Many Adaptive RFC

hello all
I have one question about Adaptive RFC.
In my project, i have many RFC access. My question is, what best practices for import RFC. One Model and all RFC in this model?
Each RFC is a Model?
If each RFC is a model, can i set JCO name equal?
tks
Douglas

Douglas-
Here are some points to keep in mind when using Adaptive RFC Models:
1. Use the Adaptive RFC Model for accessing RFCs in an SAP system.
2. Each Adatptive RFC Model should be in it's own Java package.
3. Group Adaptive RFC Models based on functionality.
4. Never have one RFC module per Adaptive RFC Model.
5. Model your RFC so that it can be reused.
Cheers-

Invalidate the Adaptive RFC Dictionary Cache

Hi All,
I had to do RFC interface structure changes for a Webdynpro JAVA application.I had deployed the application and used the administrative function "Invalidate Adaptive RFC Dictionary Cache" within the Web Dynpro console" to explicitly invalidate the metadata cache..
Before using this tool, I was not able to run the application.This tool helped to run the application.
But When I Submit the data to the RFC from this application I get the following Exception:
com.sap.mw.jco.JCO$MetaData.getType(JCO.java:10210)
I understand from the SAP note 859950, Metadata is not invalidated without J2EE Engine restart.
Is there any update from SAP after this note..Pls let me know if some one has done a workaround instead of restarting the SAP NW Application server.
Thanks, Sethu

We went through this same issue many times and we opened an issue with SAP a few months ago.
The invalidate is very limited and does not handle a clustered server architecture. It is meant only for a single node, single server setup. All of our environments are multi-node and multi-server.
The tool will only invalidate the node that the Basis Administrator is currently logged onto. Therefore if your server architecture consists of > 1 node and/or > 1 servers then you will have nodes/servers that still have the previous version of the metadata cached.
SAP said the Basis administrator would have to log onto each node and run the invalidate tool. In a multi-node setup there is no easy way to do this because there is no control which node you will be put on. If you have 1 node per server then yes you can log onto each server and run the tool.
In the end SAP said they do not support the Invalidate tool in a multi-node/multi-server cluster.
They said to perform a J2EE restart, period.
Hope that helps.

Adaptive RFC and Locking Objects from WD Java

Hi,
There are some pieces of information available on this subject but no coherent and easy to follow "manual". Also some questions remain.
I'd rate this a very important, i.e. "business critical" problem. Therefore I would appreciate your help to get things sorted in this thread.
So let's start with a summary of what I think I understood so far (corrections welcome!):
- You can call RFCs from WebDynpro and locking will work (on the ABAP side).
- Once you release your JCo connection the locks will be released, though.
- Therefore, to keep a lock in between requests you have to keep the connection.
- You can keep the connection by passing WDModelScopeType.APPLICATION_SCOPE or WDModelScopeType.COMPONENT_SCOPE to the constructor of the model class.
- You can lookup the default scope for a model using
WDModelScopeType defaultScope = WDModelFactory.lookupDefaultScopeForModel((Class) modelClazz);
Now suppose you have many users, each holding some locks.
Would you not easily run out of JCo connections? On the other hand by default WebDynpro RFC Models seem to keep a connection per application instance (= user session).
Using WDModelScopeType: Do you really need to code this or can you just configure this during design time for the deployment?
blog=/pub/wlg/1061 claims the default is APPLICATION_SCOPE.
Will connections (and thus locks) be released automatically on an HttpSession timeout? I guess so because this means the end of the application and therefore end of scope WDModelScopeType.APPLICATION_SCOPE and WDModelScopeType.COMPONENT_SCOPE.
I'm also not clear about this:
/people/sap.user72/blog/2005/01/08/adaptive-rfc-models-in-web-dynprosome-pointers
"But to ensure that the record remains locked it is necessary reserve the connection that was used for locking and be made unavailable for other models and also the connection should remain open as long as the lifetime of the screen. This becomes similar to locking records through SAP Gui . This can be easily achieved by having separate models for locking RFCs defined with APPLICATION_SCOPE and isolating its connection by not grouping with other model objects."
What does "reserve the connection" mean?
Suppose you lock some object and afterwards want to allow the user to request more information about this or other objects.
Would you need to use a different connection for that?
Suppose you want to lock two objects.
Would you need to use two different connections for that?
Suppose you want to edit both objects and save the changes inside one transaction (with atomicity). A transaction normally is associated with a single connection (unless XA protocol is used). So how would this work?
What will cause the locks to be released?
- Application expiration (timeout)
- RFC that explicitely releases locks
- Transaction commit/rollback (?)
Reference:
I found some of the information and further pointers in the blog mentioned above and here:

