Some questions on Crystal report's dynamic parameters

With respect to the thread [How can we use C# to read dynamic parameter's value list from .rpt?|How can we use C# to read dynamic parameter's value list from .rpt?].
I have some further questions:
1.How can one differentiate between a Static or Dynamic parameter in a report document using c# code?
2.Is there a way to know what the data source for the dynamic field is, I mean can we know the name of the table which is set to the dynamic field to pull data from?
3. Is there any Report Application Server (RAS) API that allows us to work with dynamic parameter in a report document?
Thanks,
Qin

1.How can one differentiate between a Static or Dynamic parameter in a report document using c# code?
- I'm not aware od any API that will directly tell you that a parameter is dynamic or static.
2.Is there a way to know what the data source for the dynamic field is, I mean can we know the name of the table which is set to the dynamic field to pull data from?
- the only way you can find this out is through RAS. Off the ParameterField class from there is a BrowseField property. If itu2019s a Dynamic parameter, I believe it returns the database field name that it uses to populate the prompt.
3. Is there any Report Application Server (RAS) API that allows us to work with dynamic parameter in a report document?
- See http://help.sap.com/businessobject/product_guides/boexir31/en/rassdk_net_dg_12_en.chm
search for parameters.

Crystal Reports - missing dynamic parameters when published to InfoView

Hi all,
I'm facing a problem when I publish Crystal Reports 2008 V1 which includes dynamic parameters on InfoView (either on BO EDGE 3.1 or Crystal Reports Server 2008 V1). Problem manifests itself in missing dinamic parameters - I get only static parameter panel and need to write in the value by myself... All other documents like Webi, Deski (on BO EDGE) works fine.
I have tried to install all latest Service Pack's for Crystal Reports 2008 V1 but it didn't solve the problem. Btw, Crystal Reports 2008 V1 designer is installed on client machine.
Here are the details of both installations:
BO EDGE 3.1.
OS: Windows Server 2003 SP2
Repository database: MS SQL Server 2005
CR Server 2008 V1
OS: Windows Server 2003 SP2
Repository database: MySQL
Does anyone had a same problem?
I will appreciate any help!
Best regrads

I had the same situation when I changed from a SQL server 2005 data source to a SQL server 2008 data source while using CR 2008. Change printer option default in the report designer to use u201CNo Printer (optimize for screen display) and republish to InfoView. Not sure why this would work, but it resolved the issue for us.

Unable to Save Crystal Reports(With Dynamic Parameters to Infoview)

I am using Crystal Reports 2008 and BOXI 3.1. I have 5 dynamic parameters and can't save my report to Infoview, but If I use Static parameter then I am able to save it.
Any help would be highly interested?
thanks

What is the exact error message and the version of crystal reports.Can you also check that all the BOE services are up and running

Crystal Reports 2008 - dynamic parameters not returing all data

I am having the same issue with Crystal Reports 2008. Only returning 135 customers in a dynamic paramaters when the list should be 3288.
When I re-create the parameter by using a command instead of relying on Crystal to return the data from the db table Crystal returns only 5"pages" of customers to select from.
I have tried to run the report with this reduced selection & it then crashes.
Any ideas??

