Remote Function Call (RFC) within a BAdI in ECC to CRM

I've a remote enabled FM in a CRM system which I want to call within a BAdI implementation of a ECC system. As a result, the CRM system is the RFC server and the ECC system is the RFC client.
The FM in CRM simply gets the relevant rows of a Z table which, of course, only exists in CRM and passes these rows to the calling program as per parameter supplied by the calling program.
Now the BAdI in ECC is for changing 'Contracts' data in SAP (transactional data) before posting the contracts in the ECC database. The business uses a transaction where a large number of contracts are processed and documents posted in the system - and when this happens the system runs through (calls) the BAdI one contract at a time.
If I call the RFC enabled FM anywhere within this BAdI, it gets the data for one contract only so it reduces a great deal of performance in regards to memory consumption, network load etc. So I want to avoid this and call the RFC FM once instead, if possible.
Is it possible to call this RFC FM once only (to load the CRM Z table data for all contracts) and store it in a global table/area within the instantiated BAdI class (visibility public) so that when the BAdI is called the second time onwards it can read the global table/area by READ TABLE WITH KEY statement and avoid the RFC call for each BAdI call?
I was also thinking about may be using ABAP Shared Memory if this is a possibility in order to avoid the repeated RFC call? But this table on the RFC server changes frequently....so it might not be a good idea? or....??
I would greatly appreciate your inputs and thoughts regarding this; it would be great to hear if someone had had a similar experience.
Cheers,
Sougata.

As the Z table is only updated via a particular program in CRM - we developed and called a RFC enabled FM in that report when its updating the Z table to update the Z table in ECC to keep it in sync.
Short term benefit but might be long term pain if the Z table in CRM is updated by another program/process/application in the future! Not to mention any table field changes in CRM has to be also made in ECC everytime which is again a pain.
This is a workaround and definitely not a full-proof solution - but I guess these days one has to shut up and deliver whatever the customer wants!

CATCHABLE EXCEPTIONS in the remote function call (RFC)

Please tell me what are the CATCHABLE EXCEPTIONS in the remote function call (RFC) and to which exception class do they belong????
Thanks in advance.
Dinesh Dhiman

HI,
With external function calls, the EXCEPTIONS addition of the CALL FUNCTION command can be used to assign return values to the exceptions defined in the interface of the called function module. Class-based exceptions cannot be propagated to the caller from a remotely-called function module, and have the effect of an exception that cannot be handled.
As well as the exceptions defined in the interface of the called function module, an external function call can also have the following predefined exceptions:
The SYSTEM_FAILURE exception is the response to a runtime error that occurs when the remotely-called function module is executed.
The COMMUNICATION_FAILURE exception occurs when the connection to the partner system cannot be established or if the connection is lost during communication.
Note
We strongly recommend that you assign a return value to both these exceptions for every RFC, and that you handle this return value, as otherwise a runtime error will occur in the exception situations in question.

Sesh

Remote function call (RFC) for WS_DELIVERY_UPDATE fails w/o error message

Dear Experts,
Iu2019m using WS_DELIVERY_UPDATE to post goods issue against outgoing delivery. SE37 works fine.
RFC call from external program with the same parameters fails without returning any message.
It aborts during call and after that it becomes invalid.
Also calling BAPI_TRANSACTION_COMMIT does not help.
Any idea why SE37 works fine but RFC fails?
Anything I am missing?
Many thanks
Regards
JW

There could be many reasons, I'd suggest to get your Basis admin involved. Take a look at the ABAP dump (ST22), update termination (SM13) or RFC errors (SM58). Although I doubt you'll find something inside SAP, since it seems that RFC call itself fails.
This function is not a BAPI, so BAPI_TRANSACTION_COMMIT won't do any good. All it does is COMMIT WORK actually.

An error occurred when executing a REMOTE FUNCTION CALL.

