Webdynpro/abap portal unable to call Remote functions?? HELP

Scenario:
webdynpro/abap system A talks to system B.
webdynpro Abap has a call as
call function 'BAPI_FLIGHT_GETLIST'
destination 'RFCB'....
At "A"
created SSL Server for https, created certificate request and imported it from SAPtest ticket.
imported certificates for the SSL from "mySAP" and "Server CA" downloaded from sap site
enabled the ACLs for the above 2 certificates on client '000"
The browser's http proxy tool shows that after login to system A with Http, further requests go through RFC destination to system B, called RFCB.
RFCB config to systemB as a specific user, everything is fine.
However, if RFCB is set to 'current user', it does not work.
So, SSO ticket is not used to login to system B, I guess.
How to set up the RFCB. If I change to 'trusted system', I get RFC authentication error. The sdn shows to setup S_RFC auth object into user profice with PFCG.
Can you help?
Thanks.

Hi ,
I have used RFC's couple of time in WebDynpro ABAP .As I am doing WD Application for SRM where I require to fetch data from other R/3 servers .
Now do you want something like this . You will pass some parameters to RFC and based on that will updates data in that Remote R/3 and Also send results that you want show over WebDynpro Application .
Please see thread below .See that help you or not.

What is the exact syntax for calling remote function module.

Hi to all
1.....what is the exact syntax for calling remote function module.?
Thanks and regards,
k.swaminath reddy

hi
good
Lets do simple example where you will first create a RFC in one server (say A) and create normal program in othere server (say B). Finally you will call the RFC in A from B.
Do the following steps for creating RFC in server A.
1. log on to server A
2. go to se37
3. Edit -> function groups-> create function group and give the function group name (say ZGRP).
4. create a FM ( say Z_TEST_RFC) in se37 providing the function group which is created just now.
5. go to attribute tab -> choose remote-enabled module from processing type.
so that your FM will become RFC.
6. provide the import parameter in import tab.
we will provide only two import parameters.
- parameter name : P_NUM1, typing: TYPE, associated type : I & check the pass value (all the parameters of RFC must pass by value).
- parameter name : P_NUM2, typing: TYPE, associated type : I & check the pass value
7. provide the export parameter in export tab.
parameter name : P_SUM, typing: TYPE, associated type : I & check the pass value
8. write the given simple code in source code tab.
FUNCTION Z_TEST_RFC.
P_TOT = P_NUM1 + P_NUM2.
ENDFUNCTION.
Do the following steps for creating ABAP program which will call the RFC in server B.
1. se38 - > creat a program.
2. write the given simple code.
data tot type i.
call function 'Z_TEST_RFC' destination 'XXXXXX'
exporting
p_num1 = 10
p_num2 = 15
importing
p_tot = tot.
write tot.
please note that XXXXXX is RFC connection which is avialable in sm59 transaction in server A.
-go to sm59 - > abap connection (list of RFC connection configurations are avialable). choose server B connection and replace it of XXXXXX in the code.
finally you can execute the normal abap program that will call the RFC and display the result.
reward point if helpful.
thanks

Calling Remote Functions Locally Triggers any Database commit(Implicit)

Hello,
Am making use of RFC enabled function module as normal function module (Calling remote function module locally).
My question is does it trigger any implicit database commit or not. Since synchronous RFC triggers database commit.
Regards,
Tenzin Choegyen

Since synchronous RFC triggers database commit.
Let me correct the statement both synchronous as well as asynchronous RFCs trigger an implicit DB commit.
SAP documentation on synch-RFCs states:
If the content of dest is equal to the constant space, then the addition DESTINATION is ignored and a normal call CALL FUNCTION func is executed.
Please note that you should not use the DESTINATION addition or use DESTINATION space. DESTINATION none will start the FM as an RFC in the same app server.

