Missing Parameter Values CR2008 Optional Parameter

Hi,
I am getting "Missing Parameter Values" error
"CrystalDecisions.CrystalReports.Engine.ParameterFieldCurrentValueException: Fehlende Parameterwerte. ---> System.Runtime.InteropServices.COMException (0x8004100E)"
if I try to export a Report with an optional Parameter without setting the parametervalue.
The Report works fine with ReportViewer.
If I uncomment the "Parameterpart" and set a parametervalue it works fine, but it should works without a parametervalue too, its optional.
I have tried many for a long time and read many Websites but it does not work !
I use WinXP SP2 CR2008 with C# .NET 2.0 VS2005
CrystalDecisions.CrystalReports.Engine.dll version 12.0.2000.683 Date: 2008-03-01
CrystalDecisions.Shared.dll version 12.0.2000.683 Date: 2008-03-01
Sorry my English is very Bad !
Thanks a lot!

RecordSelectionFormula in Report:
(not HasValue({?Land}) OR {tab.location_code} = {?Land}) and
{tab.sup} = "XXX" and
{tab.Accounting_Period} = "200801"

You need to be careful when using optional parameters. If you are using the optional parameter in a record selection formula you'll need to check and make sure it has a value before you use it. There is a function call HasValue() that you can use to do this.
If you have an optional parameter in the record selection formula and you don't pass a value you'll need to make sure your selection formula can be completed with out it.
This is an excerpt from our help file.
Crystal Reports supports optional parameters. An optional parameter is a prompted value that does not have to be supplied by the user.
Report designers should provide some guidance to the end user that a parameter is optional by adding this information to the prompt text.
Optional parameters are treated by Crystal Reports as optional anywhere within the report that they are used. You cannot set one instance of the parameter to optional and another to mandatory.
Note: After you set a parameter to optional, if you use the Select Expert, the system will automatically add the selection formula for you using the HasValue() function.
The Formula Workshop Editor does not automatically add the formula. Only the Select Expert automatically adds the formula for you.
If you change the parameter from optional to mandatory, the HasValue() function is not automatically removed from your formula.
Handling a parameter with no value
When the report engine evaluates any formula which references an optional parameter that does not have a value, it generates a runtime error. All formulas that reference an optional parameter should first use the HasValue() function to check if that parameter has a value before evaluating it. This includes record selection formulas and saved data formulas.
Note: The system will not automatically drop a statement from the SQL WHERE clause. It is the report designeru2019s responsibility to decide which statement to leave out based on HasValue() testing.

  • Error: Missing Parameter Values on

    I've started experiencing the "Missing Parameter Values" error on a report containing a subreport. All of my other reports can export just fine, but just not the one with the subreport. The report (and the subreport) both use a stored procedure to retrieve their data, with 4 parameters. The first three parameters are linked directly from the report to the subreport. The 4th parameter is optional, and is linked to the subreport with a Formula Field.
    When I delete the subreport, the report exports just fine, so the issue is definitely with the subreport ?configuration?
    I'm using Visual Studio 2005, with Crystal Reports for VS 2005. I've been searching the forums, and I downloaded and installed a package: crnet20win32x86_en_chf.zip, but it didn't solve my problem. Just to be sure, I restarted and installed it with nothing running, in case that could be a factor.
    Is there anything I can do to work through this? Any other fix I'm missing?
    Thanks

    Thanks for the tip. I did that just now, and I found the [Hot Fix|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333233313339333533393334%7D.do]
    That particular Hot Fix describes my situation exactly, in that a report Stored Procedure parameter is "supposed" to be passed on to the Subreport. However, the Hot Fix describes prompting, which isn't occurring in my case, since I'm exporting the report entirely in code. My situation is just the error, Missing Parameter Values.
    In any case, I've already run that entire Hot Fix package (twice), and I've found that I have 2 of the crpe32.dlls. Neither one is the version specified in the Hot Fix, (Version 10.2.0.1256). The second dll listed below seems to be of a version prior to the Hot Fix, I don't know if it could be the reason why it still doesn't work after applying the Hot Fix.

    I've checked all the versions of references in my projects, and they all reference the 2.7 dlls, but I'd like to know if there is a way to replace the 2.5 version, just in case.
    As far as the other search results, they hinted at things I've already tried. What else can I try?

  • Missing Parameter Values - I'm not using parameters linking to sub

    I'm developing reports for use in an aspx environment using Visual Studio 2010 and CR 13.
    I have a main report and a subreport. Each report is linked to the database with a view that is connected to a dataset.
    When I place the subreport in the main report I edit the change links option and select identical fields from each report.
    When I run the code with the subreport commented out I get what I expect on the page.
    When I uncomment the subreport I get "Missing parameter values"
    Here's the code that I uncomment for the subreport. I've already checked to ensure that there is data in the dataset.
    mySection = CaseAssignmentRpt.ReportDefinition.Sections("dsCaseOffender")
    mySubObj = mySection.ReportObjects("srCaseOffender")
    mySubRep = mySubObj.OpenSubreport(mySubObj.SubreportName)
    mySubRep.SetDataSource(dsCaseAoffender)
    Do I need to do anything special to my dataset for the two fields to get linked?

