Changing Crystal report connection - another question

Hi All,
I have to change the conneciton for crystal reports that resides on the CMC.
I saw some code examples that looks promising, but I encountered some problems in opening the report as a ReportClientDocument ocbject.
I use the following code:
IReportAppFactory rptAppFactory = (IReportAppFactory) enterpriseSession.getService("", "RASReportService");
IInfoObjects objs=iStore.query("SELECT * FROM CI_INFOOBJECTS WHERE SI_KIND='" + CeKind.CRYSTAL_REPORT);
    Iterator objsIter = objs.iterator();
    ReportClientDocument rcd = null;
    while(objsIter.hasNext()) {
        Object obj = objsIter.next();
        rcd = rptAppFactory.openDocument((IReport)obj, OpenReportOptions._discardSavedData, Locale.getDefault());
But I get an error when trying to open the document:
Caused by: java.lang.NoSuchMethodError: com.crystaldecisions.proxy.remoteagent.ICommunicationAdapter.setProductLocale(Ljava/util/Locale;)V
     at com.crystaldecisions.sdk.occa.managedreports.ras.internal.RASReportAppFactory.a(Unknown Source)
     at com.crystaldecisions.sdk.occa.managedreports.ras.internal.RASReportAppFactory.a(Unknown Source)
     at com.crystaldecisions.sdk.occa.managedreports.ras.internal.RASReportAppFactory.openDocument(Unknown Source)
     at com.crystaldecisions.sdk.occa.managedreports.ras.internal.RASReportAppFactory.openDocument(Unknown Source)
Well, the object IReportAppFactory is from cereports.jar library, and the ICommunicationAdapter is from CrystalReportsRuntime.jar library
Can anyone please help with that issue please ?
I just have no idea what's going on there...

Hi
I am trying to do the same thing......
try substituting rcd = rptAppFactory.openDocument((IReport)obj, OpenReportOptions._discardSavedData, Locale.getDefault());
for
rcd = rptAppFactory.openDocument((IInfoObject)obj, OpenReportOptions._discardSavedData, Locale.getDefault());
or something like this:
while(objsIter.hasNext()) {
IInfoObject obj = (IInfoObject) objsIter.next();
rcd = rptAppFactory.openDocument((obj, OpenReportOptions._discardSavedData, Locale.getDefault());

Question on crystal report connections

Hi,
Not sure if i'm at e right forum. But I have this question, can anyone help me with it?
I'm developing on ASP .Net 2.0 + Crystal report (Version=10.2.3600.0), I got to know that my client actually only have license to run Crystal report with concurrently of 3 max active connection per time.
Is there anyway to detect the number of connections currently being used? Or anyway to return a significant error/status to inform user that there is no active connection available for usage at e moment?
Either that, or how crystal report actually determine the number of connections?
Thanks in advance.

Thanks for the answer.
But it will be better if i can know what is the return error code or status when the crystal report(CR) hits the max (of 3 concurrent user). I been searching high and low for it, but failed to do so.
I was hopeing that I can create a function or something to detect the error code or status return when CR hits its max.
I'm developing on VS 2005 With crystal report, which comes along with it. If i'm not wrong its CR 9. Correct me if I got e versioning wrong. =)
Any idea?

