Missing Parameter in class method

Hi,
This is with regard to the Survey transaction. For survey, I did some modifications and I did the modifications based on a parameter in class method CL_UWS_PUBLISHING=>PUBLISH. It was working fine in our development server. But when I ported it to the Quality system, an erro appears telling that the parameter ID_SURVEY_ID is not available in the system.
As part of the implementation, our team has applied several notes to the application. Is it that, this parameter came as part of some note? If so, how can I find the relevant note. I searched for notes regarding survey but didn't find this one.
Please do help me in this regard.

Field symbol as import parameter in class method ???

Hi everyone,
is it possible to pass a field symbol as an import parameter to a method in a class? If yes, how do I define the data type of the import parameter? I'm trying to work with field symbols as the program doesn't know what kind of structure the program parameter p_srcdso has. Coding example would be something like this:
PARAMETERS: p_srcdso TYPE rsdodsobject DEFAULT '/BIC/AKVI0001'.
DATA: lr_srcpkg TYPE REF TO data.
FIELD-SYMBOLS: <fs_table> TYPE ANY TABLE.
CREATE DATA lr_srcpkg TYPE TABLE OF (p_srcdso).
ASSIGN lr_srcpkg->* TO <fs_table>.
SELECT *
FROM (p_srcdso)
INTO TABLE <fs_table>.
CALL METHOD cl_ref->create_somethign
EXPORTING
i_source_package = <fs_table>.
Thanks,
Alex

Halo Alexander,
You can use TYPE REF TO DATA( say the parameter name is i_data) as the importing parameter of the method create_somethign and inside the method you need to dereference it using data reference variable again.
data: dref type ref to data.
field-symbols: <fs_table> type table.
create data dref like i_data.
assign dref->* to <fs_table>.

How to pass entire class as a parameter in a method of other class- OpenScr

Hi Folks,
Whenever we create a script in OpenScript, it can contain only one class. However I want to declare several variables in a class/script and pass this entire class B as a parameter in a methodA of classA.
What I mean by mean that is , I create ClassB something like below
public class MyParams.....
variable1;
variable2;
variable3;
variable4;
variable5;
public class Original.....
public void methodA(MyParams params)
params = new MyParams();
field1 = params.variable1;
field2 = params.variable2;
field3 = params.variable3;
field5= params.variable5;

Hi
I have a stand alone program (can be used by all other users) which will accept request_id and To_Email as parameters. I am developing a new request set in which I want to incldue this stand alone program and want to pass Prog#1 request Id to the 2nd stand alone program as a parameter so that I can send the output of the Prog#1 to the users through E-mail.
Do we have any options to pass Prog#1 requeset id in to Prog#2 as a parameter in the request set without modifying the stand alone concurrent program code.
Please note that i dont want to change stand alone program code becuase this code/program was developed to work in general for all the users and I dont want to change this code for new requirement/purpose...
Hope you understood my requirement...
Thanks!!

How to pass importing parameter of super class method to subclass method?

hi all,
i have defined a class
CLASS CUST_REPORT DEFINITION.
PUBLIC SECTION.
    METHODS:DATA_RETRIVE IMPORTING CUSTID_LOW TYPE ZCUSTOMER-ZCUSTID
                                   CUSTID_HIGH TYPE ZCUSTOMER-ZCUSTID.
    DATA:IT_CUST TYPE TABLE OF ZCUSTOMER,
         WA_CUST TYPE ZCUSTOMER.
ENDCLASS.                    "cust_report DEFINITION
The method DATA_RETRIVE   in this class has two importing parameters named CUSTID_LOW   and CUSTID_HIGH.
then i have defined subclas of this clas.
LASS CUST_ORD DEFINITION INHERITING FROM CUST_REPORT.
PUBLIC SECTION.
    DATA:IT_ORD TYPE TABLE OF ZORDER.
    METHODS:DATA_RETRIVE REDEFINITION,
           DISPLAY.
ENDCLASS.                    "cust_ord DEFINITION
Method DATA_RETRIVE   is redefined.
So how to pass importing parameteres of super class method to sub class method with the same name.
Thanks and Regards,
Arpita

