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.

Metadata Cache Invalidation for Adaptive RFC Models

Hi,
Im trying the tutorial of the document: Metadata Cache Invalidation for Adaptive RFC Models.
Ive downloaded and deployed the EAR for NW7.0 on my server, but when I try to list the JCO destinations I have the following error:
java.lang.NoSuchFieldError: flush_cache
at com.sap.invalidation.InvalidationView.onActionGetSLDJCOs(InvalidationView.java:215)
When I try to invalidate a dictionary, I have the message:
Cache for Dictionary com.unilog.product.search.model.types.SearchProductModel invalidated
But the tooltip value is not updated in my application...
Can anyone give me some tips to use this component?
Thanks in advance.

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.

Deployment: Metadata Cache Invalidation for Adaptive RFC Models

Dear SDN Member,
I have deployed the new "Cache Invalidation" Tool at our portal NW04s SPS12.
We have deployed the tool by using the sdm.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/10465350-b4f5-2910-61ba-a58282b3b6df
The entrypoint is not visible in the webdynpro console navigation.
What have I done wrong?
Best regards,
Olaf Reiss

Hello,
we also deployed it to our NW04s SPS12 Portal (since it was NOT included in SPS12)
We deplyoed the correct version. For us it is also not visible in the NWA.
However, it can be called from the Webdynpro console. Then you see it has this direct link.
http://<server>:<port>/webdynpro/dispatcher/local/InvalidationTool/Invalidation
However, the thing still has bugs.
Clicking the button "Get JCO destinations" just crashes with a 500 error (see below). Our developer said
The initial exception that caused the request to fail, was:
 java.lang.NoSuchFieldError: flush_cache
 at com.sap.invalidation.InvalidationView.onActionGetSLDJCOs(InvalidationView.java:215)
 at com.sap.invalidation.wdp.InternalInvalidationView.wdInvokeEventHandler(InternalInvalidationView.java:236)
 at com.sap.tc.webdynpro.progmodel.generation.DelegatingView.invokeEventHandler(DelegatingView.java:87)
 at com.sap.tc.webdynpro.progmodel.controller.Action.fire(Action.java:67)
 at com.sap.tc.webdynpro.clientserver.window.WindowPhaseModel.doHandleActionEvent(WindowPhaseModel.java:420)
 ... 26 more
Using the lower part and option 2.
("Dictionaries Cache Invalidation" and "Enter Dictionary") is said to be working, if you exactly know the naming.
But how can we invalidate the RFC caches used by Visual Composer?
In Visual Admin/services/Connector Container/../SapFactory/Managed conenction factory/ConnectionDefintion I have already set the Connectionlifetime to 60 and ticked "expiraation" ?
Best regards
Ulf

Adaptive RFC Model - disconnectIfAlive()

Hi,
In my Web Dynpro application, I am using Adaptive RFC model and executing the RFC as below
ZRfc_Test_Input input = new ZRfc_Test_Input();
// set input
input.setParam1("xxx");
input.setParam2("xxx");
input.execute();
My application works fine for couple of days and suddenly I get an error that
"com.sap.tc.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCExecuteException:Could not create JCOClientConnection for logical System: WD_TEST_MODELDATA_DEST - Model: class com.test.TestModel. Please assure that you have configured the RFC connections and/or logical system name properly for this model!"
Our basis guys are unable to figure out why the SLD is misbehaving suddenly. If we restart the SLD, everything will be fine for next couple of days.
I just want to make sure that it is not happening due to my application or due to the way the RFCs are being executed.
After I execute my model, do I have to explicity disconnect the connection using below statement?
input.modelInstance().disconnectIfAlive();
Do I have to do this even when I am using Adaptive RFC model?
Default min and max number of connections are used while creating JCO destinations.
Appreciate your input.
Thanks
Kumar

Hi Siva,
>>> It is always better to close the connection after executing the RFC<<<
Thanks for the response. I am sorry for being adamant, I agree that it would be nice to disconnect but IS IT MANDATORY? If the pool size is increased appropriately, doesn't web dynpro runtime takecare and disconnect the connections after the execution.
In SAP tutorials and help.sap.com (at least the ones I have gone through), it is never mentioned any where that one MUST close the connections EXPLICITLY after the execution. All these days I am under the impression that it is not needed for Adaptive RFC models. I may be wrong.
Could you please confirm if we should close the connections explicity?
Thanks
Kumar

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,

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.

Basha

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.
Thnks,

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

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.

Ervin

Adaptive RFC model connectivity to SAP R/3 4.6 B

We are developing a new webdynpro application which uses the backend R/3 version is 4.6B using Adaptive RFC model.
We are able to connect to Web As systems without any issues but getting error messages while creating the Adaptive RFC model to R/3 4.6 B system as backend.
Appreicate your help.

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

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,

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.

How to set the tables parameter to a BAPI using adaptive RFC model

Hi,
I have a BAPI ZBAPI that has a tables parameter ZPernr of type ZTable with two elements pernr and name.
I used adaptive RFC model and created model classes for the BAPI.
My question how do i set list of pernr and name to the tables parameter in the webdynpro for java.
I have the following methods available
ZBAPI input = new ZBAPI();
1.ZTable table = new ZTable();
table.setPernr(pernr);
table.setname(name);
input.addZPernr(table);
how do i set the table parameter for multiple pernr and name
2.
add all the pernr and name to list and set that list to input in the following way
input.setZPernr(list) and list of typecom.sap.aii.proxy.framework.core. AbstractList
out of two methods mentioned which one is correct.
Please let me know the solution
Thanks
Bala Duvvuri

Hi Bala,
 In your code:
List pernrList = new ArrayList();
pernrList should be declared as the type of class HROBJECT ( The structure name in the model e.g. the node PERFWARN type is Zhrecmfm_002_Perfrat_Warning_Input )
Try this:
HROBJECT pernrList = new HROBJECT();
pernrList.setPernr(pernr);
input.setPernr_List(pernrList);
// call BAPI execute method
If you want to pass list of pernrs, you can pass in alternate way
IPrivate<viewname>.I<nodeame>Node prNode = wdContext.node<node>();
IPrivate<viewname>.I<nodeame>Element prEle;
for (int i = 0; i < table.size(); i++) {
HROBJECT pernrList = new HROBJECT();
pernrList.setPernr(pernr); // Set the pernr from current record
prEle = prNode.create<nodeame>Element(pernrList);
prNode.addElement(prEle);
// call BAPI execute method
Once I execute the BAPI how do i iterate thru second table parameter PERNR_PERFRAT to get pernr and performance rating text
Say your node name is PERNR_PERFRAT
for (int i = 0; i < wdContext.nodePERNR_PERFRAT().size(); i++) {
wdContext.nodePERNR_PERFRAT().getPERNR_PERFRATElementAt(i).getPernr();
wdContext.nodePERNR_PERFRAT().getPERNR_PERFRATElementAt(i).getPerfrat();

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
