trying to access R/3 system in VC , getting error

Former Member

Hi all,

my project requires me to get materials from r/3 and insert into my application.

i have to create a model in VC which does so. I have identified BAPI_MATERIAL_GETLIST and BAPI_MATERIAL_GETDETAIL which would do it for me.

now i know to access these BAPI's i have to define a system in EP for r/3 which i have done.

Now when in VC , i say <b>Find Data</b> Service , and select the r/3 system that i configured , it says

<b>Falied to Connect to backend system. Check your system definition and user privileges.</b>

<b>In EP</b> this is how i have defined my system.

created a system of type "SAP system using a dedicated Application Server"

gave the following Properties.

A) Connector

1)Application host : my host

2)SAP Clinet : 000

2) SAP System Id : RTD

3) SAP System Number : 00

4) Server Port : 3200

5) System Type : SAP_R3

B) User Management

1) Authentication Ticket Type : SAP Logon Ticket

2) Logon Method : UIDPW

3) User Mapping Type : admin,user

then gave System alias to my system.

Defined an user mapping within j2ee_admin user (Last tab which says User Mapping For system Access), choose my system there and gave r/3 user id and pwd.

Now in EP too i guess i have some connection problem .. I mean in one test it succeds and other it fails.

<b>Succeds in this test</b> , which means my connection parameters are correct :

<b>System administration->Support-> SAP Application->SAP Transaction->i gave my system Alias->Transaction code as SU01->SAP GUI type as SAP GUI for windows</b>. It displays r/3 window where i was able to create a new user.

<b>Fails in this test</b>.

In system Administration -> system Confguration, i select my object and Choose Display as "Connection Tests" and choose <b>Connection Test for connector</b> but it fails saying

<b>Connection failed. Make sure user mapping is set correctly and all connection properties are correct.</b>

<b>so am really confused as to where i am going wrong.

How do i define a system for R/3 so that i can access its BAPI's in VC.</b>

Dear Rohit Sharma or anybody else,

first please add me scroe.

Maybe all your configuration is OK

but please login /useradmin or User Administrator

search the user you want to login

click Modify

Tab: User Mapping for System Access

select the system

input user ID and password

and test again, you can make it

thanks ajay but it din help much , as it doesnt speak about connecting to r/3 using VC.

<b>dont know why sap did such a boasting</b> that even a bussiness analyst can develop applications and what not . Who is going to do configuration for him ? they should have given a way in VC where i define my R/3 system connection parameters which should have internally created a system in EP. huh , neways i have to find a way out of this ....

I think your problem is you are connecting to client 000. You need to connect to the R3 client you're using and the user needs access to the BAPIs in the R3 system. My guess is that the j2ee_admin doesn't have the access in the ABAP system to these BAPIs as well, so fix those 2 things and you should be good.

Hello Mr.Prakash,

thanks for your reply.

the client 000 is my r/3 client number(on another machine) to which i am connecting , and in the user mapping for j2ee_admin , i chose my system alias and gave r/3 userid and ppwd which have access to bapi's.

however with your comments i tried on client 100 too but its still failing.

>My guess is that the j2ee_admin doesn't have the access in the ABAP system > to these BAPIs as well

Can you please elaborate on thisas i din understand it . j2ee_admin is EP's user , so does taht mean i will have to give j2ee_admin more rights so that it can access BAPI's fos some other system(in my case another r/3). if yes how do i do so ?

and major doubts , do i have to give gateway host , gateway port and logical system name ? i had read they are optional ?

and major thing is that the Transaction ivew works for this system , client both 100 and 000. but the real connection test fails so does it fails in VC while accessing data services

When you do your user mapping it should map to a user with access in your R3 system so j2ee_admin won't be required on the R3 system.

Definitely do this on client 100. If the connection test is failing, I would check that your proxy isn't blocking you. If the connection test is successful and you're getting issues from the VC side, turn on the logs based on this guide and post them here:

I had done the proxy settings following your weblog regarding proxy settings

this one

<a href="/people/prakash.darji/blog/2006/10/10/external-web-service-proxy-configuration-for-visual-composer:///people/prakash.darji/blog/2006/10/10/external-web-service-proxy-configuration-for-visual-composer

is this the proxy settings you are talking about or some other proxy settings that might be blocking me ?

really tired now , i mean if so minimal configuration is required to connect to r/3 dedicated server than why is it failing ?

