Iframe used to point to a URL with dynamic parameters??

Hi guys,
I am new to web dynpro java and having my first webdynpro project. Just wondering how to acquire the host name, port number and error message info. dynamically in order to form the following URL format. The iframe is directed to this following URL address.
http://<%host name%>:<%port number%>/portal/ErrorPage.all?MSGID=<%=SYMSGID%>&NO=<%=SYMSGNO%>&PROG=<%=SYREPID%>
I need to replace the <%...%> part with the dynamic content. Any one could provide me with some ideas? What java classes I should use? Thanks very much.

Hi Libai
Please refer to below docuement for getting host and port number in web dynpro for Java application.

ABAP WebDynpro app calling Transaction iview with Dynamic Parameters..?

Good day!
I need to code a call to a transaction (with dynamic parameters) from an Abap WD application. It appears that to achieve this, the app needs to call a new portal transaction iview, passing the parameters in the call..?
This should ideally be via a Sapgui for Windows, but Html also an option (does it matter with regards to the method used?).
Kindly assist with advise/instructions, idealy with sample code extract to illustrate (new to Abap WD)...
Kind regards

Use BUSINESS_PARAMETERS to pass the data
Abhi

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.

Running a SQL Stored Procedure from Power Query with Dynamic Parameters

Hi,
I want to execute a stored procedure from Power Query with dynamic parameters.
In normal process, query will look like below in Power Query. Here the value 'Dileep' is passed as a parameter value to SP.
    Source = Sql.Database("ABC-PC", "SAMPLEDB", [Query="EXEC DBO.spGetData 'Dileep'"]
Now I want to pass the value dynamically taking from excel sheet. I can get the required excel cell value in a variable but unable to pass it to query.
    Name_Parameter = Excel.CurrentWorkbook(){[Name="Table3"]}[Content],
    Name_Value = Name_Parameter{0}[Value],
I have tried like below but it is not working.
Source = Sql.Database("ABC-PC", "SAMPLEDB", [Query="EXEC DBO.spGetData Name_Value"]
Can anyone please help me with this issue.
Thanks
Dileep

Hi,
I got it. Below is the correct syntax.
Source = Sql.Database("ABC-PC", "SAMPLEDB", [Query="EXEC DBO.spGetData '" & Name_Value & "'"]

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

ABAP WebDynpro: Call a URL with POST-parameters?

Hi all,
I want to call a URL from an ABAP WD method with additional data. I know that this is simply possible via the Window Manager, passing a URL. Adding additional parameters inside the URL is of course also possible using "&" and "?" separators.
Is it somehow possible to call such a URL out of WebDynpro with additional POST data (e.g. an XML datastream)?
Best regards.
Alexander

Hi Alex.,
As u said that u know how to call URL and pass parameters using window manager., and i am not sure about XML data stream.!!
I can advise u to post ur thread here: [Web Dynpro ABAP Forum|Web Dynpro ABAP;
U will get some useful inputs..
Thanks & Regards

Web service URL with multiple parameters

Hi all,
I'm trying to make use of a web service that takes multiple parameters without the use of a proxy (we're using NW 7/7.1 and proxies aren't supported - i.e. i'm getting the same thing as described here: Proxy object to consume web service)
So instead I'm trying to follow a method similar to what is done [here|http://sample-code-abap.blogspot.com/2009/05/simple-code-consume-web-service-using.html]
When I put the web service url into a browser and click on the operation it comes up with
http://portLocation/company/webservice.asmx?op=operation
and comes up with the sample SOAP request and response as normal.
Now with most web services with one parameter, the url translates to something like: http://www.webservicex.net/globalweather.asmx/GetCitiesByCountry?CountryName=australia
Which works fine.
However, the web service i'm using has 4 parameters and when I try and translate my url to be like this (http://portLocation/Company/WebService.asmx/Operation?parameter1=XX&parameter2=XX&parameter3=XX&parameter4=XX) I get, "The page cannot be displayed"
Can anyone suggest a way that I might be able to get around this or what I'm doing wrong.
Thanks in advance.

Hi,
are you sure that your Operation is valid? So for example in your [example|http://www.webservicex.net/globalweather.asmx] there are just two operations: [GetCitiesByCountry|http://www.webservicex.net/globalweather.asmx/GetCitiesByCountry] and [GetWeather|http://www.webservicex.net/globalweather.asmx/GetWeather]. You are right about passing multiple parameters. You need to put ? after valid URL and then pairs <name>=<value> separated by &. Don't forget that you need to encode <name> and <value> to avoid problems.
Cheers

Calling SAP Trx with dynamic parameters using EP6SP2

Hi
I would like to call an SAP transaction from EP6 and pass parameters (one is variable) to the initial screen, process this screen so that the user is dropped into next screen ready to work.
I would like to pass the screen field's value, which is variable, as a URL parameter.
eg. http://<ep6 server>/...?p_id=xyz
How can I do this?
Thanks
Doug

Hi Doug,
You can write a custom Java iView, calculate the variable param there and use URLGenerator to get the URL for the SAP transaction. Then just display it in an IsolatedHTMLContainer in the iView.

Patrick.

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.

