Data Source CE in Visual Composer

Hello Experts,
we are running on CE 7.2.
I wanted to read BPM task details into a custom application or generate a report of who has claimed the task,currently being processed by whom and the history of this information relating to every task in uwl.
I know that CE 7.3 offers BPM API's using which thiscan be accomplished.
However I have also read that Visual Composer can provide this solution.
I have the following queries:
1)what data source should be selectedif i choose to go with vc
jdbc BI template? or BI....we do not have a Bw system in our landscape and our datasource is portal DB.
2)Does that mean BI usage type will have to be installed alongwith BI jdbc connector..
3)what would be a more feasible solution ...upgrading to 7.3 or installing the BI component. ( we need to perform only reporting activity as to with whom the task is currently pending and ho had processed it in the past)

Hello Jun,
Thanks for the reply, however i still have some queries.
1)I could not find the standard BPM datasource in the dropdown of select providers.
I therefore selected BI Data sources even though we do not have a BW system .
2)I tried selecting standard BPM tables to fetch the data.
viz; BPM_MYTASKS_DS..I want to know if there is any standard table which stores information about who had and who is currently proceesing tasks , if yes can you please provide the name of table or how can i make it available in visual composer's "search for table" field while creating new model.
3)we are also trying to upgrade to 7.3
Now BPM & CE are on same instance.
Can only BPM 7.2 be upgraded to BPM 7.3 instead of entire CE portal from 7.2 to 7.3?
4)Also i read somewhere that it would be an entire upgrade to netweaver 7.3 and in usage type we will have to select the usage type of what we want to upgrade like CAF to 7.3, BPM to 7.3 and so and and so forth. Is this right?
5)Can also you please let me know in which situation we should use visual composer and when BPM api is suitable?
Thanks

Data Service System In Visual Composer 7.1

Hello,Experts:
Recently ,i am focusing on the mirgration function of SAP NetWeaver,and visual composer is among them .
In netweaver 2004s enterpise portal ,i have done the system connection between Enterpise Portal and ECC and BW ,and the system alias can be accessed in visual composer .Both the bapi and infocube can be got by the system alias .The Visual Composer Application based on the backend data service is ok .
However ,i have registry the ecc system in CE Portal and its version is SAP Composte Environment SP5 .I can check out the system registry is ok . However ,when i open the Visual Composer on the CE Portal ,i couldnt find the system alias that i have registried .It is blank .Plus,we havent install SLD on the CE Java Server ,and solution manager is put forward to take the place of sld .
Can anybody help me out ? The problem has any relationship with the Enterpise Service Repository ?
Thanks for your help in advance .

Hi Eleanor,
first of all if you want to use SAP BW in Visual Composer for CE then you have to install Enhancement Package 1. SAP BW resp. queries, planning functions and so on is only supported with VC 7.11 (EhP1 for CE). I also recommend you to set up the SLD in your CE system resp. that it works as a "slave SLD" when you have an existing SLD in your landscape. There are wizards available in the NetWeaver Administrator.
Go to http://<host>:<port>/nwa to login into NetWeaver Administrator.
Navigate to Configuraton --> Scenario --> Configuration Wizard and choose the Initial setup of functional unit SLD.
If you want to have access to BAPIs there are two ways to access the system. You can define a portal system object to access the ECC or you can define in NWA a RFC connection to access ECC.

Hi,Govindu
I have read that message already .Thanks for ur help .
However ,i find that there's no VC-Role in CE SP5,and the permission add-in didnt work .Besides ,when i deploy VC component on the EP 6.0 ,i can find these iviews or models at the directory of content administrator->visual composer ,while in the new version ,i havent find the configuration path on the Visual Composer Client,and when i deploy the VC Applications ,it is deployed in the path of webdynpro content management .
and my question is still up in the air .