Looking forward to your replies

Hi,
This for If you send destination params are different u sent it thru URL param only.
For that u need generate URL by using the application .
For that purpose u need to create two applications u can call the first application in second application u can create URL and send Destination params with URL only.
Other wise u can create the par file that would be configured in portal and thru worksets u can pass the params like u mention the destinations.
Or at the time generationg URLS only u can add the destination names.

Adaptive RFC 2 gives error: com/sap/ide/jco/service/internal/R3Service

Hi,
I've run into the following problem about NWDS. This happens as I create a Model. It appears there is a new version of the Adaptive RFC Model, which is called Adaptive RFC 2 Model.
1. Right click on Models, and select Create.
2. Double Click on Adaptive RFC 2 Model
3. The error pops up. It says "An error has occurred. See error log for more details. java.lang.NoClassDefFoundError". Then if you click details you get "An error has occurred. See error log for more details. com/sap/ide/jco/service/internal/R3Service "
If you know which log to have a look, or what this error is about please let me know urgently. Any help if much appreciated.
Thanks,

Error while creating a Adaptive RFC Model

Hi all,
I am trying to create a Model using a Adaptive RFC Model, I assign a Model name and the logical system names, enter the details in SAP Logon Information for the Single server,here it gives me a Gateway error. What could be the issue here?
NB: In the Host Name , I tried with both the Host name of the r/3 server and also with the SAProuter string ( as we have the server at other place) ,still it doesnt work. and I am able to login to the R/3 system from the SAPLogon GUI from my desktop normally.
Is there any issue of the firewall related to this, if so whats the port number that should be opened so that i can connect to the r/3 system get the list of BAPIs present there into my Webdynpro application .
Need help on this
Regards,
Vijay

Hi Lohi n Gopi ,
I have checked out with the your given suggestion of trying with the host name as well as IP address and also typing all the details,without copy pasting the details . In both the cases it gave the " Connect to gateway failed " error mesg.
But one intersting thing here that i observered when trying with hostname, IP address, or SAProuter string is as follows .
with IP address
Connect to SAP gateway failed
Connect_PM GWHOST="ipaddress",GWSERV=sapgw10,ASHOST="ipaddress",SYSNR=10
LOCATION CPIC(TCP/IP) on local host
ERROR patner not reached(host "ipaddress",service=3310)
with SAProuterString
Connect to SAP gateway failed
Connect_PM GWHOST="SAProuterString",GWSERV=sapgw10,ASHOST="SAProuterString",SYSNR=10
LOCATION SAPRouter on " some HostName"
ERROR hostname unknown
with HostName
Connect to SAP gateway failed
Connect_PM GWHOST="hostname",GWSERV=sapgw10,ASHOST="hostname",SYSNR=10
LOCATION CPIC(TCP/IP) on local host
ERROR hostname "hostname " unknown
Is there any firewall port blocking issue here ?if so , whats the port that needs to be opened ?
Appreciate your help.

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-

sapgw<Inst.No>s 48<Inst.No>/tcp
where <Inst.No> = System Number of your R/3 system(00 or 01...)
In host file....
ip of the server name of the server....

