how to allow a null values in multi valued parameter - reporting-services

I have a requirement to include a null value in multi valued parameter. I'm using fetchXML code in my dataset. Please help me with it.
In my report I have 2 datasets in which first one is main dataset having parameter #P1.
For #P1 I have assigned Dataset2 as "Availible values" and "Default values".
Now, when I run the report I should get a dropdown with list of all values in dataset2.
So, here in that dropdown I was asked to add a null value also. Is it possible?
Note:Parameter will accept multiple values from user.

You can add a CRM filter parameter to your report, by adding a blank-value report parameter to your SSRS report.
The XML for the parameter would be like the following, considering you are working for example with the Account entity:
<ReportParameter Name="FilteredAccount">
<DataType>String</DataType>
<Nullable>true</Nullable>
<DefaultValue>
<Values>
<Value></Value>
</Values>
</DefaultValue>
<AllowBlank>true</AllowBlank>
<Prompt>FilteredAccount</Prompt>
<Hidden>true</Hidden>
</ReportParameter>
After you add this parameter, you will upload the report to CRM, and CRM will automatically create the parameter for you as SQL query (Value) and will load CRM filters. Any specific required filters could be saved to the report in CRM.
And note that this report parameter should be passed from SSRS to the stored procedure, which fetches the report filtered results.

Let's say you want to add a null option for selection to a list of codes from a query. All you need to do is add that to your result set by unioning it:
SELECT NULL AS Id, '<Null option>' AS Description
UNION ALL
SELECT Id, Description
FROM CodeTable
ORDER BY 1

SSRS Open sub report with provided parameters

I have a report which has 5 parameters and i want to open another report from this report which has 13 paramaters.
When i try to open this report it says some parameters are missing.
I want to know if it is possible like, if i do not pass parameters then it should ignore these parameters in repport and also in SQL query (all these are multivalue parameter).
I cannot use "allow null values" as these are multivalue parameter.
This is main report
These are parameters in sub report which i want to call
Can someone help me please? or i need to create seperate subreport with exact parameters everytime
There are two common ways of doing this.
Populate parameters with a list default values
In your subreport, taking #service as an example. If you can get a list of services from your database then create a dataset tat gives a list of distinct services, use this as the default value for your parameter. Then when you do not pass anything from the main report, the subreport will use all services.
Set the default parameter value to a fixed constant
The other option is to set the subreport parameters to a default value such as *all and then handle this when it is passed to your subreport's dataset query.
So the dataset query might be something like
SELECT *
FROM myTable
WHERE location in (#location)
AND (service = '*All' OR service IN(#Service)

Issues with Passing Multi-value Parameters to a Drill through Report

I have two reports were I pass multi-valued parameters to it's underlining data and both reports work very well independently. The parameter strings are being split using the function dbo.UTILfn_Split. When trying to drill from the main or Summary report into the sub or Detailed report all other parameters field in the report are populated except the multivalued parameter field. The parameter lists or value are listed in the detailed report but not selected and therefore cannot run the report even though the detailed report parameter property is set to allow multiple values. In both reports, the where clause is set "IN" not "=." How do I fix this?
In your Summary Report, when you pass the parameter to the sub or detailled report, the passed value parameter should be like this expression:
=join(parameters!yourMultivaluedParameter.Value,",")
after that, you pass the name of the parameter to the corresponding parameter in the dataset Detailled report.
In your SQL (SP), get the multivalues of the parameter by spliting it with your function
like following, depending of the result of your function, for exemple:
INNER JOIN dbo.SplitFunction( #yourMultivaluedParameter,',') tmp on tmp.yourColumn = ...etc...
Hope it helps...

ssrs - Forward pointing dependencies are not valid

In an existing SSRS 2008 r2, report, I am attempting to add a parameter called 'Customer_Category'. I am getting the following error message:
The report paramter 'CustomerNumber' has a DefaultValue or a ValidVaue that depends on the report parameter 'Customer_Category'. Forward pointing dependencies are not valid.
I am trying to determine how to fix this error. The 'CustomerNumber' is a parameter value that is obtained by reading from a dataset. In this dataset there are existing other parameters called 'Customer_Type' and 'Customer_Preference'. Both of these parameters obtain there values from selections that the user makes when the SSRS report is executing. There are no default values.
I am trying to have the 'Customer_Category' be the same way where there are no default values and the user must select the parameter value when the report is executing. There should only be one value that the user can select from.
The new parameter called 'Customer_Category' is the last parameter in the list of parameters. Does the order of parameters make a difference? If so, how can I move the 'Customer_Category' parameter in front of the customer_number parameter?
Here is the sql that is used from obtaining a list of customers from the dataset for customer_number:-
SELECT Distinct CustomerNumber
FROM BridgeUserCustomer
WHERE
Type = #Customer_Type
AND Preference = #Customer_Preference
AND Category = #Customer_Category
GROUP BY CustomerNumber
Would you tell me what is wrong and what I can do to solve the problem?
Summary
The order of parameters in your IDE (Report Designer or Report Builder) matters.
If you have a hierarchy of parameters (one level dependent on the other), the top-level parameter must appear first in the parameter list.
In SSRS these are referred to as cascading parameters.
Solution
Open the Report Data tab
Expand the Parameters folder
Select a parameter and use the up/down arrows to adjust order