    Hi Chris
    Nothing special needed - just making sure that the data is exactly what the report and subreport expect. It is quite typical for this issue to come up if the dataset contains date that is not as expected (e.g.; field formats (including nulls / spaces, etc, missing fields, and so on).

  • 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" error on Export

    Hi,
    I am getting "Missing Parameter Values" error if all required parameter values are not passed in the report through application. Same error is not coming when all the parameters are passed.
    And parameter window also not displaying if all parameters are not passed to the report for export option. (Parameter window displaying on preview option if all the parameters are not supplied).
    I have tried both Report Viewer's ExportReport function & ReportDocument's Export function. But both are results same.

    Given example is not working as expected.
    1) Calling of  ExportReport() function invokes the file Save As window to save the exported file eventhough exported path & file name supplied in the program.
    2) After accepting the output file name, "Missing parameter values" error coming instead of displaying Crystal's Parameter window.
    Below is the piece of code to export the output. I am calling Export() function if all the parameters are supplied by the application otherwise i am calling Viewer's ExportReport() fuction. Please have a look and let me know if any code change is required.

  • "Missing parameter value" error on autoprinting with CR layout

    Hi all, i had recently run into the following:
    document layouts that work perfectly from preview and after adding a document, dont work if the document is auto printed on add.
    Gives an error:
    missing parameter value
    And in system messages log:
    Error during printing: ensure all parameter values are defined.
    With only @dockey token  present in the layouts (so no other parameter).
    What makes me wonder is that this doesn't happen to all the layouts, most of them works perfectly the same way (only dockey parameter, autoprint is set etc.) but the stock related documents do this on add.
    Any ideas?
    I found a likely issue in note 1466274 but it's listed as fixed in 8.8 PL 13, we are on PL 15. Could reproduce on PL 18.
    Thanks and regards.

    Hi Gordon.
    I could reproduce on the test copy of the db even on different patch levels.
    Can this be the almost same issue as stated in the note? I mean same code problem but at another point?
    Yesterday i found another example:
    uppon exiting the dunning wizard with print and exit option allmost the same error. The difference is that beforehand the same error messages one pops up with the following:
    title:Crystal Reports Windows form viewer
    "A report application server meghibásodott." (this is even with sap b1 gui langugage set to english)
    "The Report application server crashed/broke down(?)"
    Will try to test it on the demo database now..
    Any ideas?

  • "Missing parameter values."  --  Export and Print only...

    I have a web application and I am using CrystalReportViewer.  I am passing several parameters to Crystal using: 
    report.SetParameterValue(field.Name, Session[field.Name]);
    I have session variables which will hold parameters needed to pass into the report.  The session variables are populated from controls on my webpage after an onclick event.  This even not only populates session, but also passes parameters to the report with the following code: 
    ReportDocument report = new ReportDocument();
    Session["MapPathName"] = "./Reporting/CaseStudy.rpt";
    report.FileName = Server.MapPath(Session["MapPathName"].ToString());
    ParameterFields fields = new CrystalDecisions.Shared.ParameterFields();
    fields = report.ParameterFields;
    foreach (ParameterField field in fields)
          report.SetParameterValue(field.Name, Session[field.Name]);
    CrystalReportViewer1.ReportSource = report;
    This works great for reporting and is very extensible.  However, when clicking on the "Print" or "Export" buttons on the toolbar I get "Missing parameter values."  I attempted to export manually in code using the .ExportToStream function but I still get the error, "Missing parameter values." 
    I received this error also in Refresh, Search, and Navigate functions.  This was corrected by calling a function that supplies the above code block to these functions.  However, I do not see any events for controlling the Print nor the Export events. 
    QUESTION: How can I print or export a report when passing parameters using CrystalReportViewer?  Thanks in advance!

    There are no Export or Print events accessible for the viewer
    Since it sounds like you are creating the reportdocument object in your click event, the settings on this object become out of scope on successive postbacks executed by other events.
    to get around this without major changes, you can place your "report" object in session in this event and retrieve it from session on successive postbacks.  This should solve your problems around navigation, printing and exporting.  What you will need to do is check if the session object exists (usually in page_load or page_initialze) and if so, retrieve it from session and bind it to the viewer's reportsource.  If the session object does not exist, then do nothing (ie you have not clicked your button yet that retrieves the parameter values from session and loads the report).  Also, in your click event you can check if the report session object exists and if so, remove it so that it can be re-created with your new parameter values (ie i'm assuming the only time you want to set parameter values is in this event).