Hi,
I tried like this.
METHOD DATA_RETRIVE.
CALL METHOD SUPER->DATA_RETRIVE
      EXPORTING
        CUSTID_LOW = I_CUSTLOW
        CUSTID_HIGH = I_CUSTHIGH.
ENDMETHOD.
But parameters I_CUSTLOW and I_CUSTHIGH are not getting values after call to method.
Thanks and Regards,
Arpita

Error creating vendor w/ JCo FM VENDOR_INSERT- Missing parameter w/ PERFORM

Dear all,
I have followed the following thread and found it very useful as we need to create vendors from an external system in R/3 using the JCo as well. We are doing all the steps specified in previous posts and calling FM VENDOR_INSERT but when I execute the function it returns an exception:
JCoException: (104) RFC_ERROR_SYSTEM_FAILURE: Missing parameter with PERFORM.
We have checked and all the needed BAPIs are enabled but we are stuck at this first step. I have tried a variety of things but nothing seems to work. Not sure how I can specify the PERFORM parameter using JCo. Did anyone else fase this issue?
Here is what some of the relevant Java code looks like:
        JCoFunctionTemplate tmplt1 = repository.getFunctionTemplate("VENDOR_INSERT");
        JCoFunction vfunc = tmplt1.getFunction();
        JCoParameterList vparams = vfunc.getImportParameterList();
        JCoStructure jcs= vparams.getStructure("I_LFA1");
        try
             LocalSupplier s = getSupplier1();
             jcs.setValue("MANDT", "010");
             jcs.setValue("NAME1", s.getSupName());
             jcs.setValue("NAME2", s.getSupName2());
             jcs.setValue("PSTLZ", s.getSupPostalCode());
             jcs.setValue("ORT01", s.getSupCity());
             jcs.setValue("LAND1", s.getIdCountry().getIsocode());
             jcs.setValue("STRAS", s.getAddress1() +", " + s.getAddress2());
             jcs.setValue("MCOD1", "test");
             jcs.setValue("KTOKK", "ZKRE");
             jcs.setValue("SPRAS", s.getIdmasterSupplier().getIdlanguage().getLocale());
             jcs.setValue("STCD1", s.getIdmasterSupplier().getTaxId());
             jcs.setValue("TELF1", s.getTelephone());
             jcs.setValue("TELFX", s.getFax());
             execute(vfunc, destination);
        catch(Exception e)
            System.out.println(e.toString());
            e.printStackTrace();
            return;
      * Method execute will call a function. The Caller of this function has
      * already set all required parameters of the function
     public static void execute(JCoFunction function, JCoDestination dest) {
          try {
               JCoContext.begin(dest);
               function.execute(dest);
               JCoContext.end(dest);
          } catch (JCoException e) {
               e.printStackTrace();
Any help from some of view that have succesfully implemented vendor creation using the JCo would be highly appreciated.

Hi,
as I just wrote in the previous thread,
don't use function module VENDOR_INSERT.
As written before it is an update task FM. And also it do not check any field validity.
This is the best way to face inconsistencies in the future.
As you have also noticed, troubles and difficulties will come very soon related to the address management.
In standard there is NO FM or BAPI to do so.
The only supported option is via batch-input or idocs. Eventually, LSMW could help
See [note 384462|https://service.sap.com/sap/support/notes/384462]
With ECC 2005, a synchronisation class can help a lot. See class VMD_EI_API.
With ECC 2005 ehp3, you have an eSOA service to create vendor asynchronously. Not all fields are supported.
In other words, just create a BAPI to transfert your own parameters then either make a batchinput which will call XK01/XK02 in batch, either trigger class VMD_EI_API

