicago' to data type int.

I'm using a query in the Dataset, not a stored procedure. Should I be using a stored procedure instead?

I'm using an 'IN' operator in the WHERE CLAUSE:

WHERE ReportIDTable.ReportID = 1 
AND ReportIDTable.UserID = @UserID
AND ((Branch IN (@BranchID)) OR Branch = 9999)

I've tried using JOIN() and SPLIT() functions and I don't see a difference.

I've done a lot of research and I can't seem to get the issue solved. Any help would be much appreciated!

The @BranchID parameter is set to TEXT already and is actually populated by another query.

SELECT 'ZZ <Untracked Sales>' AS ParentID
UNION
SELECT ParentID
FROM     ReportDistribution WITH (NOLOCK)
WHERE  (ReportID = 1) AND (ReportHierarchyID = 3)
GROUP BY ParentID

Answer 1

I am assuming the BranchID is and int and its name a string and therefore you branches dataset looks something like this.

BranchID BranchName
1        Chicago
2        New York

In your parameter, make sure your Value is pointing to the 'BranchID' column and `Label' is pointing the 'BranchName' column.

Once you have checked this, set your parameter value to be text (I know it's a number but try it....)

You don't need to use a stored proc, join or split, what you have should be fine.

If you still have problems, post the dataset query for both the main query and the parameter plus some sample output from each if possible.