    Please anyone give me an idea what is causing the problem.
    Thanks,

    in DAC > Run History > Task Details, query
    Name = SDE_ORA_Product_Category_Temporary
    Open Status Description, look for string -lpf, the file after it is the actual parameter file DAC send to INFA server. E.g

    Open the parameter file, most likely the [session_name] does not match with SDE_ORA_Product_Category_Derive_Full or some parameters are missing.

  • Use of layout when more than one parameter - Error Missing Parameter Values

    Hi,
    Is it possible to use a crystal report which has more than one parameter as the layout for the bill of materials report.
    I have 3 parameters
           1. DocKey@       The Bill of Materials to be printed
           2. Number of levels to be printed
           3. type of levels to print.
    When I try to print it gives me the error Missing Parameter Values.
    I have tried changing the DocKey@ to CodeKey@ but the same error.
    Does anyone now where to find a list of these tokens?
    Thanks
    Chris

    I looked at the crystal report conversion to try to find what parameters it used and found none.
    I have managed to create and use a crystal report to replace the production order using DocKey@ as the parameter.  This works within SAP.  However I have converted the system production order to crystal reports and from the converted report I cannot see any parameters at all.
    How and where can you find out what paramters you need to use to replace any PLD report?  Several reports have multiple selection criteria before the report prints.  How can you find out what their tokens are called?  I am starting to pull my hair out.  I am getting great help from this forum, but do you know any documentation which actually explains this area.
    Thanks

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

  • ReportDocument.ExportToStream raises "Missing Parameter Values" exception

    Hi,
    I have a web app built using VS 2008 which runs many reports developed in CR 2008. Most of these reports take parameters and many have embedded subreports. Many of the reports can either be viewed directly or e-mailed. For the latter, I use ReportDocument.ExportToStream(ExportFormatType.PortableDocFormat) to export a PDF file which then gets attached to the e-mail.
    One set of reports works fine when viewed directly, but raises a "Missing Parameter Values" exception when I try to generate the PDF.  All the other reports, seemingly similar in most respects, including the number and type of parameters, work fine when calling ExportToStream.
    Here is the really strange part: the exception is spurious. I wrapped the whole thing in a try/catch block to better examine the exception, hoping to find which parameter value is actually missing.  I could not identify the missing parameter value, but once I handled the exception, the report runs fine and converts to PDF.
    Any hints as to what could be causing this problem?  It seems like a really bad hack to solve the problem using a try/catch in this way.
    Thanks.
    Dan

    Thanks for the quick response. Your code was very instructive, but did not help yet.  Here is what I have:
    (This response is too long for a single post, so I will split it and finish in the next post.)
    ReportDocument rptDoc = new ReportDocument();
    rptDoc.Load(strReportSourceFolder + strReportName + ".rpt");
    rptDoc.SetParameterValue("ClientID", lngKeyFieldID);
    rptDoc.SetParameterValue("Role", "Client");
    This is followed by an amazing chunk of code, provided to me by a guy at SAP Tech Support, who said it was necessary to pass database credentials programatically.  It iterates the tables in the ReportDocument and individually sets the LogonInfo. (I say "amazing" because it astounds me you have to jump through such hoops for something that should be routine and easy.)  The commented lines are just to help in debugging.
    ConnectionInfo conn = new ConnectionInfo();
    conn.ServerName = "myServer";
    conn.DatabaseName = "myDB";
    conn.UserID = "myUserID";
    conn.Password = "myPassword";
    Tables tables = rptDoc.Database.Tables;
    foreach (Table table in tables)
      //string str= table.TestConnectivity().ToString());
      TableLogOnInfo tableLogonInfo = table.LogOnInfo;
      tableLogonInfo.ConnectionInfo = conn;
      table.ApplyLogOnInfo(tableLogonInfo);
      //table.Location = table.Location;                        
    This is followed by the viewer stuff:
    CrystalReportViewer1.DisplayGroupTree = false;
    CrystalReportViewer1.DisplayToolbar = true;
    CrystalReportViewer1.HasToggleGroupTreeButton = false;
    CrystalReportViewer1.HasToggleParameterPanelButton = false;
    CrystalReportViewer1.Page.Title = strReportName;
    CrystalReportViewer1.ReportSource = rptDoc;
    Up to here, it works fine, displaying the report.  If the report is also to be e-mailed, the following is executed:
    if (bEmail)
      //  export to PDF, then mail that
      SmtpClient client = new SmtpClient();
      MailAddress from = new MailAddress(ConfigurationManager.AppSettings["ReportMailFrom"].ToString());
      MailMessage message = new MailMessage();
      message.From = from;
      message.SubjectEncoding = System.Text.Encoding.UTF8;
      message.Subject = "E-mail BackOffice report: " + strReportName;
      try
        foreach(ParameterField field in rptDoc.ParameterFields)
          Logger.LogEvent("test", "", field.ToString(), "Trace", null, true, true);
          Logger.LogEvent("test", "", "Name: " + field.Name, "Trace", null, false, false);
          Logger.LogEvent("test", "", "PromptText: " + field.PromptText, "Trace", null, false, false);
          Logger.LogEvent("test", "", "IsOptionalPrompt: " + field.IsOptionalPrompt, "Trace", null, false, false);
        MemoryStream memStream = (MemoryStream)rptDoc.ExportToStream(ExportFormatType.PortableDocFormat);
        Attachment data = new Attachment(memStream, MediaTypeNames.Application.Pdf);
        ContentDisposition disposition = data.ContentDisposition;
        disposition.CreationDate = DateTime.Now;
        disposition.ModificationDate = DateTime.Now;
        disposition.FileName = strReportName + ".pdf";
        disposition.DispositionType = DispositionTypeNames.Attachment;
        message.Attachments.Add(data);
      catch (Exception ex)
        Logger.LogEvent("error", "Page_Load", strReportName + " Exception: " + ex.Message, "Trace", null, true, true);
      //  ...  do the rest of the stuff to create & send the e-mail
    (The rest of this message will be in the following post.  Sorry it is so long.)