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

How to find out the destination of an "Adaptive RFC Model - DEPRECATED"

Hi All,
How to find out the destination of an "Adaptive RFC Model - DEPRECATED" of an running application
and Where is the destination created in the server .
I have got the code of the running project from NWDI .
Thanks in Advance
Regards
Piyas Kumar

Hi,
I am not sure I fully understand the question, but as per the guide
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/50f7192d-2808-2d10-189b-df3fa5f71abf
Excerpt from Page 7
Caveat Confector!1
ARFC1 destinations were created using the Web Dynpro Content Administrator tool. This tool is
still available for compatibility reasons, but the destinations it creates are not used by ARFC2
models!
Instead, you should use the u201CDestinationsu201D tool found on the Configuration Management screen of
the NetWeaver Administrator.
Therefore I think if you look up the application in the WD content Admin, there you can find out what kind of JCO/RFC connections are belonging to it. You can find it on http://<host>:<port>/webdynpro/dispatcher/sap.com/tcwdtools/Explorer
Browse your application here, and then select the JCO Connections tab on the right hand side.
I hope this helps.
Best Regards,
Ervin

Adaptive RFC model connectivity to SAP R/3 4.6 B

Hi ,
I think SLD,s/w Catalog and Creating Logical Systems were Configured,
Go through the Following Steps Like,
-- General Data, Enter the Client of the System and Client No. (JCo Connection is Pointing to)
--J2EE Cluster, Select the J2EE Cluster you wish the JCo destination to be assigned
-- Select the Destination Type, Either Application/Dictionary data
-- Appl.Server, You may only select Servers/Logon Groups From the Drop down list that have first been defined as technical Systems in SLD.
-- Message Server, Application Data JCo destination is connected must have atleast one logon group.( if this is not done ,use SMLG transaction code to create in SAP System)
--Security, If you have selected connection Type as Application Data , then in the Security Screen you would appear Authentication Techniques and select a appropriate one .
if you have selected connection type as a Dictionary meta data then provide User Name and Password
If this is useful to you ,don't forget to award Points

Looking for a beginner guide - Adaptive RFC call BAPI in Web Dynpro Java

Hi,
im new in SAP Developeing. I developed some basic web Dynpro applications (after some tutorials) and they are all working.
Now i want to build an Web Dynpro application with an adaptive RFC Model.
I already imported the adaptive RFC Modell with a function Model (BAPI Z_...) from the R3 System successfully.
But if i deploy the application i will get following error:

........Looks like a have a Problem with JCO.
Is there a good guide, which explains the Basic steps in developeing Web dynpro applications and BAPI ?!

thank you guys for all the answers.I have to read all the documentations.
to my szenario:
I installed on my notebook the Trial Versions of:
SAP NetWeaver Application Server 7.00/Java AS 7.00
SAP NetWeaver Developer Studio Version: 7.0.14
All my basic Web Dynpro Applications in Java are running (even with Adobe Interactive Forms) on the local NetWeaver Trail- Web AS Trail perfectly.
Now i want to connect per RFC to another SAPERP Server, which is in the intranet.
I did the whole RFC tutorial with the flights -
http://help.sap.com/saphelp_nw04/helpdata/en/c3/76b45d9688e04abe1a1070410ddc1e/content.htm (also with the JCO codeing etc)
so my web dynpro application should work.
I think I have to configure - like ramesh said something on the NetWeaver Trail.
So what do i need and configure excactly on my Netweaver Trial to work with RFC - to call the BAPIS in the other System?
- SLD ? JCO ?
If i over Web Dynpro - Content Administrator - >
it says "Connection to System Landscape Directory (SLD) could not be opended successfully." and all the buttons
create Jco destinations etc. are greyed out.
I didn´t configured the SLD and JCO in the Netweaver yet.

Why we call adaptive RFC in webdynpro java..