Hi Vangelis,
Here's a simple VB class that has functions for setting the login details for the report and passing parameters.
Option Strict Off
Option Explicit On
Public Class CrystalFunctions
    Enum ParamType As Integer
        Int
        Text
    End Enum
    Public Shared Sub SetCrystalLogin(ByVal sUser As String, ByVal sPassword As String, ByVal sServer As String, ByVal sCompanyDB As String, _
           ByRef oRpt As CrystalDecisions.CrystalReports.Engine.ReportDocument)
        Dim oDB As CrystalDecisions.CrystalReports.Engine.Database = oRpt.Database
        Dim oTables As CrystalDecisions.CrystalReports.Engine.Tables = oDB.Tables
        Dim oLogonInfo As CrystalDecisions.Shared.TableLogOnInfo
        Dim oConnectInfo As CrystalDecisions.Shared.ConnectionInfo = New CrystalDecisions.Shared.ConnectionInfo()
        oConnectInfo.DatabaseName = sCompanyDB
        oConnectInfo.ServerName = sServer
        oConnectInfo.UserID = sUser
        oConnectInfo.Password = sPassword
        ' Set the logon credentials for all tables
        For Each oTable As CrystalDecisions.CrystalReports.Engine.Table In oTables
            oLogonInfo = oTable.LogOnInfo
            oLogonInfo.ConnectionInfo = oConnectInfo
            oTable.ApplyLogOnInfo(oLogonInfo)
        Next
        ' Check for subreports
        Dim oSections As CrystalDecisions.CrystalReports.Engine.Sections
        Dim oSection As CrystalDecisions.CrystalReports.Engine.Section
        Dim oRptObjs As CrystalDecisions.CrystalReports.Engine.ReportObjects
        Dim oRptObj As CrystalDecisions.CrystalReports.Engine.ReportObject
        Dim oSubRptObj As CrystalDecisions.CrystalReports.Engine.SubreportObject
        Dim oSubRpt As New CrystalDecisions.CrystalReports.Engine.ReportDocument
        oSections = oRpt.ReportDefinition.Sections
        For Each oSection In oSections
            oRptObjs = oSection.ReportObjects
            For Each oRptObj In oRptObjs
                If oRptObj.Kind = CrystalDecisions.Shared.ReportObjectKind.SubreportObject Then
                    ' This is a subreport so set the logon credentials for this report's tables
                    oSubRptObj = CType(oRptObj, CrystalDecisions.CrystalReports.Engine.SubreportObject)
                    ' Open the subreport
                    oSubRpt = oSubRptObj.OpenSubreport(oSubRptObj.SubreportName)
                    oDB = oSubRpt.Database
                    oTables = oDB.Tables
                    For Each oTable As CrystalDecisions.CrystalReports.Engine.Table In oTables
                        oLogonInfo = oTable.LogOnInfo
                        oLogonInfo.ConnectionInfo = oConnectInfo
                        oTable.ApplyLogOnInfo(oLogonInfo)
                    Next
                End If
            Next
        Next
    End Sub
    Public Shared Sub SetCrystalParams(ByVal sFieldName As String, ByVal iDataType As ParamType, ByVal sVal As String, ByRef oRpt As CrystalDecisions.CrystalReports.Engine.ReportDocument)
        Dim oFieldDefs As CrystalDecisions.CrystalReports.Engine.ParameterFieldDefinitions
        Dim oFieldDef As CrystalDecisions.CrystalReports.Engine.ParameterFieldDefinition
        Dim oParamVals As CrystalDecisions.Shared.ParameterValues
        Dim oDiscreteVal As CrystalDecisions.Shared.ParameterDiscreteValue
        oFieldDefs = oRpt.DataDefinition.ParameterFields
        oFieldDef = oFieldDefs(sFieldName)
        oParamVals = oFieldDef.CurrentValues
        oParamVals.Clear()
        oDiscreteVal = New CrystalDecisions.Shared.ParameterDiscreteValue()
        Select Case iDataType
            Case ParamType.Int
                oDiscreteVal.Value = System.Convert.ToInt32(sVal)
            Case ParamType.Text
                oDiscreteVal.Value = sVal
        End Select
        oParamVals.Add(oDiscreteVal)
        oFieldDef.ApplyCurrentValues(oParamVals)
    End Sub
End Class
And here's how you would use them:
' Create an instance of the Crystal report
_rptCrystal = New CrystalDecisions.CrystalReports.Engine.ReportDocument()
_rptCrystal.Load(_oSBO.AddonPath + "\Reports\MyReport.rpt")
' Call SetCrystalLogin to see the logon information for all report tables
CrystalFunctions.SetCrystalLogin(sUser, sPassword, _oSBO.SboCompany.Server, _oSBO.SboCompany.CompanyDB, _rptCrystal)
' Set my report parameter value
CrystalFunctions.SetCrystalParams("MyParam", CrystalFunctions.ParamType.Int, 999, _rptCrystal)
' Print the report straight to the printer
_rptCrystal.PrintToPrinter(1, False, 0, 0)
The other way to approach this solution would be to base your Crystal report on a .NET dataset rather than a database connection. However, as you've already written your report, the code above is going to be simpler to implement.