This article may help you to increase the number of values in the parameter
KBase Article ID:c2017238
Article refers to: Crystal Reports XI BusinessObjects Enterprise XI
Symptom
For performance reasons, in Crystal Reports XI Release 1 and Release 2 the maximum number of values that are returned for a list of values is set to 1000. If you have a cascading List of Values (for example Country > Region > City), the lowest level (in this case City) will only display a maximum of 1000 values. This means that the higher-level prompts may display far fewer values than you expect. The list of values provides the data for the dynamic parameter list.
How can you modify the maximum number of values available in a dynamic parameter list?
Resolution
To increase the maximum number of values available in a dynamic parameter list, you must add a registry key.
CAUTION     The following resolution involves editing the registry. Using the Registry Editor incorrectly can cause serious problems that may require you to reinstall the Microsoft Windows operating system. Use the Registry Editor at your own risk. For information on how to edit the registry key, view the 'Changing Keys and Values' online Help topic in the Registry Editor (Regedit.exe).
It is strongly recommended that you make a backup copy of the registry files (System.dat and User.dat on Win9x computers) before you edit the registry.
Crystal Reports XI Release 1
1.     Create a registry key HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.0\Crystal Reports\DatabaseOptions\LOV.
NOTE     Alternatively, you can create the registry key HKEY_CURRENT_USER\SOFTWARE\Business Objects\Suite 11.0\Crystal Reports\DatabaseOptions\LOV and that key will override the settings of the HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.0\Crystal Reports\DatabaseOptions\LOV key.
2.     Add a string value "MaxRowsetRecords" and set the value to the maximum number of values that you desire for your report. For example, a value of 2000 will return up to 2000 values in the lowest level of a cascading parameter. NOTE: The value 0 (Unlimited) will not work with BusinessObjects Enterprise XI or Crystal Reports Server XI, you must specify another value.
NOTE     The higher the number of values is, the longer it will take the Enter Values dialog box to populate with values.
3.      After making changes to the registry, restart the affected service or application as required.
Crystal Reports XI Release 2
1.     Create a registry key HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.5\Crystal Reports\DatabaseOptions\LOV.
NOTE     Alternatively, you can create the registry key HKEY_CURRENT_USER\SOFTWARE\Business Objects\Suite 11.5\Crystal Reports\DatabaseOptions\LOV and that key will override the settings of the HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.5\Crystal Reports\DatabaseOptions\LOV key.
2.     Add a string value "MaxRowsetRecords" and set the value to the maximum number of values that you desire for your report. For example, a value of 2000 will return up to 2000 values in the lowest level of a cascading parameter.
NOTE     The value 0 (Unlimited) will not work with BusinessObjects Enterprise XI or Crystal Reports Server XI, you must specify another value.
3.     After making changes to the registry, restart the affected service or application as required.

I'm getting the below issue when I try to deploy a report with Dynamic parameters, when I deploy it with static parameters I'm not getting this issue.

I’m getting the below issue when I try to deploy a crystal report with Dynamic parameters in BI Launch Pad, when I deploy the same report with static parameters I can deploy and run it. I have Restarted the BI server, still the issue exitno use. kindly help me on this issue.
“This error occurred: Adding Crystal Report "CrystalReport1.rpt" failed. The server with kind rptappserver returned an error result. Failed to copy the report file to the report object. Refreshing the report object properties might have failed. Failed to read data from report file CrystalReport1. Reason: Failed to read parameter object”.

BO does not run dynamic params through the report as would happen without BusinessObjects (BO) or Crystal Reports Server (CRS). When you publish a report with dynamic parameters to BO/CRS, the prompt is published to the repository so that it can be accessed through the Business View Manager (which can be installed as part of the client tools). In order for this to work a couple of things need to happen:
1. You need to be sure that you check the "Update Repository" box on the Save As screen the first time you publish the report.
2. Your BO/CRS user needs to have "view" access to the Crystal2013ReportApplicationServer in the Servers section in the CMC - in fact, the Everyone group should be given view access to the server in order for dynamic prompts to work correctly.
3. In the Business View Manager, the Administrator user needs to give your user, or, even better, a Crystal Developers group full control access to the "Dynamic Cascading Prompts" folder.
Best practice for dynamic prompts in a BO/CRS environment is to actually create the prompts in the Business View Manager. This will allow you to create a single data connection that can be reused and also create lists of values such that the same list or prompt can be reused by multiple reports. If you just create the prompts in Crystal, you will end up with multiple data connections to the same database, the prompts will use the whole query for the reports to get the dynamic values instead of just a focused query to the lookup table that contains the values, and there ends up being lots of duplication and chaos.

