RFC function module - to have it as time dependent

Hi,
I have a RFC call to CRM system from R/3 side. This call is made to get email address of users in CRM system - during the triggering of order confirmation output.
Some times the RFC queue is full and these calls also get in to the queue blocking the queue. This call for me it is an optional and it should not get struck in the queue meaning the order output process should not wait for longer time.
Is there a way that I can say if the call is taking longer time say over 60 seconds no need to wait for the CRM data. Is there any option in the function module to do so (something similar to "starting new task", "performing <a routine> on end of task").
Thanks in advance...
Krish

Thanks for your responses.
May I know where I can set the timeout in SM59? If it is a common setting for all RFC connections, then I cannot touch since the regular calls to CRM/ other systems shouldn't get affected. If it is specific to the RFC connection then I can create a new one and use it over here with time out setting.
Asynchronous RFC I can try but this call to CRM system is made from the output routine - so I am not sure how we can use it over here. The output routine checks if any valid email address found in CRM system for the customer. If so then it sets sy-subrc = 0. Since this routine is called during the order creation the wait causes delay in order getting saved. This happens occasionally when the CRM queue is fully occupied.
Thanks,

RFC function module without RETURN parameter thows error in XI. Please help

Hi Experts,
I have a File to RFC scenario in XI. The RFC function module that I am using at the receiving end does not have "RETURN" parameter. So when I test my scenario I get "RETURN" parameter not found error on SXMB_MONI.
So is it mandatory that RFC function module must have RETURN parameter when used in XI?
Is there any work around to avoid the error without changing the RFC function module?
Please help!
Thanks
Gopal

In my senario the QOS is best effort because it is a Sync.
But the function module is sync in nature as it is returning a parameter called SO_Docs and Ret_Msg. The Ret_Msg contains the error info but it not of BAPIRET2 type.
So is there any way to avoid this error when my QOS is best effort?
Please help!

Call RFC Function Module and return 1000 records at a time

I would like to call a Remote Enabled Function Module from a non SAP system. This function module will select data from the database and return it to the calling program.
Suppose there are 100,000 records that need to be returned, but the calling module would like the data in chunks of 1000 records. Therefore the calling program would call the FM 100 times.
How do I code the function module to know on each subsequent call to grab the next chunk of 1000 records?
Let me know if additional information is needed.
Thanks,
Aaron

Hello,
Here is how you can go for this issue:
1. Create one RFC function module with following parameter. These parameters are with respective of chunking logic.
     Import: Package Size
     Export: Total number of records
     Changing: chunk count
Implement following logic:
1. First of you need to know how many chunks you need to fetch for that get the count of total number of records. This is one
    time activity so you better maintain one flag import parameter will be set to 'X' only first call.
2. Get the number of chunk using total number of records / chunk size for e.g. 1000 / 100 so chunk count = 10.
3. Define internal chunk counter in function module which will be used to locate the correct chunk depending on the chunk
    counter value sent from calling program.
4. Send first call with package size 100 and chunk count = 1, execute select statement and increment internal
    chunk count check if chunk count = internal chunk count in current case chunk count = 1 so exit select statement and return
    with first chunk.
5. Send second call with package size 100 and chunk count = 2. Execute select statement and check chunk count with internal
    chunk counter, in current case it will be 1 so skip that data and go for next chunk of 100 records increment internal chunk
    counter. In this case it will match with external chunk count = 2. load output table with that data and return to calling program.
6. Repeat step 4 until you reach last chunk.
You need to use SELECT...ENDSELECT with PACKAGE SIZE addition so for every loop it will return number of records mentioned in package size.
Hope this helps.
Thanks,
Augustin.

What are the steps we have to follow to develop RFC function module

hi
what are the steps we have to follow to develop RFC function module

I will tell you simple example within r/3 systems..
source system - A (SAP R/3 )
Destination System B (SAP R/3).
First create RFC Destination in SM59 - in A System.
Createing RFC Destination - GOTO SM59 Transaction and click R/3 System .
it will go second screen and give ur RFC Name ,IP Address and log on details.
click on test concetion and remote logon.
now create RFC Function module in B System.
goto se37 - create fm with starting with Z* or Y*.
maintain all data like
attribute should be remote enabled
importing is v_matnr
exporting is v_maktx.
write the simple code - select single maktx from makt into v_maktx
where matnr = v_matnr.
Call this fm in report program in se38 in B sytem and copy the FM.
paste this code A System
use ur logic and destination 'RFC Name'.
Reward Points if it is helpful
Thanks

