Error in using Adaptive RFC

Hi,
I am using an Adaptive RFC to display values in a table in Webdynpro.There is an error " com.sap.dictionary.runtime.DdException: Value is not numeric " which occurs when I try to display the data.
Could u please tell me what could be the reason for the occurence of this error.
Thanks in advance,
Jesmila.

Hi
1.Test the return Data are corectly bind with the same data type.
2. Check the output node size is greater then 0.
Can you expalin the problem in detail?

Error while using Adaptive RFC model

I am using adaptive RFC model to consume a function module from BI system. The function module expects a Boolean input. While executing the function module we need to give u2018Xu2019 for that input. When I consumed the function module in the webynpro java project , used it and give the input as u2018trueu2019 on runnig the application it gives the following error: u201Ccom.sap.conn.jco.ConversionException: (122) JCO_ERROR_CONVERSION: Cannot convert a value from type java.lang.Object to CHAR at field I_READ_ATTRu201D
There is corresponding dictionary type created called u2018BOOLE_Du2019 but I could not access the dictionary type in the controller java file.
Is there a way to rectify the same or any workaround condition?
With regards,
Sougato.

Hi saurabh,
I need to give the value from webdynpro. Hers is the sample code.
rssem_Cha_Values_Get_Input.setI_Read_Attr();
// It expects a boolean value but if i pass a value to the method the obove error is show.
Where as there is a simple type "Boole_d" generated when i consumed the RFC in the webdynpro.
but i couldn't access this simple type in the code.
With regards,
Sougato.

Getting Error when using Adaptive RFC in creating model...

Hi All,
When i am creating Model for Adaptive RFC at that time i am not able to login to my R/3 System...
Previously we used to work in ECC5.0 at that time it was working.
Now we are working in ECC 6.0 but error is coming. Name and password not found.
So do i have to reconfigure the NWDS.
If Yes. How to do reconfigure it for ECC 6.0

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();

Inconsistency of results using adaptive RFC

I'm calling a function from a R/3 System using Adaptive RFC and i'm having different results from my webdynpro application that the ones that i'm having in the R/3.
If someone could tell me why this happen I will appreciate.
Thanks.

Hi Frank,
Iin another opportunity I had tried to do the same procedure you are trying and not getting hit. I ended up using the parameter "sap-wd-client = WmlClient" in the url of the application ... What makes this return in xml format and can be accessed like a Web Service. It really is not a proper use for a Web Dynpro application, but with some customization finally meet demand.

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

(SUP for Blackberry) JCo unknown type error when using PT_ARQ_REQUEST* RFC

Dear community,
I am encountering a weird error when trying to execute the PT_ARQ_REQUEST_PREPARE RFC in a Leave Request scenario for BlackBerry with the SUP.
When creating the MBO from the RFC PT_ARQ_REQUEST_PREPARE and testing it with the parameters
im_command = create
im_modus = r
im_pernr = 00001000
im_wi_id = 000000000000 (initial value)
im_request_id = *emptyString* (initial value)
I get an "execution suceeded" everytime EXCEPT when I try to return the output structure ex_request! However, this is exactley the information needed to execute the following RFCs PT_ARQ_REQUEST_EXECUTE and PT_ARQ_REQUEST_CHECK. The error I get when executing is the following:
unknown JCO type
java.sql.SQLException: unknown JCO type
I checked for short dumps in the transaction ST22 and found an OBJECTS_OBJREF_NOT_ASSIGNED_NO (CX_SY_REF_IS_INITIAL) error that marks an error when retrieving the attributes (most likely from the ex_request structure). I looked at the structure and found out that it is a deep structure. Could that be the reason for the error? How can I fix it and get the correct output? Does anybody has experience with a similar problem?
Thank you for your help in advance!
Best regards,
Jenny

Hi Jenny,
I can't remember what the issue exactly is but I think it's related to one of the data types used in the returned structure.
In any case it's probably a good idea to create your own RFC enabled function module to call the 3 standard function modules instead of calling them one after the other. This way you will avoid unnecessary network communication and you have more control on the data that is exchanged.

Programmatic access to multiple backend systems using adaptive RFC

Hello,
The following link http://help.sap.com/saphelp_nw04/helpdata/en/af/84a34098022a54e10000000a1550b0/content.htm talks about the support to map multiple backend systems by specifying the backend system as URL parameters in a webdynpro application.
For example:
http://<hostname>:<port>/webdynpro/dispatcher/local/ESSProject/ESSApp?
sap.wdarfc.useSys=WD_MODELDATA_DEST:ABC&
sap.wdarfc.useSys=WD_RFC_METADATA_DEST:ABC
Is it possible to programmatically change the backend systems the application connects to? in other words can a single application while executing connect to different backend systems by dynamically changing the model parameters?
(This should be possible without the portal in the picture)
Cheers,
Praveen

I tried to reimport the model, but didn't work.
The RFC Destinations are created and working.
Someone could help me, please?
Regards
Marcos Brandao

Hi Marcos,
I would rather say first check the status of JCOs. Then delete the model node from context and even from DC. Now freshly import the model, create a model node in context and then bind it to the input structure of the BAPI before you call the code.
Even in the code, check if you bind the instance of input structure of the BAPI to the model node in conext before you execute the model instance.

Error msg-Adaptive RFC reimport could lead to inconsistency of R/3 metadata

Hi Experts,
I am trying to reimport the model for Webdynpro application.
I wanted to include more BAPIs to the existing model.
When i am trying to do that I get pop up, with following message;
"Adaptive RFC reimport could lead to inconsistency of R/3 metadata cached on J2ee server.
Thus it is recommended to invalidate the cache this could be done either by re starting the J2EE server or by using adaptive RFC metadata cache invalidatation tool within webdynpro Console"
Could anyone one help me in resolving this?
Thanks and regards,
Pradnya

Hi,
When you reimport an RFC/BAPI the metadata which is stored in the cache is not cleared. So it still refers to the old RFC/BAPI metadata. We need to clear this. This can be done by either restarting the server or webdynpro console.
For Clearing through webdynpro console the version should be NW04 or 6.40 SP21 Onwards 2. NW04S or 7.0 SP12 Onwards
Check this link.

Adaptive RFC use in test/dev systems

The Adaptive RFC model requires a msg.server for metadata. Does that mean it can't be used in test/dev system where there is only an app server? I find that hard to believe.
Secondly, during the creation of JCO Connections in the webdnypro content admin tool, the drop down boxes for message server and application server are empty. where is this data defined? saplogon.ini + ...drivers/etc/services files were copied to the WAS/SLD host machine.
Furthermore, is the Adaptive RFC the best way to use SAP data (called from function modules) in a webdynpro?
Thanks,
faB.

Hi,
1.Even in development system you have centrall services, and as part of this you have a message server. So you can use Adaptive RFC model in development sysetems without any problem.
2.Regarding you second question: you should define you application system in SLD before using JCO destinations. Just search for SLD in this forum and you will fine the how to configure it.
3. AFAIK, Adaptive RDC model <b>is</b> the best way (it's better to say the <b>proper</b> way) to use your SAP application system in the WAS context.
Hope it helps.

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
