Handling multi-value parameters in VS 2005 / Crystal 2008

In my program I am trying to handle a multi-value parameter using the following code, passing it an array of type string with the values that the user selected, but using the following code returns a 'Missing parameter values' error.
    For Each crParameterFieldDefinition In crParameterFieldDefinitions
        If Not crParameterFieldDefinition.IsLinked And crParameterFieldDefinition.ReportName = "" Then
            crParameterValues = crParameterFieldDefinition.CurrentValues
            crParameterDiscreteValue = New ParameterDiscreteValue
            If crParameterFieldDefinition.EnableAllowMultipleValue Then
                Dim j As Integer
                Dim x() As String = Session("FieldDef")
                For j = 0 To x.GetUpperBound(0) - 1
                    crParameterDiscreteValue.Value = x(j)
                    crParameterFieldDefinition.CurrentValues.Add(crParameterDiscreteValue)
                Next
            End If
            Session.Remove("FieldDef")
            i = i + 1
        End If
    Next
I have also tried loading the values into a ParameterValues object and then using ParameterFieldDefinition.ApplyCurrentValues on it, which has been working fine for all of my single value inputs, but using that throws an error about a type mismatch. Any help at all would be appreciated.

There are a few samples to look at here:

Programmatically set Multi-value parameters

Hi, I hope someone can help.
I have a .net web application written in VS2008. I display reports within a report viewer object. I currently set report parameters within code using the SetParameterValue property within the report document object before passing the document to the viewer.
This works fine for single value parameters, but I have a report which accepts multi value parameters and I am having problems trying to find any information about if this can be done within my code. I understand the parameter is an array, therefore am I right in thinking I can pass an array into the SetParameterValue property?
Any help would be much appreciated.
Thanks

Hello Julie
You do not mention what version of CR you are using in .NET or what version of CR the reports were written in.
There is a fair number of good threads on this issue in the forum, see if searching comes up with anything.
Also, use the search box at the top right corner. That will search KBases, articles, Blogs, wikis, etc., etc.
Oh and sample apps are here:
https://wiki.sdn.sap.com/wiki/display/BOBJ/CrystalReportsfor.NETSDK+Samples
and the [Crystal Reports for Visual Studio 2005 Walkthroughs|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/2081b4d9-6864-2b10-f49d-918baefc7a23] is a great article to go through.

[Forum FAQ] How to configure a Data Driven Subscription which get multi-value parameters from one column of a database table?

Introduction
In SQL Server Reporting Services, we can define a mapping between the fields that are returned in the query to specific delivery options and to report parameters in a data-driven subscription.
For a report with a parameter (such as YEAR) that allow multiple values, when creating a data-driven subscription, how can we pass a record like below to show correct data (data for year 2012, 2013 and 2014).
EmailAddress                             Parameter
Comment
[email protected]              2012,2013,2014               NULL
In this article, I will demonstrate how to configure a Data Driven Subscription which get multi-value parameters from one column of a database table
Workaround
Generally, if we pass the “Parameter” column to report directly in the step 5 when creating data-driven subscription.
The value “2012,2013,2014” will be regarded as a single value, Reporting Services will use “2012,2013,2014” to filter data. However, there are no any records that YEAR filed equal to “2012,2013,2014”, and we will get an error when the subscription executed
on the log. (C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\LogFiles)
Microsoft.ReportingServices.Diagnostics.Utilities.InvalidReportParameterException: Default value or value provided for the report parameter 'Name' is not a valid value.
This means that there is no such a value on parameter’s available value list, this is an invalid parameter value. If we change the parameter records like below.
EmailAddress                        Parameter             Comment
[email protected]         2012                    NULL
[email protected]         2013                     NULL
[email protected]         2014                     NULL
In this case, Reporting Services will generate 3 reports for one data-driven subscription. Each report for only one year which cannot fit the requirement obviously.
Currently, there is no a solution to solve this issue. The workaround for it is that create two report, one is used for view report for end users, another one is used for create data-driven subscription.
On the report that used create data-driven subscription, uncheck “Allow multiple values” option for the parameter, do not specify and available values and default values for this parameter. Then change the Filter
From
Expression:[ParameterName]
Operator   :In
Value         :[@ParameterName]
To
Expression:[ParameterName]
Operator   :In
Value         :Split(Parameters!ParameterName.Value,",")
In this case, we can specify a value like "2012,2013,2014" from database to the data-driven subscription.

