Import RFC Model

All,
I'm using Sneak preview full java version. When I try to call SAP Function module from webdynpro Java via RFC Model, it's asking me to specify the SAP Server detail logon information.
Can anyone help me what information i should give becos im using Sneak preview Java version...
Thanks..

Hi Bharathi
If u want to import Adaptive RFC Models from ABAP backend u have two ways for importing the model
1) single server : where u need to specify ABAP system creditials such as Application server name,client,system number for ABAP system available in ur Local Area Network
2) Load Balancing : Here DropDown List is automatically populated with list of ABAP servers which are defined in ur SAP LOGON PAD . Actually NWDS picks up names of these servers from saplogon.ini file which stores all ABAP servers defined in ur SAP LOGON PAD
so if u have entry for the required ABAP backend in ur SAP LOGON PAD then u can go for Load Balancing method in which most of the entries will be automatically populated from saplogon.ini file
If u donot have SAP LOGON PAD or saplogon.ini file doesnot have entry for the ABAP server then u should go for single server mode for Importing RFC models
Hope u Got the difference between the two methods now

Error while importing a Adaptive RFC Model

Experts,
I am trying to import an Adaptive RFC Model. Before importing I need to speciy the connection parameters in the import wizard. I am using the single server method to connect and have specified all the parameters correctly. I have not specified a SAP router as I am using a test system. when I click next on the Model import wizard I get an error.
The trace shows-

Login failed error while importing an adaptive RFC model

Hi there,
I am trying to import a adaptive RFC model for a BAPI from a 46D system, to which I have connected using VPN from my WAS J2EE server. I have given the login details as Single server(Not load balancing), and given the user login details. However, I am not able to proceed further because it gives me the error 'Name or password is incorrect, please re-enter'. This is strange because I am giving the correct name and password, and I am able to login to this system through SAP GUI using same logon credentials.
I am confused as to what it is expecting to move forward. I have tried changing case of the user name, restarting my WAS etc. The client is correct, and the login language is EN.
Could anybody have any clues or have you faced a similar problem?
thanks in advance,
LM

I have had the same problem.
I think whoever programmed the logon routine at that point should be fired immediately and banned from programming for life! Logging on is a very basic and well-understood task, and programmed gozillions of times since 1940s. Common sense and unwritten rules of programming dictate simply if you make something case-sensitive, then you should accept an input in its original form (i.e. password in smalls, or whatever) but not change it to uppercase and then work case-sensitively. Either this, or you program everything case-insensitively.
Fire that programmer or give him to us gollumvoice

Error in Import Adaptive RFC Model

Hi SDN,
I am trying to develop an application using Import Adaptive RFC Model, while creating a model i could not able to connect to the backend system after giving the single server parameters. When i click on the next button a pop up is displayed with an error message *"User Name or Password wrong" *.
But i could able to login to R/3 with the same userid and password from SAP logon pad.
Really i am at Six and Seven's to trace out this error. Please suggest me how to overcome this error and create the model succesfully.
Regards
Basha

Hi Praveen & Chaitanya
Thanks for your quick response and informative threads.
Actually in order to import an adaptive rfc model
I have right clicked the model node to create a model and given the model name,package name,model data and metadata names and clicked next button. Then in the next screen
Tab Strip -> Single Server:
Host name :
System Number :
client details:
Tab Strip -> Load balancing:
System :
Message Server:
System Name:
Group:
(in Tcode: SLMG i have added the group public also)
client details:
After entering the required details either in Single Server or Load balancing and clicked the next button I could not able estabilish a connection to the backend R/3 and get the list of Bapi's or RFc's. Instead i am getting a pop up message "User Name or Password Wrong". I could not able to proceed from here.
But with the same above parameters i could able to logon to R/3 from SAP Logon Pad. I have tried by giving the user name in Cap's and small letters but no use.
As i was strucked at the intial step while creating the model but not during the execution of the program, as far as my knowledge is concerned i think we no need to worry on SLD or JCO connections during the creation of the model. Please correct me if i am wrong and suggest me to rectify the error.
Regards
Basha

Importing adaptive RFC model in NWDS CE 7.1 doesn't work

Dear all,
I am unable to create an adaptive RFC model in my Web dynpro DC in NWDS CE 7.1.
This is what happends:
I select create model from the web dynpro, fill in name and jco destinations on the first page and move to the second page where I fill in SAP login information.
After clicking next I come to "Select RFC modules", but I never see the studio logging in to the server system. The result is that I dont find any function modules when i click search.
I am new to NWDS 7.1 so I suppose there is a setting that I have missed.
Have anyone else experienced the same problem and solved it?
I currently have an old SAP system (NW04) and a new system (NWCE7.1). On my PC I have installed NWDS 04 and NWDS CE7.1. The old studio can connect to both the new and old backend system just fine but the new studio cant connect to any of them.
I am very grateful for any help or pointers in the right direction.
Sincerely,
Richard Linnander

Never mind. I solved this myself.
It was caused by DLL-hell. I was running an old version of librfc32.dll that was for NWDS 04. Works fine with the version that comes fresh with install of NWDS CE 7.1

Changing the default logical system names for adaptive RFC models

Hello,
When I create an Adaptive RFC model the dialog that asks me to specify the model name, package, source folder, etc. has default values in the "Default logical system name for model instances" and "... RFC metadata".
I know I can type in another name there but I'd like to change the default name to something that fits our naming conventions. Can I change that? If so, can someone tell me where?
Thanks in advance!
David.

Suresh,
Thank you for your response. However, that is not what I was looking for. Sorry if my post was not clear.
I knew that I could change it AFTER the import. I also know that I can type in something else besides the default DURING the import.
What I am asking is if there is a way to change some configuration setting so that the 'default' that comes up in the drop down DURING the import is something different than what comes 'out-of-the-box' with NWDS.
Hope that clears up what I'm looking for.
David.

