Acessing Infotype from RFC

Hi
I need to show some infotype data in a table, in Webdynpro Java.
ABAP developers will develop a RFC to provide that data, but my question is "Since the infotype structure is returned dinamically through RFC, what if someone update the data type in SAP System dictionary? Do I have to change my Webdynpro application? Or my model will adapt to that update automatically?
Thanks in advance

if RFC type changes after importing to webdynpro, we need to re-import the model and restart J2EE server to reflect the changes.

Prob. exec. print job from RFC which im calling Web Dynpro java in Portal

Hi,
Ive got a problem executing a print job from an RFC which im calling in Java web Dynpro Application in Portal. Im using an Acess Method G: for Front End Printing but Order gets stuck with the Status "Waiting" "Front end unavailable".
Any help would be greatly appreciated.
Thanks in advance!!!

HI,
I dont think you would be able to do this. Instead, you need to get the content from RFC into WD java and print from the browser.

Error 500--Internal Server Error From RFC 2068 Hypertext Transfer Protocol

We are encountering the following error while navigating the dashboards/ reports through OBIEE: "Error 500--Internal Server Error From RFC 2068 Hyperion Transfer Protocol"
While navigating from one dashboard page to another this error is encountered or we get kicked out of the session and need to log back in.
Any one experienced the same before?

Thanks Srini.
They issue we are facing is not post-installation specific. The environment functions fine but when we navigate dashboard pages, then this error pops up. It is intermittent and applicable to certain dashboards and reports. Not sure if you have ever encountered the dashboard/ report design causing this?

Web Service from RFC function module

Hi all,
I'm searching for a way to create web services from RFC-enabled function modules. I know there is a wizard, but it's not suitable for my problem:
I have around 30 function modules (number raising in near future) I want to enable for web services, most of them share the same structures representing the underlying data model. When one structure is modified (i.e. a new sub-structure is added) I have to recreate all web services, which is quite uncomfortable.
In addition, using the wizard results in one wsdl-file for each web service operation, that leads to an administration overhead using this web services from a java frontend.
So I'm searching for a "bulk creation". I also know the wizard can be used for a function group, but I can't put all my RFC-enabled function module in one function group, that would lead to confusion in the package.
Does anyone know how web services are created programmaticaly? If I had a function module which creates the web services I could write a function module which creates all web services I need.
Thank you in anticipation!
Florian

I'm not sure I understand the 're-create' part...how are you re-creating the web service? if you modify the interface of a function-based web service, then you use the 'modify operations' functionality (context menu - right-click) to regenerate the web service interface; this works for a function group based web service as well and hits all of the methods at once. As for the java overhead on function group services, stating the obvious, maybe you just need to lower the number of functions in your groups. We use .Net-developed applications with multi-function webservices and don't have any overhead issues.

Procedure for Mapping two types of Idocs from RFC function Module

Hi
My Scenario is RFC -- XI -- IDOC
Here i have 2 custom Idocs
First IDOC for Creation
second is for Deletion/Changing
Based on the condition from RFC it should trigger either one of the IDOC above.
Please provide me the procedure to do in IR and ID..
Regards,
Yeswanth.

YeswanthRaj:
I found your conflicted statements
The following statement you say you just have one receiver, to receive two IDOCs
But i have only one receiver where the 2 IDOcs needs to be send based on the condition..
The following statements showing that you have more than one receiver,
the condition editor for receiver determination usually used for multiple receivers based on XPATH or Context Object condition
It is mapped based on the condition that is given in Receiver Determination and i has two interface Determinations.
It seems that the first scenario is your situation.
If your answer is yes, and your source interface is just one,and target interface is two (two IDOC), then this should be typical
muti-mapping scenario, and the propose I gave to you should fit
Regards.

Is it possible to make a call to an Infotype from an ABAP program?

Dear friends,
I created a new infotype 9*** using transaction pm01 and it works fine. What i need to do is to make a call to this infotype from an abap program without going through transaction pa30. Is it possible to do that? Thank you in advance.
Sincerely,
hajar

Hi,
The HR_MASTERDATA_DIALOG might need some tweaking.. we use a custom Program on the lines of SAP's
'perform rp_infotyp(sapfp50g)' that is more user friendly.. let me know if u need more info..
Good Luck,

Reg: Proxy error while fetching data from RFC's

Hi All,
I am fetching data from RFC's. When the data is in bulk I am getting an error like:
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /webdynpro/dispatcher/sap.com/pb/PageBuilder.
Reason: Error reading from remote server
When the data is samll only I am not getting any error and am able to fetch it easily. Please suggest me something in this regard.
Thanks in advance,
Gaurav

Hi Detlef / Gowtham,
Now I am able to fetch data from flat files from OWB Server as well as OWB Client.
One way I have achieved as suggested by you
1) Creating location on the OWB Client
2) Samples the files at client
3) Created & Configured external table
4) Copy all flat files on OWB Server
5) Updated the location which I created at the client.
Other way
1) Creating location on the OWB Client
2) Samples the files at client
3) Created & Configured external table
4) Copied flat files on the sever in same drive & directory . like if my all flat files are on C:\data at OWB Client then I copied flat file C:\data on the OWB Server. But this is feasible for Non-Windows.
Hence my problem solved.
Thanks a lot.

Get Exception Information from RFC Response Message

Hi All,
I want to make RFC call from ABAP system to XI RFC Adapter. I found that on the caller side, the RFC has the following interface for RFC exception.
Exception
__Name
__Text
__Message
____ID
____Number
__Attributes
____V1
____V2
____V3
____V4
Can anybody tell me how to get the info contained by this exception structure from RFC caller side (ABAP program)?
Thanks, Jerome

Hi Madan,
My problem is how to display the exception information on the caller side. The called side is able to throw exception now.
Thanks, Jerome

Error 403--Forbidden - From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.

Hi, I have a problem with WebLogic Server: 10.3.5.0.
I need to set that anyone who sees my enterprise application can view the website but not how. I always displays an error.
The error is:
Error 403--Forbidden
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.4 403 Forbidden
The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated.

This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable.
Can you help me?

When I'm working with web servers, and I've not worked with weblogic for quite a while, it has always been rights that have been the gotcha for the 403 error. You need to make sure that if you want everyone to be able to brouse the given folder, you need public read and execute rights on the contents.

Hi ,
This is an indication that ECM cs.ear deployment has failed for some reason . To get the exact reason either check ucm_server1.log or start the server from command line and there the errors will be shown.
Copy the core part and post it .

Get the Error-Message-Number from RFC to SOAP

Hi All,
we have implemented a synchronous SOAP-Call to RFC over XI. How can I get the message-number from the raised exception in the RFC-function Module to the SOAP-Caller?
Thanks a lot
Matthias

Matthias,
For you to have an exception structure when an rfc is imported into Xi, the rfc should have an exception defined. Usually we define an ApplicationError as one of the exceptions.
The idea is that if there was an exception which you didnt handle in your rfc (BAPI return will be emplty), the exception will be returned to XI and shown in SXMB_Moni as hard error(of course there should be a message mapping avaliable in XI )
In all the other cases, since you are populating BAPIReturn which is tables parameter, you should be able see the filled structure in your response message from RFC.

naveen

Hi,
It seems that you are testing this UDF from Test tab. If yes, it wont work.
You need to run the whole scenario.