Multi-value parameters and strings with leading zeros

I have invoice number as a multi-value parameter. Invoice is a string,10 (VBRP.VBELN) .
Invoice number is my group. If I enter invoices 100 and 200 as parms, then I only get data for invoice #100 (the lowest value entered). But if I enter 100, 0000000100, 200, 0000000200 as parms, then I get data for both invoices. Is there a way to get around having to enter the invoice number in both formats. BTW, if I only enter 0000000100 and 0000000200 then I get no data.
Selection criteria is (VBRP.VBELN) = ?invoiceno --- parms are defined as allow muliple values and allow discrete values.

Oops, that's not gonna work with multi-value parameters. How about:
if IsNumeric((VBRP.VBELN)) then
ToText(Val((VBRP.VBELN)), "0") in {?invoiceno}
else
(VBRP.VBELN) in {?invoiceno}
end if
BTW, the reason why your original formula didn't work was because the "=" should have been "in". The above is needed only if the (VBRP.VBELN) field might contain leading zeroes.

How does IDP handle multi-value attributes in directory?

I have a directory referenced by the IDP where the mail attribute is multi-value. Assertions being received by the SP are indicating that the mail attribute is null or empty. How does the Oracle IDP handle multi-value attributes from a directory? Is there a way to select the first entry in an array of multi-values?

On the IdP side, passing of multi-valued attributes is supported. Read this section:
http://download.oracle.com/docs/cd/E10773_01/doc/oim.1014/b25355/configuring.htm#BCGCGFCJ
Snippet (under 'Delimited Data'):
"In addition to supporting and passing multi-valued attributes, Oracle Identity Federation can also support delimited data to provide multiple values for assertion attributes ......"
This information is also available on the OIF screen for 'Add Assertion Profile'.
On the SP side, mapping a multi-valued assertion attribute to a local user attribute is NOT supported. Read this section:
http://download.oracle.com/docs/cd/E10773_01/doc/oim.1014/b25355/configuring.htm#BCGGEAEA
Snippet (under Submit/Reset button):
"Note: Mapping an assertion attribute containing multiple values to a local user is not supported."
So, basically, there is no way to send only the first value of an LDAP attribute.

Setting multi-value parameters using ReportExecutionService

Does anyone know how to set multi-value parameters using ReportExecutionService in C#?
If I have
rsExec = new ReportExecutionService2005.ReportExecutionService();
ReportExecutionService2005.ParameterValue[] parameters = new ReportExecutionService2005.ParameterValue[2];
parameters[0] = new ReportExecutionService2005.ParameterValue();
parameters[0].Label = "Report_Begin_Date";
parameters[0].Name = "Report_Begin_Date";
parameters[0].Value = "4/15/2007";
parameters[1] = new ReportExecutionService2005.ParameterValue();
parameters[1].Label = "SalesID";
parameters[1].Name = "SalesID";
parameters[1].Value = ??? //Here, this parameter should accept multiple values like 200, 201, 202, etc.
rsExec.SetExecutionParameters(parameters, "en-us");
How would I set the SalesID to take multiple values?

Optional Multi-Value Parameters in a URL

I have 3 summary reports, that each need to hyperlink to 4 detail reports. The summary reports use multi-value string parameters that are set to "optional" (this is crystal 2008). I need to construct URLs to support these optional parameters. The opendoc documentation says to use "no_value" as the param argument, but that doesn't work - I get the string "no_value" in the selection criteria which causes it to fail. Ideally, I'd use either lsMMyParam="NULL" or lsMMyParam="", but neither works. Anyone ever done this?

hi Bob,
have you tried doing this...
&lsMPromptName=[]
lsM prompt / parameter values have to be passed with square brackets as far as i know.