Crystal Report Viewer Credential Prompt for Report with Dynamic Parameters

The .NET Crystal Report Viewer is prompting for database credentials when launching a report containing dynamic parameters. This only occurs for reports created with SAP Crystal Reports 2011 designer. Reports created with Crystal Reports XI designer (where dynamic parameters were first introduced) work correctly.
The credential prompt window contains the following fields:
- Server Name: <server name> (disabled)
- Database Name: <database name> (disabled)
- User Name: <empty> (enabled)
- Password: <empty> (enabled)
- Use Single Signon Key: false (disabled)
The values in the prompt window which are disabled are the database connection values used during the design of the report in the SAP Crystal Reports 2011 designer.
Expected Result:
- No prompt for database credentials.
- Values read from the database should be populated in a drop down for the dynamic parameters.
Environment:
- Visual Studio 2010 (C#)
- Windows 7 Enterprise
- SAP Crystal Reports runtime engine for .NET Framework 4
- SAP Crystal Reports, version for Visual Studio 2010
- SAP Crystal Reports 2011
The database connection is being set to use a DSN. It must be a DSN as the calling application is only aware of the DSN/Username/Password values. These values are being passed to the Crystal Report Viewer contained in a Windows form.
The database connection for the report is being set as follows:
foreach (InternalConnectionInfo internalConnectionInfo in this.report.DataSourceConnections)
    // Must set the UseDSNProperties flag to True before setting the database connection otherwise the connection does not work
    if (internalConnectionInfo.LogonProperties.ContainsKey("UseDSNProperties"))
        internalConnectionInfo.LogonProperties.Set("UseDSNProperties", true);
    // Supposed to set the database connection for all objects in the report (ie. main report, tables, sub reports)
    internalConnectionInfo.SetConnection(this.DSN, string.Empty, this.LoginName, this.Password);
The SetConnection method's signature is as follows:
   SetConnection(string server, string database, string name, string password)
As you can see from the code snippet above I am setting the DSN name as the server parameter, blank for the database parameter (a database connection using DSN should only require DSN name/Username/Password) and the database username and password respectively.
Is this a SAP bug?
Is this the correct way of setting the database connection to use a DSN?
Is there some other properties that need to be set somewhere else in the report through code?
Any help would be greatly appreciated.

Thanks for the pointer to the database connection code generator. After taking a look at the output from the tool I was able to finally get the dynamic parameters to load and populate properly without prompting for credentials. I needed to tweak the outputted code a bit to match my requirements of using a DSN only connection.
Instead of updating the database connection properties contained within the Report.Database.Tables collection from the CrystalReports.Engine namespace, I changed it to replace the database connection properties in the Report.ReportClientDocument.DatabaseController.Database.Tables collection from the CrystalDecisions.ReportAppServer.DataDefModel namespace. For one reason or another, using the RAS namespace solved the problem.
Below is the updated code with the change made:
using RAPTable = CrystalDecisions.ReportAppServer.DataDefModel.Table;
foreach (InternalConnectionInfo internalConnectionInfo in this.report.DataSourceConnections)
    // Must set the UseDSNProperties flag to True before setting the database connection
    if (internalConnectionInfo.LogonProperties.ContainsKey("UseDSNProperties"))
        internalConnectionInfo.LogonProperties.Set("UseDSNProperties", true);
    // Sets the database connection for all objects in the report (ie. main report, tables, sub reports)
    internalConnectionInfo.SetConnection(this.DSN, string.Empty, this.LoginName, this.Password);
// The attributes for the QE_LogonProperties which is part of the main property bag
PropertyBag innerPropertyBag = new PropertyBag();
innerPropertyBag.Add("DSN", this.DSN);
innerPropertyBag.Add("UserID", this.LoginName);
innerPropertyBag.Add("Password", this.Password);
innerPropertyBag.Add("UseDSNProperties", "true");
// The attributes collection of the tables ConnectionInfo object
PropertyBag mainPropertyBag = new PropertyBag();
mainPropertyBag.Add("Database DLL", "crdb_ado.dll");
mainPropertyBag.Add("QE_DatabaseType", "OLE DB (ADO)");
mainPropertyBag.Add("QE_LogonProperties", innerPropertyBag);
// Pass the database properties to a connection info object
ConnectionInfo connectionInfo = new ConnectionInfo();
connectionInfo.Attributes = mainPropertyBag;
connectionInfo.Kind = CrConnectionInfoKindEnum.crConnectionInfoKindCRQE;
connectionInfo.UserName = this.LoginName;
connectionInfo.Password = this.Password;
// Replace the database connection properties of each table in the report
foreach (RAPTable oldTable in this.report.ReportClientDocument.DatabaseController.Database.Tables)
    RAPTable table = new RAPTable();
    table.ConnectionInfo = connectionInfo;
    table.Name = oldTable.Name;
    table.QualifiedName = oldTable.QualifiedName;
    table.Alias = oldTable.Alias;
    this.report.ReportClientDocument.DatabaseController.SetTableLocation(oldTable, table);
this.report.VerifyDatabase();
Thanks again Ludek for the help.