Calling the super class method from the subclass

Hi all,
I have a question about inheritence and redefinition of methods. Is it possible to call the superclass implementation of a method which is redefined in the subclass in another method of the subclass?There are possbilities like creation of an explicit super class instance or delegating the super class method implementation to another method which is also protected etc. What i mean is, is there a direct way of calling it?We have ,me, as the reference for the instance we have(which is the subclass instance in this case), is there also a way of pointing the superclass implementation(with super we can reference in the subclass redefinition, my question is if we have such a parameter in other methods of the subclass too)
Thanks in advance
Sukru

Hi,
The super reference can only be used in redefined methods to call superclass implementation . So probably what you can do is use upcasting and access the required superclass implementation. I can think of only this way...;-)
Ex data lr_super type ref to cl_superclass
lr_super = lr_subclass.
lr_super->method().

Why do I get Missing Parameter Values error from CrystalReportViewer in VS2005

Post Author: eseidel
CA Forum: .NET
Hi everyone,
I have spent way to much time trying to figure this problem out and am getting no where now. I was hoping someone with more experience in CR for VS2005(I think v.9) and VS2005 may be able to help. I have a report with 10 parameters that Im setting in code. I have another 3 parameters in a subreport(with same names as 3 in main report) that are being pushed in(I hope) through my ApplyParams() method. I have checked the output of each parameter before and after it is assigned in ApplyParams. All values are being set....So why do I keep getting an error when I run it for Missing Parameter Values no matter what I do? The error comes after SetDBLogonForReport(myConnectionInfo). I have been struggling with this problem for almost 3 days now and have tried numerous approaches. If I remove the subreport it works ok. Why is subreport not getting parameters(I think this is where the problem stems from)? Please any advice would be greatly appreciated. Thank you. If need be I can e-mail the report but I don't know how much that will help without being able to access the datasources.

By any chance are the parameters in your subreport stored procedure parameters?
There was a specific fix for stored procedure parameters available from:ftp://ftp1.businessobjects.com/outgoing/CHF/crnet20win32x86_en_chf.zip
The specific fix is described in the readme under Problem ID # ADAPT00532856

CrystalReportViewer: "Missing parameter values with implemented error event

I'm using the CrystalReportViewer in APS.net (C#), and try to display a report in it.
I've implemented the error event of the viewer to show the user a different error message than the viewer itself does.
         this.CrystalReportViewer.Error += new CrystalDecisions.Web.ErrorEventHandler(CrystalReportViewer_Error);
      protected void CrystalReportViewer_Error(object source, CrystalDecisions.Web.ErrorEventArgs e)
         var msg = "Error in CrystalReportViewer\r\n{0}".FormatInvariant(e.ErrorMessage);
         throw new InvalidOperationException(msg);
But.... Now if I want to show a report that has parameters in it, the parameter page does not appear before the report itself. How can I make my code work (without removing the implementation of the error event), so the viewer first shows the parameter page, before showing the actual report?

And in the Page_Load method:
this.CrystalReportViewer.Error += new CrystalDecisions.Web.ErrorEventHandler(CrystalReportViewer_Error);
I've done this so i can show my own error page to the user of the website. Otherwise the CRViewer shows his own error, and I do not want the user of the website to see this 'technical' error.
So i've implemented the CrystalReportViewer.Error method:
protected void CrystalReportViewer_Error(object source, CrystalDecisions.Web.ErrorEventArgs e)
   // Missing parameter values.
   var discardToShowParameterPrompt = (e.ErrorMessage.ToUpperInvariant() == "Missing parameter values.".ToUpperInvariant())
     || (e.ErrorMessage.ToUpperInvariant() == "Ontbrekende parameterwaarden.".ToUpperInvariant());
   if (discardToShowParameterPrompt)
      _Log.Debug("The parameter screen should be displayed now.");
   else
      var msg = "Error in CrystalReportViewer: {0}".FormatInvariant(e.ErrorMessage);
      throw new InvalidOperationException(msg);
If I load a report with no params in the report, the page shows immediately the report.
If I load a report with params in the report, the params page is shown, the user can enter the param values, and after pressing OK, the report is shown.
If an error occurs (for example the report cannot connect to the database), the viewer does NOT show the error (because i've implemented the _error event) but my code throws an InvalidOperationException, and this is handled by code so the error is logged to a file, and the user gets a user friendly message on the website.
If i do not implement the _error event, the user will see the technical error in the crystal reports viewer.
If I comment out the code where I'm looking for the string "Missing parameter values." (or "Ontbrekende parameterwaarden") the parameter page will not be shown, and an error will be thrown by the Crystal Reports viewer.
If I put e.handled = true in the _error event, and there is an error (for example the database cannot be found), no error will be thrown, and there is nothing to see in the viewer.
So for now the only way to get the params page is to implement the _error event the way i've done in the above code, checking the error message on a string value.