How to handle multi valued attributes

Hi All,
I am supposed to populate multivalued attributes for a field in oim resource profile. Lets assume the field is mailbox. The issue is that I am supposed to reconcile this field from the directory server during initial load. The mailboxes are fetched from the DS based on organization. For provisioning I have to get the mailboxes from the database and these mailboxes are based on the role a user has. At the time of provisioing, I am supposed to populate the mailbox field with values the user already has been provisioned with and also display the mailboxes that he can get access to. I have created the mailbox as a resource with id and name as two of its fields. Could someone please tell me how do I handle this?
Thanks,
Supreetha

I am not sure if I could follow the same thing as mentioned in the link above. Here is my case, Role is a multi valued attribute which i need to handle in oim and is very different from the usual roles. For this purpose, I have created roles as a resource object with role_id as field in its process form.When an admin logs in to assign a new role_id, he should be able to see only those roles for assignment that the admin's org has. I have these org and role mappings in a custom table that I have created in the oim schema. How will I able to display only these available role_ids so that the admin can choose them and assign for the role resource.
Could you please let me know how do I do the config in oim?
Thanks,
supreetha

Handling Multi-Valued attribute in trusted reconciliation

Hi,
We have a requirement where an attribute is multi-valued in LDAP(Sun One Directory Server) which is a trusted source for OIM. We wanted to use oracle Out-of-the-Box connector for Sun Java System Directory Server. We wanted to bring in this multi-valued attribute into OIM, concatenate everything and populate it to a OIM User form attribute. Hence though the value is multi-valued in trusted source, we process it and populate as a single valued attribute in OIM. Since we run trusted reconciliation we are unable to bring this multivalued attribute for the user into OIM.
Can anybody suggest any other workaround available to achieve this functionality without touching connector source code?
Any help would be greatly appreciated.
Regards
Deepa

I would highly suggest writing your own custom code.
You'll need to create a UDF that is large enough to handle your concatenated value. A resource object marked as trusted object. A provisioning process defintion to map the value to the field.
Then write a custom scheduled task that will connect to the LDAP directory, perform your search using the modifytimestamp attribute to get all the values. Concatenate them together in your code and create the reconciliation event.
It will turn out to be smoother than dealing with an entity adapter that runs everytime an event occurs which might not be related to this item.

How to include NULL in multi value parameters

Good Morning,
I'm posting this question after i tried other links and was not successful. I'm using a report builder to create a report. SSRS2008R2.
I have a sql to get the data into the data set. Source is ORACLE DB. The query is pulling lastname,firstname,dob,joindt,divname. I created a parameter in the SQL :
WHERE DIVNAME IN (:divname).
I created another dataset (select distinct divname from table2) and selected the paramter properties to get the values from the second dataset and selected it to be multivalued. However the user wants to see the NULL's or BLANKS that are in the DIVNAME.
Can some one please tell me as how i can acheive this?
When i run the query in the sql plus i get (null) values as well, but when in the second dataset i run the query i just get the DISTINCT divnames and a "BLANK" field (in SSRS)
Thanks

Hi thinkingeye,
According to your description, you want to include the null values in your multiple values parameter. Right?
In Reporting Services, we can't allow both null values and multiple values in a parameter. In this scenario, since you have created a dataset for getting distinct divname, we suggest you try "select distinct isnull(divname,-1) from [table]" in this
dataset so that all the null values will return -1. Also using isnull() function to replace divname in other query. This might be the most effective work around.
Reference:
Null and Multi-value parameter possible
Include Null Value Multi-Value Parameter list
If you have any question, please feel free to ask.

Multi-Value Parameters to Oracle Stored Procedures via SQL Commands

Hi,
When you used stored procedure in CR, you need to declare REF CURSOR, This type of cursor is a dynamic cursor not a static cursor. Hence, you are able to manipulate dataset in this type of cursor.
Regards,
Titanium0203

As far as I know the documentation on CR & stored procedures says that the REF CURSOR has to be a strongly bound one.
Could you go into a little more detail? Do you mean I should put a multi-valued parameter into a REF CURSOR? Can you post some code snippets here?

How to pass multi-value parameters to DDS (data driven subscription)?

Using RS2005, how should multivalue parameters be stored in a database field so that a data driven subscription can properly read and use them? I have so far had no luck using syntax of:
1) parm1, parm2
2) parm1,parm2
Do single qutoes need to explicitly wrap the values? Can you please provide an example and a SQL INSERT statement using parm1 and parm2 to demonstrate what to store in the database field?
Thanks!!