Webdynpro ABAP/Portal. Plugin HTTP connection issue on WaitingEventQueue.js

Hello,
We are experiencing a strange Portal Behavior with our Webdynpros. Our portal contains several iViews including some Webdynpro (ABAP) and some reporting transaction calls that use SAPgui for HTML.
When portal is called for the first time and a user logs in, two connections of type RFC can be seen for that user in SM04 in our ERP system. All iViews work as expected. For example, calling the Time Management webdynpro closes one of the RFC connections and starts a new Pluguin HTTP connection. We can go back and forth between the welcome page and this Webdynpro with no issues.
If we then select one of the reporting transaction codes, the portal launches the SAPGUI for HTML. Report retrieves and shows data, and then we close using the "Exit" button provided by the sapgui for HTML
Next we try again to launch any webdynpro (abap), but SM04 shows that the new Plugin HTTP session gets stuck and spinning mid way, and will stay there. Refreshing the Portal screen with F8, navigating back and forth, logging off and on again has no effect. The webdynpros will not launch again. Only webdynpros are affected, any of the reporting transactions can be called successfully over and over.
We have figured that deleting Temporary Internet files (we are using IE 7), and in particular by just deleting the WaitingEventQueue.js?XXXXXXXXXXX file, the system will break away from the spin loop and show the webdynpro again, but eventually it will get stuck again, and asking the users to delete their Temporary Internet Files every 5 minutes is not a workable solution
I have reviewed the contents of this javascript file at different points during the test, and the contents do not change, so deleting the file and the recreate process must be resetting somehow the queue and allowing for a new correct communication.
Is there a way to properly reset this event queue (for example from ABAP, when the webdynpros are reloaded) in order to avoid the spin loop?
Thanks for any help!
Andres

Well, we got the issue resolved, so here is what we did, in case anybody is interested:
Tested again our portal with multiple versions of Internet Explorer, in particular IE8 and IE6, the Webdynpro behavior was normal (no timeouts or locks). It even worked when we installed IE7 in a brand new machine and tried our portal.
So we started suspecting if maybe the particular IE7 that we install internally (with specific settings and policies) may be the culprit. We took a desktop that was producing the timeouts and used the following options in IE7:
Tools->Internet Options->Advanced(tab)-Reset Internet Explorer settings
and, voila! the next time we ran there, the portal did not create any timeouts.
We even asked our desktop support team to uninstall and reinstall IE7 in the same machine after we did the reset, and even after the re-install that the timeout problems did not re-appear.
One of the things that the "reset" option does is delete the Add-ons used by IE.
So as a last test, we took a machine that was presenting the problem and went to the Internet Options to disable all the add-ons (in the Programs Tab). The error disappeared.
And even after enabling back all the add-ons, the error would not return.
Conclusion:
Without being able to pinpoint the specific add-on (or combination) that causes the problem, we suspect that some of them conflicted, causing IE7 to behave abnormally. Disabling them all, restarting Internet Explorer, and enabling them again, makes the WaitingEventQueue.js work as it should

Local function calling remote function - error

Dear All
i have following remote function wich return some value from both methods ie.
1) select func1(variable, varialbe) from dual@remoteDB; working
2) select func1(variable, varialbe) from dual; -- by making a synonym at local
Now i create a local function funclocal calling remote functino i.e. func1 in this example as:
CREATE OR REPLACE FUNCTION funclocal(locc varchar2, artnoo number)
RETURN NUMBER IS
query_str VARCHAR2(1000);
STKQTYY NUMBER;
artno number(10);
loc varchar2(80);
BEGIN
artno := artnoo;
loc := locc;
query_str := 'select func1(loc, artno) from dual ';
EXECUTE IMMEDIATE query_str
INTO STKQTYY;
RETURN STKQTYY;
END;
compiled successfully.
But when i run as:
SQL> select funclocal('abc', 469183) from dual;
select funclocal('@st3', 469183) from dual
ERROR at line 1:
ORA-00904: "ARTNO": invalid identifier
ORA-06512: at "funclocal", line 11
Please guide me.
Regards
Saeed

EXECUTE IMMEDIATE query_strAs Andreas states: Why are you using dynamic sql?
From what I see all you need is sth like
create or replace function funclocal (locc varchar2, artnoo number)
return number
is
begin
return func1 (locc, artnoo);
end funclocal ;
/even the whole concept of a »local« function seems suspicious. Why do you need that one?

Unable to call local function in select statement.

Hi all,
I am unable to call the local function in select statement in below scenario.
DECLARE
l_cnt NUMBER;
FUNCTION FUN1 RETURN NUMBER
AS
BEGIN RETURN 2;
END;
BEGIN
SELECT FUN1 INTO l_cnt FROM DUAL;
DBMS_OUTPUT.PUT_LINE(l_cnt );
END;
/Any alternate way to call local function in select statement?
Thanks
Ram.

Hi,
Sorry, you can't call a locally defined function in a SQL statement, even if that SQL statement is in a PL/SQL block where the function is in scope.
This applies to packages, also. If a function is not declared in the package spec, but only in the package body, then you can't call it from SQL statements in the package body.
Why do you want a locally defined function? Why not a function defined outside the procedure?