NWDS import RFC interface for the structure issue??

Hi Gurus,
I'm working on the SAP NetWeaver BPM with NWDS 7.3 SP12 rite now and got confused about the RFC interface structure stuff.
I have a mapping activity defined in the process and the receiver interface needs a RFC. So I go to "Process Modeling" -> "Services Interfaces", right click and choose "Import RFC",type the correct RFC/BAPI name connecting with the SAP ECC system. The issue is that when I finished importing the RFC, went to the "Data Types", the RFC interface namespace shows out but the structure shows seperately with individual segment, so the whole nested RFC interface structure messed up in parallel which is incorrect for the data object and output mapping for later process activities.
Anyone has ran into such kind of issue or experience the same, any solution or suggestion?
Thanks in advance,
Rajesh

William,
Another two questions relates to NWDS BPM development:
1. Sometimes after I import the service interface into NWDS, the structure displays differently from it defines in ESR, I mean the fields sequence. I dont know why
2. Refer to your screenshot,
Assume the occurence of node HEADER and item is (0..1), when I want to map a blank constant to them to generate the target structure, the editor not allows and display error which is very different with ESR mapping tool, could you please help to advise? Tons of thanks!
Thanks a lot in advance,
Rajesh

Why We Call Adpative RFC MODEL?

Hi ,
Why We Call Adaptive RFC MODEL?
What is RFM?

Hi Subbarao,
The Adaptive Remote Function Call (Adaptive RFC) is a technology that enables the Web Dynpro application developer to use the business functions encapsulated in Business APIs (BAPIs) even after a structure modification, without having to provide the new data using a second back end or a new structure with subsequent regeneration of the proxies.
This new RFC model shows adaptive behavior. This means that the RFC proxies do not use the original design time structure definition at runtime. Instead, this Web Dynpro model automatically adapts the data of the structure passed in the Java proxy generation to the current data that is, a structure definition in the back-end system that may have been modified
For more info go through this link..
[Adaptive RFC|http://help.sap.com/saphelp_nw70/helpdata/en/6a/11f1f29526944e8580c5e59333d96d/frameset.htm]
Importing RFC's
__http://help.sap.com/saphelp_nw70/helpdata/en/6a/11f1f29526944e8580c5e59333d96d/frameset.htm__
RFM - stands for Remote-enabled Function Modules, amd you can learn more about it from
http://help.sap.com/saphelpnw70/helpdata/en/22/0427c0488911d189490000e829fbbd/frameset.htm_
Difference between BAPI and RFM --
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects.
You create business objects and those are then registered in your BOR (Business Object Repository)
which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA.
In this case u only specify the business object and its method from external system
in BAPI there is no direct system call. while RFC are direct system call.
Hope this helps,
Reward Points if helpful,

Why SLD for Adaptive RFC Model?

Hi,
Is it necessary to configure the settings in SLD in order to run an adaptive RFC Model or does one have alternatives?
Because, while defining an adaptive RFC Model in NW-Dev-Studio, one does explicitly enter the SAP Log on information.
Regards
Meesum

Hi,
SLD is required to run the RFC application.
At design time there is no dependency on SLD and we are not going to specify SLD details during the model import.
Runtime will pickup the connection info from ContentAdminstrator where we will point to SLD.
Regards, VIP

Export of RFC Model to Java Project DC ?

I've got a Web Dynpro project where I used the Wizard to import an RFC Model. Now my client has this requirement that all Web Dynpro Models should be based on Command Beans that reside inside their own separate java DCs.
My question : is it possible to export my RFC Models packages and folders (along with my other Model classes) to a java DC project - to be later reimported back into the Web Dynpro project ?
Thanks for any input on this

Hi Romeo,
To answer your question first there is no standard supported way in which you could expose RFC Model in seperate Java DCs.
If the question is just to have the classes (proxy) created for RFC to connect to r/3 and get the data then you could use SAP Enterprise Connector, but i would not recommand that as you loose out the complete declarative way of using RFC and so called CMI Model support for Web Dynpro.
Secondly if RFC Model which you are planning to expose as part of java dc has to be consumed in Web Dynpro then i do not understand the need why some one will require to expose the RFC Model in Java DC and the inherit concept of RFC Model is related to Web Dynpro and not with normal Java DC thus its a matter of choice do you want to use plaiin java classes without Model driven approach or more declarative way as in case of Web Dynpro.
Thanks

Using an Adaptive RFC Model from JSP

I'm trying to use an Adaptive RFC Model I created for use in our Web Dynpros from a Portal Application project. I've created 2 DCs:
1. A Web Dynpro DC, only containing the imported Adaptive RFC Model. The model has been added to the public parts.
2. A Portal Application DC, with the model DC added as a DC usage (along with the other required DCs)
Now, everything appears to work from inside NWDS. The dot operator works while editing my JSPDynPage class, and everything builds fine, but when I deploy and test in the portal, I get "package not found" errors on the actual JSP. I assume this is because the JSP is compiled at run-time. How do I expose these classes to the JSP compiler?
It's seems like using the same method to call BAPIs in Web Dynpros and Java iViews would be a good practice following SAP's "reusable code" policy, so there must be a way to do it...

Jonathan,
Adaptive RFC Model works correctly only when running inside WebDynpro container. JSP runs outside container (in regular J2EE WebApplication container).
The error you receive is due to missing run-time references to container classes.
Actually, what you are trying to do is dead end, sorry.
Use SAP Enterprise Connector instead of Adaptive RFC model. Generated connector classes works from any environment. Also they are sooo similar to Adaptive RFC that you'll even not mention a difference.