Dear all,
We have two syetms called DXD and GRD , we have a remote enabled function module in the DXD system , when i am trying to call this Function module from
GRD system it is going for the short dump, and giving the follwing error,
Error analysis
 An error occurred when executing a REMOTE FUNCTION CALL.
 It was logged under the name "RFC_NO_AUTHORITY"
 on the called page.
But i do have the access for the DXD system also, i am really struggling to solve this problem, if any lights are there to help me , i will be thank full for then,
some body suggested for me that we need to maintain the Trusted system tables in the target system.
Thanks & regards
Satya.

first u( user id ) have to get the Authorizations to use RFC ?
object will be like S_RFC or some thing like this.
when u get this kind of error just call /NSU53 then u will come to know which Authorization Object is missing from ur User Profile.

Data error (invalid data type 17) in a Remote Function Call

Hi,
I am passing 2 select-option tables to RFC.
Tables have structures -
   Table1 SIGN(C1)
               OPTION(C2)
               HIGH(C6)
               LOW(C6)
   Table2 SIGN(C1)
               OPTION(C2)
               HIGH(C20)
               LOW(C20)
At the destination side, I have created two table types which have same structure.
But when I call the RFC , program terminates with error - "Data error (invalid data type 17) in a Remote Function Call"
Not able to understand the reason for this error. Please help.
Thanks,
Sujeet

Automatic remote login at remote function call

Hello,
we have three systems, development, testing and productiv. I want to do a remote function call on the repective other system. But I always get a login window where you have to insert your password for that system. Is there a possibility to do this automatically? Thanks.

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.

CALL_FUNCTION_REMOTE_ERROR when calling a remote function call through PI

Hello. Thanks in advance for your perspective on this.
We are developing an interface that runs in an R/3 system and is suppossed to perform a lookup in another R/3 system via a PI 7.0 system.
Here's what we are trying to do, let's call these systems "A", "B", "C" respectively.
R/3 -> PI   -> R/3
The R/3 system (A) executes code, which calls this function module like this:
      CALL FUNCTION 'Z_CHK_MAT' DESTINATION 'XI_RFCADAPTER'
        EXPORTING
          iv_region           = lv_region
          iv_matnr            = ls_matnr-matnr
        IMPORTING
          ev_flg_is_purchased = e_flg_is_purchased.
This code, is set via the "DESTINATION" parameter to use the RFC destination 'XI_RFCADAPTER'. This destination, points to the PI (B) system above.
Anyhow, we're getting a short dump in the R/3 (A) system, which is like this:
CALL_FUNCTION_REMOTE_ERROR
"JCO.Server could not find server function 'Z_CHK_MAT'"
From my analysis, I believe this is because the remote function module Z_CHK_MAT does not exist, in the PI (B) system.
Our developer, believes this should just "pass through" the PI (B) system, and call the function module in the R/3 (C) system.
Any insight on this? In this scenario, does this Function Module need to exist in the PI abap side? Can you give perspective / guidance on this?
Thanks a lot
Steve

No need to exist in PI ABAP side.
Just make sure that:
1. as Michal said, you import it in Integration Repository (and use it in your configurations);
2. the RFC Destination type that points to XI is of type T, not 3;
3. both the RFC Destination & the Sender RFC Adapter (and only them) are using the same Program Id.

Henrique.

Defining Dynamic structure in Remote Function module(RFC)

Team,
I got a requirement, where I need to create a dynamic structure and dynamic table in the exporting tab of Function module(RFC).
Say, I have sales request(4 fields) and sales quotation(5 fields).
Depending on the importing parameter, If it sales request I need to export 4 fields as a structure and if in the importing parameter it is sales quotation then I need to pass 5 fields as a structure.
Any help please??
Thanks,
Sai

Remote function module (RFC)

Hi
In one of the issue, remote enabled FM 'RFC_CALCULATE_TAXES_DOC' is called from SAP
CALL FM 'RFC_CALCULATE_TAXES_DOC' DESTINATION 'ABCD' (ABCD is other system - sabrix)
Can anybody tell me the logic (there is no code in FM) , whether FM with this name is there in other system which is called from SAP, (How processing occurs in case of remote FM).
And how to see what processsing is being done in other system. ?
And why there is no code in this FM in sap?
Thanks and Regards