Problem while calling an RFC Function Module in Background

Hello,
I have created a RFC function module for reading data from an external DB system. The FM calls an external RFC program (coded in C++ using RFC SDK), which delivers the required data. This external program is maintainged as an TCP RFC Connection in SM59.
Further I have created a report, that calls the RFC function module to get the data from the external RFC programm.
My problem is, when I call the report in foreground, everything works OK, the RFC connection works and data can be read from the external program.
However, when I schedule the report to run in background as a job, the report is stating in the protocoll that there was a problem calling the defined RFC connection (although the connection is working properly at that time).
More funny is, this particular problem with running in background occurs only in the productive system, in test and development system the report works correctly also while running as a job in background.
Can you suggest the solution to this problem? Could it be something with authorisations or server settings?
I will be on holiday for the next 6 weeks, so take your time to answer .
Regards,
Dusan.

This is an external RFC server program, not a remote enabled ABAP RFC function module as the others seem to be assuming, right?
Is it possible that your DEV and QAS systems only have one application server, but the PROD has many and dedicated one(s) for processing low priority background jobs?
It might be that the target server of your TCP connection is not this BTC instance, and your RFC server is returning the data "locally" - so, into nirvana...
Just guessing, but might be worth checking.

Backgroung job failing becuase RFC function module is running in Dialog

Hi,
I have a program which is calling a RFC function module. I am running this program in background as a job. Now this function module which is in other system is running in Dialog and giving a time out error and the job is failing becuase of that.
I tried call fucntion 'test' in background task
destination 'XVZ'
tables
test = 'test'.
But this is not working, i can still see this function module running in Dialog in SM50. Any suggestion?
Thanks,
Shweta

Hi !
RFC-Called function-modules are running in a dialog workprocess of the
target system (they could not run in a batch proecess !!).
That means the do have the same "Timeout" limitations than any other
Dialog-Process.
What you can do:
- The Dialog "Timeout" could ce increased by your SAP-BASIS
- If they could not - you should "shorten" the LUWs in the target-funktion.
...means - put a COMMIT WORK an any point the work is done.
After a COMMIT WORK the "Timeout" Counter beginns at 0 !
Hope that helped....
Reward points would be nice...

RFC Function Module behaves differently in foreground and background

Hi,
I have RFC function module which works well when executed in debugg mode where as in normal mode it doesnt work as the time stamp is not changed and the record cannot be created with the same timestamp.
Can anybody suggest any solution on how to change the current timestamp when still in the same LUW.
Regards,
Roberts.

Hi,
Use:
T1 = SY-UZEIT.
GET TIME.
T2 = SY-UZEIT.
T1 will be different from T2

RFC Function module is not working in program while Background

Hi All,
we have a one program in BI system which is calling RFC function module. it is executing the program in foreground very well. Same program we have executed in background , it is not working at all. Thiis RFC function module exists in R/3 4.6c system.

Hello Raju,
Transactional call of a remote-capable function module specified in func using the RFC interface. You can use the addition DESTINATION to specify an individual destination in dest. If the destination has not been specified, the destination NONE is used implicitly. Character-type data objects are expected for func and dest.
When the transactional call is made, the name of the called function, together with the destination and the actual parameters given in parameter list, are registered for the current SAP LUW in the database tables ARFCSSTATE and ARFCSDATA of the current SAP system under a unique transaction ID (abbreviated as TID, stored in a structure of type ARFCTID from the ABAP Dictionary, view using transaction SM58). Following this registration, the program making the call is continued by way of the statement CALL FUNCTION.
When executing the COMMIT WORK statement, the function modules registered for the current SAP LUW are started in the sequence in which they were registered. The statement ROLLBACK WORKdeletes all previous registrations of the current SAP LUW.
If the specified destination is not available for COMMIT WORK, an executable called RSARFCSE is started in the background. This attempts to start the functional modules registered for an SAP LUW in their destination, every 15 minutes up to a total of 30 times. You can make changes to these parameters using transaction SM59. If the destination does not become available within the given time, this is noted in the database table ARFCSDATA as a CPICERR entry. By default, this entry in database table ARFCSSTATE is deleted after 8 days.

Regarding RFC function module

Hi ,
Our requirement is like this , we have to send the material long text from r/3 to srm system
for this we have developed a rfc function module with srm system as destination .But when we are using this in the program while rfc funtion module is invoked that time it is going to srm system and asking for credentials. how can i supress this .
Thanks in advance.