Visual Studio 2005/2008 and Crystal Reports versions/upgrade questions.

I've tried posting this question on the MSDN forums and gotten no response.
I've downloaded and installed VS 2008 Beta 2.   The versions on the Crystal Reports files included are 10.5.0.1806
I'm currently using VS 2005, with the included Crystal Reports. The versions on those files are 10.2.0.xxxx. I've created an desktop app (in VB) which stores it's data in a database and uses the CR 10 runtime merge modules to generate a report.
I was considering upgrading the Crystal Reports version to XI. I would like to allow customers to modify my delivered report with their own licensed copy of CR XI. I am not providing any functionality within my app to create or modify the delivered .rpt or use it outside my application.
Questions:
Do I need to update the runtime files to CR XI to support rpt files modified with CR XI? Current runtime files are being delivered with the CR 10 merge module.
I see a Crystal Reports for Visual Studio upgrade to CR XI.
Can I update the merge modules to CR XI and still use the CR for VS2005 for development?
Does it make any sense to update CR for VS 2005? Or to get the full CR XI Developer edition? My usage of CR functionality is very limited.
Would there be any benefit to waiting for the release of VS 2008?   How does that change the scenario?
How does Crystal Reports for Visual Studio fit in with the Crystal Reports Lifecycle? It's not mentioned on Business Objects End of Life Dates page . Crystal 10 has a Patch EOL of 31-Dec-07.   Does this apply to CR for VS 2005? Where does 10.5 fit in?
My main concern is allowing customers with CR XI to change the format of my delivered .rpt to run with my app. Adding their company name, logo, etc.   My testing show a CR XI report still works with my current app. But, going forward, what should I deliver and what do I need to use to continue development?

To use Reports designed in XI, you need to use XI or higher runtime, running them in older versions may work, but you may encounter unforeseen issues doing so.
If you are to use VS2005 for development you need to use XI Release 2 (11.5) runtime.
If you are going to use VS2008 for development you need to use Crystal Reports 2008 with Service Pack 0.
The support end of life for versions of Crystal Reports bundled with Visual Studio are linked to what Microsoft's lifecycle for the product is. Generally if there is a workaround for the issue that is simple enough, there will not be a patch created.
The changes you are expecting the customer to do can be accomplished with our RAS SDK which is available without using enterprise starting with Crystal Reports XIR2 SP2.

How to change Crystal Reports XI database name at run time from ASP code using ADO