How to create user editable Crystal Report with dynamic dataset

What I would like to achieve:
A program loads a report in runtime updates list of database fields (possibly includes sample data), open report in "Crystal Reports 2011" (or 2008) where user customizes report and saves it. Later on the program loads the report, fills actualized data and displays it in .net report viewer.
What I do:
CrReport = New CrystalDecisions.CrystalReports.Engine.ReportDocument
CrReport.Load(TemplateFilename)
Dim Results As DataTable
DataTable is filled from a database
CrReport.SetDataSource(mResults)
CrReport.SaveAs(NewReportPath, True)
The NewReportPath is opened in the default program.
What are the problems
The report is open in preview mode (not in design).
When the field is added to the report the designer asks for XML datasource on preview.

The short answer is that it is not possible. I broke the question to other two: How to save a report that it opens without preview? and How to create user editable Crystal Report with dynamic dataset, where it is possible to find details. Key answer is Re: How to create an editable previewable report?

How to schedule a report with dynamic parameters

We need to schedule a Webi report with dynamic parameters then email the different result to different email groups. Is it possible to do this in scheduler? Please advise. Thanks.

there are 2 schedulers
1st CMS
the reports which does not have any input parameters, only then t can be scheduled in CMS
2nd in Infoview
if report has input parameters and if you want to schedule it, then you may need to schedule the report from Infoview

Dynamic command execution fails in Crystal report viewer for parameters

We are using the Crystal Report Viewer for the .Net Application on the client side.The reports are designed using Crystal Report XI R2.
The issues that we are currently encountering is that, we are unable to load the combo-boxes in the pop-up for the parameters.
All the reports have multiple commands and the variables are of 'dynamic' type.
When the dialog box for requesting the pop-up comes up, It comes up empty even though they are linked to the respective commands.
Also,For reports having multiple parameters we are unable to give a single dialog box to get in all the parameters.It appears as a series of prompts.
Both,these issues are not encountered when the reports are launched via the Crystal reports developer tool.

Hello Varun,
I recommend to post this questionin the [dedicated NET forum|SAP Crystal Reports, version for Visual Studio;.

Bapi Function call from Crystal reports 2008. import parameters syntax.