Error Missing Parameter Values

I am very inexperinced in VB and ASP.Net.
That being said I have used forums and tutorials to develop the code below.
In the code I have hard coded some values to be passed to the report for testing...see num_inv and ser_inv.
When I run the code I get an error "Missing Parameter Values".
If I remove the lines that setparamervalues and turn on the enableparamaterpromt the report works fine and I can manually enter the values and see my completed report.
More Details...
The Crystal Report uses an ODBC connection to a SQL Server. I am only using one view to feed the report and there are no subreports. I am buidling the web app in VS2010 with the crystal reports version for VS2010 installed.
Dorry if I didn't give enough information...I don't know what else is relavant.
Any help would be greatly appreciated!
    Private Const PARAMETER_FIELD_NAME_1 As String = "Invoice"
    Private Const PARAMETER_FIELD_NAME_2 As String = "Serial"
    Private Sub WebForm2_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
        ConfigureCrystalReports()
    End Sub
    Private InvoiceReport As ReportDocument
Private Sub ConfigureCrystalReports()
        Dim num_inv As Integer
        Dim num_ser As Integer
        num_inv = 880822
        'Request.QueryString("inv")
        num_ser = 1
        'Request.QueryString("ser")
        InvoiceReport = New ReportDocument()
        Dim reportPath As String = Server.MapPath("S36 Invoice.rpt")
        InvoiceReport.Load(reportPath)
        InvoiceReport.SetParameterValue(PARAMETER_FIELD_NAME_1, num_inv)
        InvoiceReport.SetParameterValue(PARAMETER_FIELD_NAME_2, num_ser)
        CrystalReportViewer1.ReportSource = reportPath
    End Sub

I would start by enabling the parameter prompt and passing the parameters in code. You will only be prompted for the parameters that did not receive an acceptable value. This will let you see if your code to set the values is working for one or neither of your parameters. Calling the setparametervalues method will not return an error if the value isn't accepted.
Also, make sure your datatype is the same as defined in the report, and make sure you have no differences in the parameter names. Note, if the parameters are automatically created in the report because they came from a stored procedure, you need to include the @ symbol in the name as you see in the designer.

ReportDocument.Export() raises "Missing Parameter Values" exception

Hi
Recently I encountered a question about SAP Crystal Report that I have a rpt file with several sub reports and I am required to make the data source to be XML with http/https URLs. I created different .NET pages which returns XML stream as data source for both main report and sub reports in my rpt file, and also created a sub report links which pass dynamic parameters from main report to the sub reports, everything worked fine when I entered the necessary parameters only for the main report in the design tool, both the main report and sub reports displayed perfectly.
But it did not work in my .NET application which export the reports to PDFs, I referenced “CrystalDecisions.CrystalReports.Engine” and some other necessary DLLs into my project, and then I created an instance of ReportDocument, loaded the rpt file, set parameters which used in the main report, set connection info, and at last when I export the report it throw out an exception with “Missing Parameter Values” error message, even though I removed the sub report links which pass parameters from main report, the exception still occurred, but when I removed all the sub reports, and only export the main report it worked!!
Here is a result of my attempts:
Main Report
Sub Report
Result
1
With XML data source
No report
Works fine with dynamic parameters set to the http/https url which returns an xml results
2
With XML data source
Pass a static value and print it on the report
Works fine.
3
With XML data source
Create a SQL command WITHOUT any parameters passed from main report
Works fine
4
With XML data source
Create a SQL command WITH a dynamic parameter passed from main report
Works fine
5
With XML data source
Create a xml data source WITHOUT any parameters passed from main report
Failed with "Missing Parameter Values"
6
With XML data source
Create a xml data source WITH a dynamic parameter passed from main report
Failed with "Missing Parameter Values"
I am confused about this issue for a few days, is there any ideas or helps? many thanks!