Dear All,
I need advises regarding to my problem below
I have two database in same SQL 2005 SERVER for TEST01 and LIVE01 Environtment, and I've created more than 100 reports with Crystal Reports 11 and call it from ASP classic page.
The problem is how can I change a database from TEST01 to LIVE01 at the run time from ASP code as I already using TEST01 database on Crystal Reports and I do not want to set a new database location inside crystal for each reports
Thanks and wait for your reply soon.
Below is my code, which has no effect to crystal reports although I've change the database from TEST01 to LIVE01:
<%
Dim oADOConnection, oRptTable, oADORecordset, sql
Dim struser, strpwd, strdriver, dblocation, dbname, strConnect
struser = "sa"
strpwd = ""
strdriver = "{SQL SERVER}"
dblocation = "SQL200501"
dbname = "LIVE01"    ' Changed from TEST01 to LIVE01
strConnect = "User Id=" & strUser & ";"
strConnect = strConnect & "PWD=" & strPwd & ";"
strConnect = strConnect & "DRIVER=" & StrDriver & ";"
strConnect = strConnect & "SERVER=" & DBLocation & ";"
strConnect = strConnect & "DATABASE=" & dbName
sql="Select * from Employee"
Set session("oApp") = Server.CreateObject("CrystalRuntime.Application.11")
Set session("oRpt") = session("oApp").OpenReport("C:\REPORTS\RPT01.RPT", 1) 'USING TEST01 DATABASE
session("oRpt").MorePrintEngineErrorMessages = False
session("oRpt").EnableParameterPrompting = False
session("oRpt").DiscardSavedData
Set oADOConnection = Server.CreateObject("ADODB.Connection")
oADOConnection.Open (strConnect)
Set oADORecordset = Server.CreateObject("ADODB.Recordset")
Set oRptTable = session("oRpt").Database.Tables.Item(1)
oRptTable.SetDataSource oADORecordset, 3
session("oRpt").SQLQueryString = CStr(sql)
session("oRpt").ReadRecords
%>

Did you ever find a solution to this problem? I have the same problem when moving reports from development to Test to Production environments. If the DBName is not the same the report ignores the name provided at runtime.

How to change crystal report data field at runtime ?

Hello everyone,
I have a Crystal Report file ,which i am using to generate report for my windows form project .
In that report i have a filed called as Quantity which data type is set as decimal, the requirement is like that the number of value those comes after decimal point that should be set according to the value which is given by the user at the run time .
For eg: If user gives 1 at the run time then the report Qty field value set one value after decimal point. Like 12.1
if user gives 2 then Qty field the value is 12.22 like tat but user can give from zero to any number.. and if it is zero it should not show decimal
Note: The main idea hear is how to change the filed in Crystal Report decimal point value by using code(or we say writing code we need to set manually as user input it will change)
Can any body help me how to solve this issue .
S.K Nayak

I think you could probably make the field you see a formula field and take a parameter as the number of decimal places.
totext converts a number to a string.
totext({decimalField}, 2)
That's 2 decimal places.
You could probably substitute a {parameter} for that 2.
If not then you could substitute an entire formula.
To explore formulas:
foreach (FormulaFieldDefinition f in rpt.DataDefinition.FormulaFields)
MessageBox.Show(f.Name);
// f.Text = your new formula
Where rpt is an instantiated report.
Or add another string field which you display in the column and do the calculation with the original decimal.
Hope that helps.

Crystal Report Connectivity to Function module

Hi,
I have a crystal report which is connected to a Function module in ECC(dev). After the function module moved to Quality I could repoint the crystal database to Quality. Later, some changes were made in the function module fields (eg: change in field length etc) by the field names were kept same. now when i try to repoint the database it says field not found and the report canvas becomes blank. but I can see the fields in the field explorer.
is there a way to correct the error?
Thanks, Arka

Hi Arka,
When you open the report then log into the DB and then click on Database, Verify Database. This should update the database info and changes in the report. CR keeps track of the DB it's connecting to so if you make s changes you must Verify the database to update the info in the RPT file also. Be sure to save the report.

Crystal Report connecting Multple ECC systems

Hi,
I am working on crystal where I compare the data between to two diffrent databases(ECC tables). I am using SAP Table, function mudule option to create connection.
I have built a main report against ECC system A and imported a sub report built on ECC system B. Now I see that connection in my main report is overwrting the connection in the sub report. If I change the connection in the subreport with set data source location it changes the connection of both sub report and main report. After I deploy this report to infoview, in cmc I see only one database connection.
Is this a bug or can we have only one connection to ECC system per one crystal report even if it has sub reports?
Thanks

Yes that happens automatically, I just checked the same logic with universes built against oracle data source, I could see two coonections in the CMC. Its like its there is this issue when I am connecting to sap tables directly