Calling APEX form with dynamic parameters from Oracle Apps 11.5.8

I have successfully managed to setup access to APEX forms from Oracle Apps 11.5.8 menus utilising Form Functions passing a number of hardcoded parameter values as outlined in the document, http://www.oracle.com/technology/products/database/application_express/pdf/Extend_Oracle_Applications_11i.pdf.
I am now trying to ZOOM from an Oracle Form passing values of form items (dynamic parameters) to an APEX form. I have so far not been able to do this.
I've also tried using;
web.show_document('http://derep.obup.co.uk:4657/pls/apex/f?p=100:1::::::p1_cust_account_id:'||name_in('ast_cu_act.account_id')||':', '_TOP');
but this prompts for a username/password again as this bypasses the APEX Launch process that is defined in my Form Function.
Is this possible in the parameters section of Form Functions? or elsewhere.

Naeem

Hi Daan
We do havea couple of customers doing this, they have taken two approaches:
1. Install XMLP on a separate server entirely - kick off conc request to extract data and then use Java Messaging Service (JMS) to push the resulting XML to the external server where they are using AQ to set up jobs for the XMLP server to work through, generating and delivering the final documents.
2. Set XMLP up as a virtual printer - here the conc request again generates XML but this time the result is directed to a virtual printer namely XMLP. There is a perl or similar wrapper that gets called as the printer and accepts the data, template, output format and delivery destination as parameters.
Apologies for the 10,000 feet overview, hope it helps. Tim

SSRS 2008 R2 - Using Action to call a report with MultiValue Parameters

I have a report uses project names as parameter(Multi value) and display some data. I want to call this report from some other report on a click (drill down). This report has a program row where it aggregates the data, underneath Programs, I have
list of projects(group). When I use Action on the individual projects, it takes me to the appropriate project ( I used
Fields!ProjectName.Value). However, when user clicks on the program, it should pass the group of projects within that program to the called report. With expression, Fields!ProjectName.Value, it only select one random project (may be first/last from
the query) and display records. I tried Join(Fields!ProjectName.Value, ",") and Fields!ProjectName.Value(0) but now it doesn't select a sengle project. Can someone help please?

URL with Dynamic Content

Hi WD Gurus,
after executing a BAPI I get back a filename and an URL (generally it is an excel file)
The url is something like this:
"HTTP://srm.customerX.com:8000/sap/ebp/docserver/110/ScreenTemplateChanges.xls?attkget&KpId=26DE385E3F454BBA7B7244280B12C7&KpClass=BBP_L_DOC"
I want to expose the filename and the URL as its link.
At first it seems pretty straightforward... but I already tried LinkToURL, LinkToAction and FileDownload
but it seems that you have to have your excel file "pre-loaded" in your WD app, but I can't have that
because I get this the URL when the BAPI is executed....
Can somebody help me out? I am using Web AS 6.40 SP13
thanks,
Kentaro

Hi Maksim and Satyajit,
the problem is that I am getting a web resource not found message indicating that it can't find the excel file in the web AS server. Actually the file resides in the SRM server that is in a different url/machine.
I will get the detailed message as soon as I get in the office.
regards,
Kentaro

[SOLVED]PKGBUILD - source=() and urls with get parameters

I tryed to compile pyflakes from AUR yesterday, and it had a `source=(http://divmod.org/trac/attachment/wiki/SoftwareReleases/$pkgname-$pkgver.tar.gz?format=raw LICENSE)` the problem is that makepkg checks for "$pkgname-$pkgver.tar.gz?format=raw" and the file name is "$pkgname-$pkgver.tar.gz", any fix for that? - I just removed "?format=raw" and it worked, but the author must had a reason for that parameter

Ho can I schedule a WEBI report with dynamic parameters???

Hello again!!
Here i am with another detail about scheduling, the thing this time is that ia need to schedule a report with one parameter every week but with a different value for the parameter every week.
This is i need this week to run the report SALES BY STORE filtered by week with this value 2011 - 45 (yyyy - num ofweek) but the next week the value for the same parameter must be 2011 - 46
is it possible??? i mean is possible to schedule a report with different value for the parameter each time that it runs???
I know that i can schedule a report with different values for a parameter to send it to severals users whith different data but the values for the parameter are the same every time that it runs and i dont need that.
Any help or clue will be very appreciated

Hi Elio,
Do you have access to modify your universe?
Then you should try Dave Rathbun's idea. Here is the link:
http://www.dagira.com/2008/07/21/using-a-magic-date-value-in-prompts/
Note that you'll have to adapt it to what you need, in this case to the week number.
For example if you are using Sybase syntax you'd get 2011 - 46 with:
convert(varchar, year(getdate()))+' - '+convert(varchar, datepart(wk,getdate()))
So you'll new object in Universe would look like :
your_table.week = case when @prompt('Enter week','C',,mono,free) = 'This week' then convert(varchar, year(getdate()))+' - '+convert(varchar, datepart(wk,getdate())) else @prompt('Enter week','C',,mono,free) end
Adapt it to the syntax of the database you use. Then after creating this object in your universe you'll have to go back to your report and Edit the query and use this object in the filter area instead of a normal prompt.
When you have to schedule the report leave the prompt with the parameter 'This week'
Hope this helps
Regards
Erika