How to pass multiple values to a multivalued parameter in SSRS

I will try to explain the issue as best as I can by oversimplifying the report structure. Report one contains 1 group called ResourceCenter and then one line of totals under it. The totals are actually a group but the grouping is done in SQL and are presented in a detail group. The report looks something like this:
Report 1
ResourceCenter 1
Total1 11
Total2 4
Total3 8
ResourceCenter2
Total1 12
Total2 11
Total3 6
From this report, I need to drill through to another report that has a bunch of multi-valued parameters. For the drillthrough, I am able to use single values for everything except for EmployeeNumber. For that, I need to be able to pass a list of EmployeeNumbers to the multi-valued parameter in Report 2. The EmployeeNumbers are not currently present in any DataSet or parameter in Report 1 but are based on ResourceCenter. So, if the user has run Report 1 and clicks on ResourceCenter 1, I need to be able to pass a list of EmployeeNumbers associated with ResourceCenter 1 to the multi-valued parameter in Report 2 in a way that Report 2 will handle it correctly.
NOTE: I should add that I have created two SQL functions that accept an input of ResourceCenter and then return a list of employees. One is a table-valued function that returns a single column of EmployeeNumbers. The other is a scalar-valued function that returns the EmployeeNumbers as comma-separated values. I then have some custom code that runs the SQL function in the background and returns the list. I have not had any success with returning a dataset that SSRS can use but I have been able to get the scalar-valued function to 'work' in the sense that I can create a field on a dummy report and see the output. I have not had any luck getting Report 2 to accept a comma-separated list, though.
This person was doing a drill-through and appears to have solved a similar problem with a multi-value parameter. In that case it had to be formatted for an IN clause.
=SPLIT(JOIN(Parameters!SomeParameterName.Value,","),",")
If Report2 won't take it in this format, you might have to add a separate single-valued parameter that will accept a comma-separated string, which you then have to parse.
I'm using SSRS 2016, and my datasets are based on stored procedures, but passing multi-value parameters to a drill down doesn't seem to be an issue anymore. By default, when you select a multi-value parameter it gives you something like Parameters!ParName(0).Value which would pass just the first value. But if you remove the (0) and just leave it as Parameters!ParName.Value, it seems to be passing all values fine.

Sending multiple values in ssrs parameter to subreport

Currently have three subreports, one main report.
Main report has two parameters - SELECTDATE and EMP_ID. Main report sends Order_Nbr to all subreports.
All subreports work perfectly when I only select 1 Employee and 1 date, but if I choose multiple values it blows up.
SQL has the column as an INT. I have both parameters in main report and subreport, SELECTDATE is set as Text with Multiple Values, and EMP_ID is set to Integer with Multiple Values. My queries has my date IN (#SELECTDATE) and emp_id IN (#EMP_ID).
It obviously sends the correct information to the subreports because it works, but I would like it to work with more values being passed. Love the current ability to check and uncheck employees and end of month dates, like it currently is set using the IN function in my query.
Make the Parameters on your sub report non-multivalue, remove any 'Available values' set.
Pass the multivalue parameter from you parent report as a string using the join method
=Join(Parameters!Emp_ID,",")
The EMP_ID parameter will be set to a comma delimited list, which is what a multivalue parameter sends to the query
I'm not sure how this works with text queries, but it works with stored procedures.
If the sub report is also used as a stand alone report you will need to add a new parameter to allow the user to send parameter values to #Emp_Id from a parameter the user can set
I guess you have not set the parameter in the sub report as Multi Select. If you have set the parameter in the sub report as multi select, then you could just send the parameter from the main report to the sub report as it is. See more at here
I used the following solution, which works in SSRS2016. This also works with text parameters.
Like suggested above, pass the parameter as a string to the subreport by JOINing the values.
Join(Parameters!EmpID, ",")
In your subreport, accept the parameter as text.
In the SQL of your subreport, use the string_split function of SQL 2016 to return a table of the values and simply join it to your main query. So basically if your parameter is named "EmpID_Multi" do
... JOIN (SELECT value FROM string_split ( #EmpID_Multi, ",")) mv ON mv.value= ...
Note: You might consider pulling the values into a temporary table for SQL optimization (sometimes the optimizer does funny things...).