AS3/BlazeDS remote function calls

We have a pure as3 - no flex - project which connects to server-side Java. The actionscript will, upon interaction from the user, invoke a Java function on the server side, which will then broadcast out a message to all users. This works when testing locally, but when we put the project onto a remote server, the actionscript code will no longer invoke the Java function.
We are unsure as to why this is: the service xml files are the same, and the files are in the correct locations. In the BlazeDS admin console, whenever we try to call that Java function, it is incrementing the InvocationFaultCount variable for the specified destination. Any suggestions why it won't work online, but will on the local machine?
thanks

Hello Case,
The approach in NCo for this purpose is to use RfcCustomDestination, as already recognized by you. Thus you can challenge the user for his personal password and set those credentials for the logon. Best variant is to provide a repository user and password in the configured destination so that metadata is then read with a user that is restricted to metadata lookup permissions only.
In case the infrastructure would issue a token for the logged on user, one could imagine that with such a token and trust between the ABAP system and the NCo application could do some kind of SSO. However, NCo runtime is not prepared so far to allow such a setup.
Best regards,
Markus

Generate Idoc from Remote function call

Hi,
Earlier i have done RFC which is been called with JCO and and sends datastream as well xml.
Now my doubt, is it possiible to generate the idoc for external application through RFC call from JCO?
if so, can anyone send me appropriate links or advice on the subject!
My main concern is i can generate the idoc through RFC call basing on the calling parameters,,, but how to pass the idoc structure for them?
for XML i used Export: E_XML TYPE STRING
for data stream: ITAB LIKE ZSTR_ITAB.
Any inputs will be of great helpfull...

Assigned resultant idoc structure to the Table parameter of type EDIDD in created BAPI.

How to make a dynamic function call from within a package procedure

Hi:
I need to call a function dynamically (name and parameters determined at run time, but return value is known:always an integer). I can build the call and place it in a dynamic sql using dbms_sql. But the function is inside a package and is not public.
So, if I issue:
dbms_sql.parse( cur,'SELECT '||call||' FROM dual', dbms_sql.v7 )
where call is "DOS(234,'V')"
I get:
ORA-00904: "DOS": invalid identifier
If I make the function ("DOS") public and "call" equals "pack.DOS(234,'V')", it works fine, but I don't want to make it public.
Is there a solution?
Thanks in advance
RuBeck

Hi, Kamal:
Calling from outside of the owner package is not possible if it is not public.The calls are from inside the package. It looks like the dynamic select is executed "outside" the package, so the private function is unknown
Make it available in the package headerLooks like it's the only solution
How often this will be executed?This is a library for loading files into tables and executing dynamic validation procedures.
Here's an example of the mechanics:
create or replace package mypack as
function one return number ; -- public function
procedure execute_it( p_name VARCHAR2 ) ;
end ;
create or replace package body mypack as
function one return number is
begin
return 1 ;
end ;
function two( i number, s varchar2 ) return number is -- private function
begin
return 2 ;
end ;
procedure execute_it( p_name VARCHAR2 ) is
select_str VARCHAR2( 1000 ) ;
v_num NUMBER ;
cur NUMBER ;
nf NUMBER ;
begin
select_str := 'SELECT '||p_name||' FROM dual' ;
cur := dbms_sql.open_cursor ;
dbms_sql.parse( cur,select_str,dbms_sql.v7 ) ;
dbms_sql.define_column( cur,1, v_num ) ;
nf := dbms_sql.execute( cur ) ;
IF dbms_sql.fetch_rows( cur ) = 0 THEN
RAISE no_data_found ;
END IF ;
dbms_sql.column_value( cur, 1, v_numero ) ;
dbms_output.put_line( p_name||' returns '||v_num ) ;
dbms_sql.close_cursor( cur ) ;
end ;
end ;
begin
mypack.execute_it( 'mypack.one' ) ; -- Call public function: Works fine
mypack.execute_it( 'two(234,''v'')' ) ; -- Call private function: error 0904
end ;
Thanks for your hints