OK:
We upgraded to CR 13.0.2000.0 and Visual Studio 2012 and .Net Framework 4.5.
Problem still happens.
When we display the report in the designer, the url has parameters. Here are the IIS log entries:

I cannot attach the rpt file here. If you need it, please let me know how to get it to you. I am attaching a screenshot of the datasource location. I am pasting in the striped down .NET code. Any help or pointers would be greatly appreciated.

Missing parameter values message when exporting report

Post Author: Gr_Pr
CA Forum: .NET
Using .NET 2005, CR XI R2, and the Crystal SDK for .NET 2005 to generate reports. Basically CR is my application's reporting tool. So, we create a report in CR XI R2, then distribute that report to our users loading it into the .NET application using the Report Document class.
We have a small problem.
Our user's have the ability to use pre-defined 'prompts' that will pass parameters to the reports. Let's say that the prompt will pass in (5) pre-defined parameter values, but the customer wants to run their own 'custom' report using our prompt, but their 'custom' report contains (6) parameters.
If I let the Report Viewer load the report, the user will be prompted for the missing parameter value that was not supplied by the 'prompt'.
If I run the report without loading it into the Viewer and try to export the report directly to PDF I receive an error message from CR stating I have 'Missing Parameter Values' then the report errors out.
Has anyone come across this? Is there something I missed?
I am not real sure as to why you would be prompted by the Viewer and not by the Export Class. This worked fine when using the RDC component, I was prompted for the missing parameter value by both options.
Any help would be greatly appreciated.

Hi,
The report has it's own ADO Datasource set in crystal reports, so I just pass the log on information to the report object before doing anything else.
this.DataSourceConnections[0].SetConnection("ServerName", "Database", "sa", "Password");
I then do a refresh before applying the parameter values (I do this because the user can preview the report more than one time by using a preview button on the parameter form without re-loading the report object)
this.Refresh();
Then I set all parameter values followed by setting the recordselection formula.

Missing parameter values when trying to export to pdf in C#

HI all,

I'm having a problem passing a parameter from my c#.NET code through Crystal Reports 2008...

Crystal Reports Developer version 12.1.0.892
using a WinXP machine
The parameter I've setted up in Crystal Reports Design is one to dynamically change the query that will run on the report:
"SELECT * FROM REPORTS.{?Protocolname}_FC_QUERY"

Console.WriteLine("Connection opened.");

Console.WriteLine("Connection Properties:");
Console.WriteLine("\tConnection String: {0}", conn.ConnectionString);
Console.WriteLine("\tServerVersion: {0}", conn.ServerVersion);
Console.WriteLine("\tState: {0}", conn.State);
QL_ExportReport("C:\\Data\\converted2crystal\\PLANNING_REPORT_params.rpt");

} catch (OracleException e) {
Console.WriteLine("Error: " + e);
} finally {
conn.Close();
Console.WriteLine("Connection closed.");
}
Console.WriteLine("End of program!");
Console.ReadKey();
}

Can someone please tell me what's the right way passing a parameter to a report?

Thanks in advance.

You should use the
ReportDocument.SetParameterValue("ParameterName", "ParamValue");

Try parsing the parameter value to a decimal value before setting it as parameter value.
Hope this will help