LCM can not map Crystal Report connection properly

Hi,
We are using LCM to transport Crystal Report files from Devlopment server to Quality. The transports are successful, we can also see that connections (to source) also has been changed properly.
These Crystal Reports have 3 parameters. Our requirement is to refresh the report with two parameters having no value (it will produce record for all values). And it works fine in our development system.
But it is not refreshing and scheduling fails also. Error message is 'Information is needed before this report can be processed'. But if I put some value to all 3 parameters, then it refreshes properly.
But I need the report to be refreshed with one parameter vale (other will remain empty) as it works in deveopment system.
Can you please help me out?
Regards,
Avijit

Hello Dutta,
if you keep the parameters blank why not removing them ?
But thats rights, this should be a setting in your CR instead something with LCM.

Hi,
To be able to report off an SAP data source in Crystal Reports, request the SAP Administrator to set the appropriate authorizations for the user.
For a list of authorizations that are necessary for each type of SAP connection, consult the document:
BusinessObjects XI Integration for SAP Installation Guide
In the "Authorizations" chapter, there is a description of each authorizations needed for each type of connection and actions.
( The document is attached to this SAP Knowledge Base Article in the attachment section )
In addition to the authorizations specified in the SAP Integration Kit Installation Guide, the following authorizations are required:
For Authorization object: S_RFC with Field name: RFC_Name. According to the installation guide the values should be: SYST, /CRYSTAL/OPENSQL
Additionally you will need the value: SUSR as well.
For Authorization object: ZSEGREPORT with field name: ACTVT. According to the installation guide the value is: 02 (Change)
Additionally you will need the value: 01 (Create or generate) as well.
Thank you.

Change crystal report data source dynamically failed with multi tables report

hello all
i have many reports created by someone else on his own machine using same database file i use
my application use Visual studio 2013 win form with crystal report pack 9
i use rpt files provided to me
connect database use OLEDB
to show form i use below code
SQLstr = " select what ever from table "                      ' defined as Public
reportName = rpt file path & report name
showReport()
public sub showReport()
reportTable.clear()                                                       ' defined as Public
DBAdapter = new oleDpdataAdapter(SQLstr,DBconnection)
DBAdapter.fill(reportTable)
dim rptDoc as new Crystaldesicin.crystalreports.Engine.ReportDocument
rptDoc.load(reportName)
rptDoc.setdatasource(reportTable)
formRpt.RptViewer.reportsource = rptDoc
formRpt.showdialog()
now
when i use one table report with (select from one table) >>>>> works perfectly
but when i use report retrieve data from 2 tables and group   data like using
SQLstr = " select 'table'.'coulumn', 'table2'.'column' ....... etc
from 'table1'
INNER JOIN 'table2' ON 'table'.'coulumn' = 'table2'.'column'
it's not working and formrpt shown but asking for database login
I noted that in database login window : server name refer to ORIGINAL DATABASE USED BY Report Creator not to my local database
================================================
i tried to set
rptDoc.datasourceconnection.item(0).setconnection("","databse file path and name", False)
rptDoc.datasourceconnection.item(0).setlogin("admin","")
but the same
using dataset instead of reportTable the same error
================================================
what i missed in this type of reports?
( apologize about long take and poor English )

There is a specific set of authorizations that you need to provide to your SAP user to be able to create CR reports against SAP data source. Check in the "SAP BusinessObjects Enterprise Integration for SAP Solutions Installation and Administration Guide" chapter 13 called "Authorization".

Please help me, it's urgent.
Thanks,

Ingo,
I've downloaded V 10 and installed it. But it does not display 'SAP' in 'other datasources', when i start creating report from crystal reports using other datasources.
When i downloaded V 8.5 addon, i 've installed crystal report v 8.5 and then installed v 8.5 AddOn. This atleast shows SAP menu in it. but when i start creating report from it, it displays same missing function module problem.
So in both version, I'm having problem. In V 10 SAP menu is not appearing and in V 8.5 SAP menu appears but missin function module problem. Is there any Addon for V 10.
Please guide me.
Thanks,
Salahuddin.