How export data in Excel From Visual Composer

Hay everybody,
I would like to export my data result from Visual Composer to Excel. I've tried with an export data buton, but the exported file has a very bad format in Excel. I've tried an hyperlink buton which contain the Reptname data of the query too, but I can't keep my filters. This second solution can be nice for the format. If anyone knows how I can keep my filters, I would be fine.
Thanks

I did not get solution by using BW 3.5 , can we export data to Excel ? I am refering

Update master data in BW with Visual Composer

Hi guys.
I have an attribute of an info object that I need to give the users access to update.
I would like to do it with visual composer.
I would like the user to see all rows in a table kind of view and the user will update only the rows that need to be changed and than he/she will click on a button that will update the master data table in BW.
I believe that I'll need to use a BAPI or a RFC for that? Does anyone know any good predefined ones for that?
Thanks
Shlomi

That's not really true. In VC you have access to all remote enabled functions. We have created specific functions to update attributes.
We are using it to allow our users to update their own master data instead of bugging the BI team.
Here is an example of our code.
Before I paste this in, you need to know a couple things.
1. You can only update one record at a time (with my code)
2. You have to pass back in the entire record, even if you are only changing one attribute of many.
3. It automatically does the attribute change run, so you do not need to to it.
This is a simple infoobject with a few attributes.
First we created a Get function (which collects the data and shows it to the user.
Then we gave them a edit button on the table that goes to a pop up.
The user selects the record to change, then hits the edit button.
When the popup comes up the data is shown in a form, with a save and cancel button, fields that you do not wish users to see or change, hide them, but they all most be present on the form.
The when the user hits save, it send it to the below function. The name of the infoobject is ZCAT_SUB.
FUNCTION zcat_update_subparty2.
""Local Interface:

Access data from SqlServer through Visual Composer.....?

Hi Gurus,
I could able to connect SqlServer database from Visual Composer. After that, how can I access table data from sqlserver database?
Thanks in advance....
Ravindra.

Ravindra,
Here is the work around to do this. You will need to create a New System. In the Portal go to System Administration -> System Configuration -> System Landscape. Create a New System from PAR. Select com.sap.portal.systems.BIUDI, click Next. Select SAP_BI_JDBC and enter all the information that you would normally use to connect to a SQL DB using JDBC. You can then in the VC run SQL against the tables. Open VC, and Navigate to the iView level and go to the toolbar and Select BI -> SQL Editor. It is pretty self-explanatory from there.

Peter

How to use BEx or Visual Composer to visualize 3rd party tool data?

Hello,
could you give me ideas how to visualize non-SAP warehouse data with BEx or Visual Composer?
I know that one option is virtual provider with connection to external DW. I do not want to load data into BW.
Is there any other way? If yes, how it can be done?
Thanks,

3.3 Connectivity and Interoperability
This section briefly describes:
The means of connecting Visual Composer Storyboard to the required back-end systems
The technology environments to which models composed in Storyboard can be deployed
Connectivity with Back-End Systems
Visual Composer provides tools that let you connect via the portal to back-end applications defined in the portal system landscape. This connection enables you to import into your model the relevant function modules on which you want to base your iViews. The imported function modules are referred to as data services.
Normally, you can connect to any installation of a back-end application to import a data service, and then deploy the content to any portal that enables access to an instance of the same back-end application. However, if the customer installation of the back-end application includes customized function modules, you will need to import the data services in the customer environment, in order to retrieve the customized functions.
Most connections to back-end systems are accomplished using the SAP and JDBC connectors deployed automatically as part of the connector framework installed with the portal. The SAP connector provides access to R/3 and BW systems, while the JDBC connector provides access to a wide range of databases, including Microsoft SQL, Oracle, DB2 and others.
BI connectors, installed separately in the portal, can be used to access a range of different data, including multidimensional cubes, relational tables and queries. Connectivity is based on defining a system in the portal landscape. You may define systems for the following connections:
BI XMLA
BI ODBO
BI JDBC
BI SAP Query
In addition, you can configure the BW system, installed automatically with the SAP connector, for accessing predefined queries.
The following table describes the systems from which Visual Composer can import data, and the connectors that are required. The Connector (second column) indicates the name of the connector used to install the system in the portal.

