Webservice system error in visual composer

Hi,
I am facing a problem with respect to using a webservice in my Visual Composer application. I have defined the webservice system with a WSDL url in the visual administrator giving the required login credentials. I am trying to access the entire function group that contains some BAPI's. When i access this system in my Visual Composer, i can see the entire list of BAPI's that it contains converted as web services. But, when i try to drag any of the BAPI's i get the following error
Failed to fetch Metadata.
Portal Request failed due to: Operation
not found.
Now when i put the same WSDL in my browser, the list of services can be clearly seen. Any solutions to this?

Hi Mario,
The problem is solved now. We cannot drag a webservice system directly into a layer in VC but first needs to be dragged on to your story board and from there into the desired layer!!! I am not sure why this occurs but my colleague here found this out. But now i get the error Portal Request Failed (Could not execute web service operation). i checked the following link
https://www.sdn.sap.com/irj/sdn/wiki?path=/display/vc/portalRequestFailed&
The BAPI that iam testing as a webservice has one fo the input in the form of a object, to be specifc a HROBJECT whose structure contains 3 components. Can this be the cause of the problem?
Thanks and Regards,
Arun EV

Runtime error in Visual Composer

I'm develping a Composite View in Visual Composer using BAPIs. I'm using BAPIs just because my SLD isn't ready to publish the enterprise services from ECC and SCM/APO. The main objective is learn how to use VC to create applications consuming data from BAPIs, Web Services, BI Query etc...
I developed a simple application using the bapi: BAPI_LOCSVAPS_GETLIST2 from sap APO.
Inputs ports:
LOCATION_SELECTION - TABLE
Input: LOGICAL_SYSTEM and MAX_NUMBER_OF_LOCATIONS - signal
The problem is the following: when only the out port ouput is used, there isn't any problem, and is possible to compile and deploy the Composite View and the output (NUMBER OF LOCATIONS FOUND) is correct.
But if I try to select some TABLE out port like LOCATION_TEXT, an error occurs in runtime (compile and deploy without problems): Connection Error: contact your system administrator: HTTP request error.
I tested the RFC Connections and also, tested the BAPI using the Test Data Service and all the tests were ok and that's why I don't know what is wrong. In design time there isn't any problem, instead in runtime the error mentioned above occurs.
EHP1 SP1 for SAP Netweaver 7.1
IE Version 7.0.6001.18000
Data Source :ECC and SAP APO u2013 In VC is used BAPIs, configured via RFC Destination
Thanks...

Hi,
I think "Implementing a GP Interface" makes no sense in this case. Take a look at <a href="https://www.sdn.sap.com/irj/sdn/wiki?path=/display/vc/limitationsofWeb+Dynpro&">VC: Limitations of Web Dynpro</a>.
It seems that Web Dynpro in VC is not supporting all kinds of services and functions.

Error in visual composer

HI Friends,
I downloaded "SAP NetWeaver 2004 Java Trial Version" from sdn and installed on my laptop. In "Administration" user there is "pcd:portal_content/com.sap.gm.cnt/core/VCRole" role assigned to user. When accessing http://localhost:50200/vc, I am getting error 404 not found, The requested resource does not exist.
Can anyone please help me.

Hello,
do you get the login screen or only the blank page?
I've searched the SDN for "Visual composer blank page" and found those 3 things:
1. SAPNote: 954467
+In Visual Administrator -> Services -> "HTTP Provider" -> Properties . Add the following to property Mime: {.htc,text/x-component}
Close all open browsers and clean the client cache. Try to reload Visual Composer. If it still does not work, restart J2EE.+
2. This thread -->
Hope it helps.

Error in Visual Composer - winsvc.exe

Hello. I have installed Visual Composer 6 and Service Pack 2. However when I connect to my portal(6.4 stack 4) I get the following error:
Error winsvc.exe?get=1846140
It is installed on a windows 2000 server and IIS version 5.
Please help.
Pete

Hi Pete,
It seems that you haven't install one of the Visual Composer prerequisites - SVG Viewer 3.0, it should be installed on the machine you use to connect to the Visual Composer. you can find it in the Adobe site.

Error deploying Visual composer Application

Hi,
I have developed a simple VC application which compiles ok.
however when I select deploy I get the message:
Error in compiling Flex application: Warning: Cannot convert string "-monotype-arial-regular-r-normal--*-140-*-*-p-*-iso8859-1" to type FontStruct
Error 1103: There is no property with the name 'ROADMAP'.

Has anyone come across this before and knows what the problem is?
It seems to be complaining about a ROADMAP property but I don't know what this is.
Many thanks
David

Hi David,
can you post your model here? So that we can check it on our systems?
You can also make a copy of your model as backup then delete different parts and find the elements during try and error procedure.

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 .
Eleanor

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 .

and my question is still up in the air .

Solution for Visual composer error: 32k span and 64k byte limit

Dear friends,
I am getting the error in visual composer 32k span and 64k byte limit since last half year,
some time error will get resolved by adding layer in to model OR adding some table and form to model OR reduce the animation effect OR even by doing tab strip view for layer model, doing nested ivew.
but this solution not usefull for every time.
what should we do for this error(32k span and 64k byte limit),
is it solved by updating EP version or by EP java stack or any other updates which will solve the This VC error.
64k error i am getting is:
+Error in compiling Flex application: Error: A function in the code exceeds the 64K byte limit (actual size = '65570'). Since the problem occurs in the compiler-generated deferred instantiation code, please refactor/componentize portions of this document.

Failed to compile AADCDM.mxml+
hope to get answer form you,
Thanks and Regards,
Dushyant.

Hi,
I think it's better to post this question into the Visual Composer forum. Anyway, the 32k/64k bug is solved with the flex2 server which is already released.
Also have a look into the [Wiki page|https://wiki.sdn.sap.com/wiki/display/VC/64Kbytelimit].
Hope that helps!