Hi,
I want to know why we call adaptive RFC connection in webdynpro java whenever we import new rfc in our java web dynpro project. why name ADAPTIVE RFC is used
if we make any structure changes in the model which we imported in web dynpro project , like adding a new field, or changing the length/datatype of the existing field, then we always have to reimport the model in our webdynpro project so why adaptive name used. wats especial in the word ADAPTIVE RFC

Hi Rahul,
please read the guide:

Mapping with multiple Adaptive rfc's

Hi Experts,
i have 4 radio buttons, i need to create a single adaptive rfc model, to which i need to create a one ECC system rfc and APO system rfc(multiple backend systems). how to add the two rfc systems of logical system name to a single logical system name or Meta data, so that i can assign to a single radio button.
In the same way for model data also if so how?
1. radio button(Ecc rfc and Apo rfc)
2.radio button (Ecc rfc and Apo rfc)
3.radio button(Ecc rfc and Apo rfc)
4.radio button (Ecc rfc and Apo rfc)
help me in doing step by step.
thanks in advance
Thanks&Regards

Hi Bhargava,
thank you for your effort.
The node structure of web service looks like this:
NewAWS2Model
-Context
Number
NameFirst
NameLast
Street
HouseNo
PostCode
City
-NewOperartion
In
-Request_NewOperation
---NewOperation
---Response
-Response_NewOperation
This web service give no response back. He just starts the BPM Process. Everything works well, except for passing ALL values of the parameters in Context: Number, Name, Street...
When I have two streets, I want that two streets will be saved in parameter street and so on...
Additionally, here is the method created by application for this web service:
public void initRequest_NewOperation( ) {
    //@@begin initRequest_NewOperation()
    //$$begin Service Controller1(-482113598)
com.sap.demo.changedataportaldc.wd.models.newaws2model.NewAWS2Model newAWS2ModelModel = createAndMapModelInstance_0("com.sap.demo.changedataportaldc.wd.models.newaws2model.NewAWS2Model");
        com.sap.demo.changedataportaldc.wd.models.newaws2model.Request_NewOperation request_NewOperation = wdContext.nodeRequest_NewOperation().createAndAddRequest_NewOperationElement().modelObject();
        com.sap.demo.changedataportaldc.wd.models.newaws2model.NewOperation newOperation = new com.sap.demo.changedataportaldc.wd.models.newaws2model.NewOperation(newAWS2ModelModel);
        request_NewOperation.setNewOperation(newOperation);
        com.sap.demo.changedataportaldc.wd.models.newaws2model.Context in = new com.sap.demo.changedataportaldc.wd.models.newaws2model.Context(newAWS2ModelModel);
        newOperation.setIn(in);
        com.sap.demo.changedataportaldc.wd.models.newaws2model.Response_NewOperation response_1 = new com.sap.demo.changedataportaldc.wd.models.newaws2model.Response_NewOperation(newAWS2ModelModel);
        request_NewOperation.setResponse(response_1);
I hope this are the inforamtion you need? Or is there something else?
Thank you very much
best regards
Anna

Problem in displaying a field in webdynpro using Adaptive RFC model

HI,
I created a webdynpro application using adaptive RFC model and i have a problem in displaying one of the output fields.
When i execute the function module it is giving the exact value for my output field in this case telephone number (of type STEXT which is char with length 40).But when i am trying to display that telephone number in webdynpro application it is taking only first 4 digits.
i deleted the model and recreated it still it doesnot work.
please let me know how to resolve it.
points will be awarded for sure
Bala

Hi Bala,
Whenever you reimport the model server restart is necessary otherwise the changes will not get reflected. You will get an error when you deploy the application.There is no go around except restarting the server as the meta data gets cached in the server as long as the server is runnig.So, Once you restart the server the cache will be cleared.
Check once again whether you are fetching data from correct BAPI field. Still problem persist try debugging.