Hello;
In your RFC destination, you can use a default user.
If you want to use the current user, go check

Hi Shree,
   Can you explain it bit more?
   Do I have to call the function module with "IN BACKGROUND TASK"?
   Or is it that I have to just put external breakpoint in the function module?

Problem with RFC function module from R/3 to CRM

Hi, i have a RFC function module created in R/3, this is the code:
function Z_CRM_PRODUCTO_INTERLOCUTOR.
""Interfase local
*" IMPORTING
*"     VALUE(GV_VKORG) TYPE VKORG
*"     VALUE(GV_VTWEG) TYPE VTWEG
*"     VALUE(GV_MATNR) TYPE MATNR
*"     VALUE(GV_KUNNR) TYPE KUNNR_V
*" EXPORTING
*"     VALUE(GV_KDMAT) TYPE MATNR_KU
*"     VALUE(GV_POSTX) TYPE KDPTX
*" EXCEPTIONS
*"      NOT_FOUND
UNPACK GV_MATNR TO GV_MATNR.
UNPACK GV_KUNNR TO GV_KUNNR.
select single KDMAT POSTX
          into (GV_KDMAT, GV_POSTX) from KNMT
          where   VKORG = GV_VKORG
                  and VTWEG = GV_VTWEG
                  and KUNNR = GV_KUNNR
                  and MATNR = GV_MATNR.
IF sy-subrc <> 0.
    RAISE NOT_FOUND.
ENDIF.
endfunction.
When i call this function from CRM, i do it like this:
CALL FUNCTION 'Z_CRM_PRODUCTO_INTERLOCUTOR'
DESTINATION LV_RFCDEST
EXPORTING
    GV_VKORG = lv_vkorg
    GV_VTWEG = ORGMAN_H-DIS_CHANNEL
    GV_MATNR = ORDERADM_I_WRK-ORDERED_PROD
    GV_KUNNR = WA_DATOS_PER-N_PAGADOR
IMPORTING
    GV_POSTX = IT_POS_LINE-DESCRIPCION
    GV_KDMAT = IT_POS_LINE-material
EXCEPTIONS
    not_found = 1.
where:
it_pos_line-descripcion type string
it_pos_line-material type string.
Well, my problem is that when debugging, in R/3 the 2 return values have the correct value, but when they are passed to CRM they have only one position.
As i've been told, it was working ok, but it's being wrong since we made a ¿conversion to unicode?. Maybe I should change the type of return ???
Thanks in advance !!!

Hello Maria,
Make sure you define your parameters in CRM exactly the same way as in R3, do not use type string here.
So:
it_pos_line-descripcion type C char 40,
it_pos_line-material type C length 35.
Kind regards,
John.

Calling a RFC Function Module

Hello Guys,
I have a question regarding calling a RFC function module.
In BW - BI 7.0 I call a RFC function module:
(The ABAP program in BW-BI 7.0 is below)
CALL FUNCTION ''ZTESTFUNCTIONMODULE' " Function module in ECC
     DESTINATION 'DECCLNT110' " ECC system
    TABLES
      it_gl_item   = it_gl
      it_errlog_gl = it_errlog_gl.
The 'ZTESTFUNCTIONMODULE'   is RFC enabled in the ECC system.
The purpose is we retarct the data from BW to ECC.
When I run the function module it always asks for the user id and password.
The SAP logon screen appears and it asks for the user id and password.
The destination is maintained in the SM59 transaction and also the user is maintained there. I think it should login automatically into remote system and return the tables. is it correct. How to skip the logon screen.
Do I have to pass the user id and password in the function module. I think it should take the user id from the SM59 destination. Is it correct.
Please advise. As always thanks for your help guys.

Hi Senthil,
I think you answered your query in your question itself
The user ID and password need to be maintained in RFC destination in SM59.
Go to SM59 and then click on test connection..if it does not ask for ID and passwoed that means correct ID and password is maintained in SM59 otherwise maintain it.

Atish

Get interface of RFC function modules in a remote system

Hi,
my goal is to write a report which checks if DDIC structures in two systems fit together when I use RFC`s.
I have the destination and the name of the RFC.
Can somebody tell me if I can get a list of the Importing/Exporting Parameters of this RFC? Maybe even with a typedescribtion?
Thanks for you help.
Best regards