I have skimmed through this an have ran into this problem before but not with RS specifically, but with other ASP.NET apps I have built. Maybe this work around will help.
In my database I created a table function I call udf_Split List. It looks like this: (Can't remember where I got this from, but it's not my own.)
CREATE
FUNCTION [dbo].[udf_SplitList]
@List
varchar(max),
@SplitOn
nvarchar(5)
RETURNS
@RtnValue table
Id
int
identity(1,1),
Value
nvarchar(100)
AS
BEGIN
While
(Charindex(@SplitOn,
@List)
> 0)
Begin
Insert
Into @RtnValue
(value)
Select Value
=
ltrim(rtrim(Substring(@List,
1,
Charindex(@SplitOn,
@List)
- 1)))
Set @List
=
Substring(@List,Charindex(@SplitOn,
@List)
+
len(@SplitOn),
len(@List))
End
Insert
Into @RtnValue
(Value)
Select Value
=
ltrim(rtrim(@List))
Return
END
Then, in my query I used the following parameter: QueriedField IN(select value from dbo.udf_SplitList(@Parameter,',') (I used commas to separate the list, but you can use whatever you like (;,|,*, etc.)
For you @Parameter would be your DDS list parameter. Hope this helps. You can enter your list like Item1,Item2,Item3 etc.

Multi Value Parameters help

Hi Gurus
In the main dataset query i created a parameter "where k.jlocat=:LOC or :LOC is null". These are ORACLE Parameters and hence the :. In another dataset i created a simple query as
select distinct jlocat as LOC
FROM TABLE1
Every thing works fine so far. Now i want to select multiple values for this i edited the @LOC parameter to select multiple values and changed my WHERE CLAUSE in the main dataset as where k.jlocat=:LOC or :LOC='All'.
Now when i save and run the report , i cannot click on 'Select All' as it gives me an error:ORA-00907: missing right parenthesis.
I'm confused as where i'm missing the right parenthesis.Please need advice.
Thanks

Hi Pmunshi,
The error "ORA-00907: missing right parenthesis." occur when you entered a left parenthesis, but missed the closing right parenthesis; or you entered invalid data within the parentheses. Please refer to the link below to see the detail information.
http://www.techonthenet.com/oracle/errors/ora00907.php
In a Reporting Services report, if we check the "Allow Multiple values" option, than we need to change the "=" operation to "In" in the query.
where k.jlocat in(:LOC)
Besides, which features do you want to achieve by using " or :LOC="All" "? If we check the "Allow Multiple values" option, we do not add any extra query. If we select "Select All" option for this parameter, it will return all the records.
If I have anything misunderstood, please point it out.

How to Handle Multi Value Indexes

Hi all,
i'm a newbye and i've a class attribute which is a String Array, and i want to create a secondary index on this attibute.
I'm wondering which is the best solution to achieve this.

For new users we recommend the DPL. It was created for ease of use.
However, the DPL doesn't support arrays as key fields. So you would have to concatenate the strings with a delimiter and use a single String field, or if the number of strings is fixed use a composite key with a separate String field for each element. Some references are:
http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/persist/model/SecondaryKey.html
http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/persist/model/KeyField.html
If you use the Base API or the Collections API you can use a tuple binding to create a secondary key DatabaseEntry from a String array. For example, you can call TupleOutput.writeString for each element.
http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/bind/tuple/TupleBinding.html
What sort order for your key are you expecting? I assume you want the keys sorted by each string in array element order. That means you should NOT write the length of the array at the beginning of the key, since that will cause the sort order to be primarily based on the array length. Instead you can write an empty string as a terminator, or use TupleInput.available to test for whether you've read all strings in the key. The latter is recommended.
I assumed above that the array length is variable. If it is fixed length, you don't need a terminator.
If you don't care about key sort order, consider using a hash of the String array as the key. The hash field could be a single key field, which would work with the DPL.
I'm giving you a lot of general info. If you can be more specific about what you're doing, I can give more specific advice. I suggest that you start with one of the APIs and try doing what you want. Then you can post specifics about the questions you run into.