Dear,
I have an issue with calling a function directly from Crystal reports (2008) in the R3 system.
(if this belongs in another thread , please add the link if moved !)
I try to get data through function "BAPI_CLASS_GET_CLASSIFICATIONS".
Till now all possible input parameters have no data-result.
I already read other threads stating that 'for example' the Language key needs to be provided in a single character. 'E' in stead of 'EN'.
I also already created a Z-wrap-function that fills out all input parameters 'hardcoded'. This works.
clearly there are som syntax changes in passing the values to R3 when called from Crystal Reports.
Can someone state which syntax has to be followed for numeric fields, for datefields etc. (so when i make these dynamical, I know which syntax should be the outcome of the formula)
in my function that doesn't work I use these selections:
(this function is called in a standard report only calling this function)
{BAPI_CLASS_GET_CLASSIFICATIONS_1.I_LANGU_ISO} = "E" and
{BAPI_CLASS_GET_CLASSIFICATIONS_1.I_LANGU_INT} = "E" and
{BAPI_CLASS_GET_CLASSIFICATIONS_1.T_CLASS_OBJECTS.OBJECT_TYPE} = "MARA" and
{BAPI_CLASS_GET_CLASSIFICATIONS_1.T_CLASS_OBJECTS.OBJECT_KEY} = "000000000000000085" and
{BAPI_CLASS_GET_CLASSIFICATIONS_1.I_CLASSNUM} = "DSWTEST" and
{BAPI_CLASS_GET_CLASSIFICATIONS_1.I_CLASSTYPE} = "001" and
{BAPI_CLASS_GET_CLASSIFICATIONS_1.I_KEY_DATE} = Date (2011, 08, 05)
I already tried other languages or the 'EN' as input.
(I would like to know how the date is passed exaclty to R3.)
The function is of course RFC enabled.
when I call the my Z-function with predefined inputparameters in R3 it does give the wanted result.
FUNCTION ZBAPI_CLASS_GET_CLASSIFICATION.
""Local Interface:

ENDFUNCTION.
please advise.
once again if this should be moved to another forum , add the link please!

Dear,
I just debugged my Z-function, after adding all input parameters as in the standard BAPI function.
All parameters seems to be passed correctly except from the table parameters from
CLASS_OBJECTS
So all I_parameters are passed :
{ZBAPI_CLASS_GET_CLASSIFICATION.I_LANGU_INT} = "EN" and
{ZBAPI_CLASS_GET_CLASSIFICATION.I_LANGU_ISO} = "EN" and
{ZBAPI_CLASS_GET_CLASSIFICATION.I_KEY_DATE} = Date (2011, 08, 05) and
{ZBAPI_CLASS_GET_CLASSIFICATION.I_CLASSNUM} = "DSWTEST" and
{ZBAPI_CLASS_GET_CLASSIFICATION.I_CLASSTYPE} = "001" and
{ZBAPI_CLASS_GET_CLASSIFICATION.I_CHARACTS_OF_CLASS_ONLY.BAPIFLAG} = ""
but the table parameters aren't coming through:
{ZBAPI_CLASS_GET_CLASSIFICATION.T_CLASS_OBJECTS.OBJECT_TYPE} = "MARA" and
{ZBAPI_CLASS_GET_CLASSIFICATION.T_CLASS_OBJECTS.OBJECT_KEY} = "000000000000000085" and
these are 'blanco' in the function.
also after the function is executed and all data is retrieved, when passing the data back to Crystal reports, once again, the table result isn't passed to Crystal Reports.
please advise

Creating crystal report file dynamically.

Post Author: malcomstewart115
CA Forum: General
Hi, everybody.
I have one problem.
How to create crystal report file(*.rpt) in php dynamically.
I mean, I want to create the "*.rpt" file with php code.
Please help me. thanks everybody.

Post Author: PWilkens
CA Forum: General
It sounds like you're defeating the power and purpose of Crystal Reports, or replace it with pure PHP (which I suppose could be done... but why?)
What exactly are you trying to do?
If you're trying to make certain parts of the report hide or reveal or change depending on variables settings in the PHP file, that's easy enough to accomplish by sending parameters with your PHP values into the report. But the dynamic actions really need to be done within the report itself, accomplished through ample use of the section and field settings provided within the Report Designer.