Calling Remote function tool leads always to a logon screen

Hello,
I run an remote function tool in system A. In System B I run a report calling this function module.
Each time, I execute the report, a remote logon screen appears. It looks the same like the one you logon the system. You have to specifiy client, user and password.
I know one possibilty to avoid this logon screen appeaering.
System B (holding the function module) must declare System A as a trusted system. Thus, the user does not need to logon system B, each time calling the func. module. I processed this in correspondence with the help data, but the screen still appears.
Is there any other possibilty to avoid appearing the logon screen or does anybody know wheter I did something wring??
thanks, holger

Hi Holger,
1. This has to do with tcode SM59 (Maintain RFC Connections)
THE CALLING SYSTEM HAS NOT DEFINED
USER ID / PASSWORD TO LOGON TO THE TARGET SYSTEM.
HENCE, IT SHOWS BLANK LOGIN SCREEN
2. Under the node RFC Destinations ---> R/3 Connections,
various systems are defined for RFC Purpose.
3. Lets say ur system(which u want to connect) is PRD.
4. Double Click PRD and go the the details.
5. There are 3 Tabs. Goto LOGON/SECURITY TAB.
6. In the logon information , enter the
USERID and password and client.
7. Save.
Then try your program.
Hope this helps.

Amit Mittal.

Urgent: No data while calling remote function in custom widget.

Hi,
I created a function module with transaction se37 and in its attributes checked the 'Remote Enabled' radiobutton.
Now in my widget I called this remote function in my RFC view.
The data is not displayed in the widget and in debug mode error is displayed :
"Type error: data.root has no properties (RFCRequest .js: Line 102 )"
what is the reason for the error ?
or am I going wrong with remote function module call.

Problem: Unable to call a function in parent swf from the child swf.

I am working on a site right now that has a parent loader
(all it contains are the menu bar [which is as3 tweened] and the
functions for calling all of the other pages.) The problem that I
am having right now, are some of the internal or child pages, need
to call functions that are in the parent loader. For what ever
reason, I am unable to do any of that.
I have attached the code so you can look at that.
Let me see if I can explain it any better.
The code I just posted is for the Main Stage swf called
loader.swf. It has the menu, and all the functions that control the
menu's movement and when to load all the other swfs. The easiest
way for me to ask this, is to show you.
click
http://dev.locallinux.com/mystictan/layout2.html
When you get there, you will see the menu bar, and it is
loading home.swf onto the stage behind the menu.
Mouse over "The Perfect Tan" and click on "1: Base"
You will notice it just loaded a new swf called ptbase.swf.
Well in that swf is a button for "Products" That button
basically needs to take you to "Products > 1: Base" on the menu
(not working yet, I know. But theres no point in me making that,
until I could get this working"
What I would like is when you click on "Products" in
ptbase.swf, it calls the function clickedProductsBase(), which does
its thing. But that function is back in the loader.swf. Does that
make sence?
What am I missing here?

RyanORo, thank you very much for your response.
I try that, and I get this sort of error when I click on it:
TypeError: Error #1006: fwd is not a function.
at ptbase_fla::MainTimeline/testing()
I know all that code that I posted was a bith much, but here
is the movie loading part:
function loadComplete(event:Event):void
loaderbar.visible = false;
mainbody.removeChild(thisMC);
thisMC = MovieClip(myloader.content);
myloader.unload();
mainbody.addChild(thisMC);
thisMC.gotoAndStop(1);
TransitionManager.start(thisMC, {type:Fade,
direction:Transition.IN, duration:5, easing:Strong.easeOut});
mainbody is an empty mc under the menu, so that the loaded
swf file appears under the menu.
You know what, scratch all that . *MOOWHA* I could KISS you
right now. "(parent as MovieClip).clickedProductsBase()" did not
work because it was calling it out of the wrong parent. Just did
"(this.parent.parent as MovieClip).clickedProductsBase()" and that
did the magic I needed. Thanks...

WebDynpro ABAP Portal Integration

Hello,
i want to integrate a WebDynpro ABAP application from ERP 200 in the portal.
There are several system aliasesdefinded in the portal.
Anybody knows which system should be used to get a connection to the ERP 200 of the discovery system?