<b>did u read my settings in the beginning , where they exhaustive ? or have i missed anything ?</b>

Those are the proxy settings. I read your settings and they look ok. That's why you need to debug using the logs.

ok Mr.Prakash

but since the error is at ep itself i will haev to check ep logs in detail , dont know where, presently i m only checking trace files and they are of no use, they are just diplaying the error messages and not the real causes.

is there a way to start ep logs also so that everything gets displayed ?

The above guide mentions the components to turn logs on for. This can be done in the Visual Administrator Log Configurator.

thanks for your help , will try to do it , else will write tomorrow , hope i get this done , my real work has left behind and all the time has gone into this configuration and my xApps certification is on 11th december.

have one major doubt apart from this....

i had posted one question on Portal regarding whether i can access web services of a j2ee application but din get any reply. do u have any idea if thats possible.

as i said i have to read materials from r/3 and put them into my database using my j2ee aplication.

so this j2ee application is like any other j2ee application taht i have deployed on web App Server of SAP , but again on some diffferent machine. this application exposes webservices which can be accessed when i run this application. i have accessed them using XML SPY tool .

can i access them using VC too. presently when i define a web service system and give url of my webservice's wsdl it says " InValid Web Servie Url "

Please let me know if this can be done ?

Yes, you can very easily access web services. There are numerous blogs on SDN based on this (See Scott Cairncross's weblog series) and is mentioned a ton in the online help as well.

Just one small comment, when you are rested tomorrow morning: VC installation and connection configuration is of course never done by a BPX or business user, but always by an admin.

Like with your car: you would never fix the engine or electronic of a modern car yourself, but have the mechanic fix it. And yes, driving should be what you do and have fun

The name or password is incorrect. Fix that, and also give the user appropriate authorizations.

hello mr.Prakash , the name and password are correct coz as i said it logs in using transaction ivew.

one thing i will be really interested in knowing is that, on r/3 side do i need to do anything apart from creating a user (and give him roles and profile ) which i am using for user mapping in EP.

somwhere in r/3 system do i need to make any entry of my NW system ?

and one more question what is this logical system option in connector properties ? how do i create it and which logical system do i give. some logical system in r/3 or a logical system created in my NW.

Hi Rohit,

Just tested without Logical system , it works.

With these min. settings I'm getting success in 'Connection Test for Connectors'

Even I've tried to create new sap r3 connection , and it's working.

May be have to do with User Roles.

Just go thru the 'How To Resolve Visual Composer Issues' , see page 44 , You have to make some settings in the Visual Administrator.

You can get the link to guide from the url below ,which is second post in the Foum

Bye,

Ajay

Try This :

1. System Admin>System Configuration> your R3 Connection -->Display:Permissions: here include VCRole as Owner

Also include VCRole to the user.

2. My Connector settings: ( pls confirm the settings with your admin )

Application host: nnn.nnn.nn.nn

Gateway host: leave blank

Gateway service: leave blank

Logical System Name : sid + client #

Remote Host type :3

SAP Client: <<nnn>>

SAP System ID : <aaa>

SAP system Number:00

Server Port:3200

System Type: SAP_R3

Trace Mode

3. Pls log in as administrator and test the connection and assign VCRole to Administrator.

Hi ajay , tried all this . though not sure about the logical system , is it mandatory ?

and also whether u are able to access BAPI's in VC with these minimal configuration ?

did u have to assign any extra rights to VCRole for accessing these r/3 bapi's ?

1. Modify the User Management Authentication Ticket Type: Blank

2. Go to User Admin URL : http://server:port/useradmin/index.jsp -->Identity Management - Get the user -- Go to Details of User >Check Modify> got to user mapping tab-->select your R3 connection here and enter r3 user name and password in the Mapping data.

3.Search and run the SAP Log viewer in directory :\usr\sap\J2E\JC01\j2ee\admin\logviewer-standalone\logviewer.bat

4. In Log Viewer go to x:\usr\sap\j2e\jco1 >J2E>cluster>server0->log>vcserver , here you can see the VC errors.

5.Go to R3 and run st22 and see whether user have access to run RFC.

Bye,

Ajay

hi ajay , i made the changes u said. <b>made User Management Authentication Ticket Type Blank</b> and checked r/3 , for the user i have used in User Mapping , it allows transaction st22 .

however the connection tests are still failing , so is VC failing when it tries to access this r/3 system's Data Services.

Its really frustrating , its my 4th day into this , is my way of defining system right ? i had read we have to define some read rights or somethign to VCRole, did u do any such thing ?

Please let me know in details.

here is the trace of the log file