  • Crystal Runtime exception: Missing parameter values

    Our company did a PeopleTools upgrade at one of our clients recently. We upgraded them to PeopleTools 8.50.08. We had to convert all the Crystal Reports to the 2008 format using the RPT converter which is included in the Client install of PeopleTools.
    The only problem now is that a lot of the Crystal processes in PeopleSoft are failing with the following error:
    Crystal Runtime exception: Missing parameter values.
    I've checked the parameters which are being passed to the report and I see both parameters are filled:
    E:\HR881\BIN\CLIENT\WINX86\PSCRRUN.EXE -CTORACLE -CDHRMKPDEV -COPSDUT -CPOPRPSWD -I218609 -RP"PUP202K" -OT6 -OP"G:\PS\PSPRCS\log_output\HRMKPDEV\CRW_PUP202K_218609" -LGDUT -OF2 -ORIENTL "2000-10-01" "2002-06-30"
    Database type is Oracle. HRMS version is 8.8. I can run the Query which gets the data in just fine and I can also run the report from Crystal fine. This only happens with Crystal reports which have a date field as a parameter/prompt in the report.
    There's currently an SR open at Oracle, but I was hoping that someone here can help me nail this issue. I'm not too happy with the quallity of Oracle support, but that's a whole different story.

    <s>Just to be sure, did you put a space after each parameter name or is it a typo over here ?
    E:\HR881\BIN\CLIENT\WINX86\PSCRRUN.EXE -CT ORACLE -CD HRMKPDEV -CO PSDUT -CP OPRPSWD -I 218609 -RP "PUP202K" -OT 6 -OP "G:\PS\PSPRCS\log_output\HRMKPDEV\CRW_PUP202K_218609" -LG DUT -OF 2 -OR IENTL "2000-10-01" "2002-06-30"</s>

    sorry, it was wrong assumption.

  • Error printing Check - "Missing Parameter Values. Error During Printing"

    Dear friends,
    Our client is in SAP B1 8.81 Pl07 and is facing an error while printing checks designed in Crystal Reports. As soon as they click on "Print" button, we are getting an error "Missing Parameter Values. Error During Printing".
    We have checked the Crystal Reports and all the parameters are given.
    Can anyone help me regarding this?
    Thanks and regards,

    hi,
    Quoted from Note 1555170
    1555170 - Error 'Missing parameter values' printing with CR layout
    Symptom
    When you print on add any stock transactions document, with Crystal report layout, you receive error message:'Missing parameter values' and then 'Error during the printing; ensure all parameters are defined'
    Step by Step scenario:
    1.Go to Administration / System Initialization / Print preferences and select the tab per document.
    2.Select the document stock transfer and tick the box print document when adding document and click on update.
    3.Go to stock management / stock transactions / stock transfer
    set the Crystal report template as default.
    Note:
    - The issue is reproduced also for Goods Receipt and Good Issue.
    - The issue is reporduced with any Crystal Report Template  for the     above documents.
    Cause
    Program error
    Solution
    This issue is candidate for a change in a future release of SAP Business One.
    Workarounds:
    1.Use PLD for printing the stock transactions.
    2.Convert the PLD layout to Crystal reports with Crystal converter.
    3.Print the document after adding it.