Date Format from webservice to Visual Composer

Hi all,
i'm using a webservice in a visual composer.
My webservices gives me some fields, three of this fields are date type in the following format:
YYYY-MM-DD (eg. 27.05.2008), this is soap message of the webservice.
when i insert those date in a table, Visual Composer changes the format as following:
MM.DD.YYYY (eg. 05.03.2010) where Visual Composer consider 27 like 12 months12months3 months, 3 is march, and its increase year (2010) becouse of 24 (12+12) months.
Portal language setting is English, and i cannot change it.
There is someone that can help me??
Thanks!!!!

Hi,
Then the formate you can change in Visual composer to YYYY.MM.DD using Date fromulae .
Plz check in the Formate tab of the Date field and chenge it to respective Formate you want.

Writing to a data source in JavaFX composer

Hi,
I'm creating a JavaFX app that needs to write to a JavaFX storage device. I'm using the Storage Data Source in the JavaFX composer with NetBeans 6.9. I know how to read from the data storage device, but how do I write to it? I have the device currently set as a JSON device, but I can change that.
Are the docs on the storage devices in JavaFX composer? I read the NetBeans wiki on data storage.
Thanks,
Vance

Hi,
there is no specific support for writing to a Storage data source. Please use javafx.io.Storage API for writing to Storage devices.

Visual Composer - filter data service results

Hi,
I'm using a data service in the Visual Composer which returns serveral result tuples. I want to display just the first tuple in a form view so I need to filter the result. How does it work? I tried different operators (especially filter) but without success. Any ideas?
Kevin

Hi Micha,
you are right, I had solved the problem like that. I was struggling with the columns that were (not) displayed after applying the filter. My solution is to include every column necessary in the filter values.
Best regards, Kevin

Thanks & regards

Hello Amrita,
The exception complains that it - Cannot create DataSource "AmritaKediaDS"
The Data Source may not be defined correctly - the userid,
password etc. or the database server name, port - one of them
is not correct probably.
Also check if you have included the following jar files for the driver:
<li>spy.jar
<li>mssqlserver.jar
<li>sqlserver.jar
<li>msutil.jar
<li>base.jar
<li>mssdup.jar
<li>msbase.jar
The driver class is
com.microsoft.jdbc.sqlserver.SQLServerDriver
and the URL is jdbc:microsoft:sqlserver://<yourserver>:1433
I got this list from one of my working SQL Server drivers.
Hope this helps.

Visual Composer 7.0: system (data source) does not appear

Hi...
There is a problem: system (data source) does not appear in Visual Composer 7.0
1. There is a connector MDM. It is made by PCD. It has been tested. The test is ok.
2. However, as the data source in Visual Composer a connector MDM does not appear.
3. This problem affects all types of connectors, but the Web Service Connector. Connector Web Service is always there.
What the .....?
P.S. The role of the creator of the connector is the same user of Visual Composer
Thanks...

2 data sources in same chart in Visual Composer

Hoping you can answer a question for me.
Do you know if there is a way in Visual Composer to combine the output of 2 data sources into the same chart or table?
Here is an example of what I am after.
Inside BW, we currently have sales history for the company (i.e. monthly sales numbers). We can use a BW query as data source for this data.
Now we have found some interesting web services that provide 'market' type data,( i.e. some economic indicator) that we'd like to corrolate to these sales. We'd like to also chart the monthly value of this external indicator on same chart. I can use an external web service as a data source for this data. Howveer, VC seems to only allow me to send the output of this service to a separate chart/table. This is not ideal. I'd rather be able to incorprate in same chart.
If this is not possble, can Web Application designer consume web services? If so, I'd be fine with doing whole application with this tool.

Hi Brad,
Technically it is possible to combine to data souces using COMBINE, UNION operators. So the resulting table contains columns of two data souces.
You can use this resluting table to create a chart.
I have not checked this uisng web services. But it should be possible.
Thanks,
Venkata