Hi Andy,
You have to setup your SSO such as User Mapping in your Personalization -> Profiles at Portal.
There are other methods, please visit help.sap.com for more information.

Call remote function on a satellite system using RFC target sys option

Hi all,
I am on the Java stack and I would like to call the ABAP stack of a statellite system. I can create a JCo connection on this system directly but for security reason I am not allowed to do that. I would like to call this system through the ABAP stack of my machine (I am in dual stack environment).
- How can I use RFC target sys (available in SE37 for Remote-Enabled functions) with my JCo connection?
- Or, is there a generic function which can call all other functions on a remote system (still using RFC target sys)?
Many thanks,
Stephan

Siddhesh - thank you for the link; the blogs by Thomas are required reading as far as I am concerned.
Hi Raja;
 do you mean another ABAP system (was6.40)?
and from here using another FM you call the 4.6c
system RFC ?
Yes, that is what we are doing. We are calling a web service from an Intranet form to the 6.40 system that, in turn will call the 4.6C system and pass the data back to the Intranet form (through 6.40)
 may be you could pass the RFC destination as import
parameter to the 6.40 RFC and use the same will the
call to 4.6C RFC from the 6.40 RFC
That would work, but it would be more beneficial to just use the function module on the 6.40 system as a proxy to the function on 4.6c and not have to enter code in it each time.
I had thought of writing just one function module in the 6.40 system that could dynamically call any different function module in 4.6c (based on the input parameters), but since were are trying to accomplish SOA, we need visiblity to each web service (ergo function module).
If it's not possible, that is OK I am just hoping someone had found a way to pull this off.
Thanks!
John

Call Remote Function Module with SAEURI dataelement as Export parameter

Hi Experts, Am creating a program in a Gateway system, where i need to call a FM from HR system.
My Code is like this,
Data: lname(20) type c,
lv_url type SEAURI.
Call 'Z_EMP_GET' Destination 'HR_DEST'
Exporting
Pernr = '12345678'
Importing
lname = lv_lname
Url = lv_url.
At HR Destination system, I have a FM 'Z_EMP_GET ' with signature as
Importing : Pernr Type NUMC
Exporting : lname Type Char20
Url Type SAEURI(Char 4096).
When i debugged it, I see the Remote FM is getting Perner value and returning only lname, but URL paramter is empty.
I believe i have problem in receiving Long Text (URL - Char 4096).
How can i handle this and let me know if need to specify String length parameter for RFC call somewhere.
Also let me know if need more details
Thanks in advance.
Thanks in advance.

Hi naveenraj,
I don't know which type of URL you want in output but you can check entries in table HTTPURLLOC and or if you want URL of employee photo then you have to use this FM HRWPC_RFC_EP_READ_PHOTO_URI.

The webdynpro/ABAP (WDA) calling RFC enabled FM of other ECC systems

The webdynpro/ABAP (WDA) has problem calling RFC enabled FM of other ECC systems.
WDA expects all the ABAPs, RFC FMs of remote system(DEV, QA..) to reside inside its own instance.
It is hard to transport and maintain these ABAPs FMs into a portal ABAP WDA instance.
Proxy generation at WDA client:
=======================
1. If we can make an XI enable an ABAP or RFC enabled FM of the remote ECC,
I think the XI proxy classes can be generated at the client WDA system.
Other options?
How do I do it? Can you give some tips.
2. How do I manually code the RFC Call to BAPI/FM from Webdynpro controller or other interface?
I am stuck with the above as the webservice option is not available at our ECC server. It does not have a java engine installed for webservice to be available.
Can you help on the above 2 options?

Hi Mike ,
 Answer of 2.
How do I manually code the RFC Call to BAPI/FM from Webdynpro controller or other interface?
I am doing same thing for my current SRM implementation.I am taking data to SRM server from another R/3 server .
This is solution I have used
1) First of all I have made ABAP connection in SM59 .
Go to SM59 .In ABAP Connection creat ABAP connection with system with which u want communicate .
Eg I am connection with Systems PB1.
So i developed Connection call PB1CLNT800.
2) In my requirement I have taken data in my context from another r/3,
I have give called RFC in my supply function of node.
Call to RFC is as usual.
In my case,
CALL FUNCTION 'RFC_MATNR'
DESTINATION 'PB1CLNT800'
TABLES
IT_MATNR = IT_MATNR.
Onwards I have read my itab IT_MATNR and populated data to context.
Hope solution will serve your purpose.
Give point if it works .If any problem i have other ways.
