Function module with RFC enable

Hello ABAPers,
Im a new comer in ABAP and I would like to have a basic knowledge in RFC using a function module/function group..
I have this project in Travel Dept...I need to connect on a different system using SAP connector...meaning...I will logon to SAP and connect to another system which is VB.net and has a back-end of SQL 2000. After connection I need to select or search a data to that table...for me to get the ticket number.
Before I tried to connect from VB.net to SAP...and successfully used the SAP connector...now I need the vice versa version of this approach..
Can anyone help me? please....
Thanks in advance...Will reward points

For Basic Understanding just look at RFC_READ_TABLE FM,This will give good example
Also Check the SM59 Transaction to create RFC Destination
Please check with below link :

Function Module with RFC for accessing tables

Hello All
I am programming using ABAP in Solution Manager system. I have to take data from tables(T001W and T001K) from a R/3 Server. Is there a function module which extracts data from tables via RFC ?
Thanks
Tharani.

Hi,
Check thes FM's:
RFC_GET_TABLE_ENTRIES
TABLE_ENTRIES_GET_VIA_RFC
GET_TABLE_RFC
or develop a RFC enabled FM to get the required data in R/3 and call it from your program
example :
data: wtab type BDSEL_STAT occurs 0 with header line.
data: tab type BDI_ENTRY occurs 0 with header line.
name = T001W.
CALL FUNCTION 'TABLE_ENTRIES_GET_VIA_RFC'
destination dest
EXPORTING
LANGU = SY-LANGU
TABNAME = name
TABLES
SEL_TAB = wtab
NAMETAB =
TABENTRY = tab
EXCEPTIONS
INTERNAL_ERROR = 1
TABLE_HAS_NO_FIELDS = 2
TABLE_NOT_ACTIV = 3
NOT_AUTHORIZED = 4
OTHERS = 5 .

i have created RFC in this way:
RFC doesn't contain neither import nor export parameters. and i have defined one table in TABLE tab which refers to a ztable created already.
when i imported RFC into XI i came to know that RFC has both Request and Response messages, but i don't need Response message.
Thanks in advance..help would be appreciated

Thankx Michal,
I have written ZRFC this way:
insert ZMM_AUTO_GR from INPUT_TABLE .
if sy-subrc = 0.
commit work.
else.
rollback work.
im not using neither import nor export parameters..but using only tables parameters. but when imported in XI im getting same table structure in both request an response.
please suggest what changes required in above code to invoke my ZRFC in async way.
you will not get any response in XI- what chages required in my code to dnt get .reponse in XI.

Unable to send table to function module using RFC

Hi all,
I'm trying to send a table from XI to a function module using RFC. I tested the process first using indivdual parameters. At this point there were no problems. Now I changed the import parameter of
the FM into a table and imported the changes into XI. I changed the Message mapping and tested it with multiple records. When I run the process XI calls the FM but the FM doesn't receive any data. I tested this by puting a break-point in the FM. There are no errors in the XML Messages Monitor. I found this message in the Communication Channel Monitoring:
Short Log:
Server 0 10_39293 Receiver channel 'CC_BackendIn' for party '', service 'BS_Backend' (internal name 'RfcClient[CC_BackendIn]')
Client data: {jco.client.lang=EN, jco.client.snc_mode=0, jco.client.client=610, jco.client.passwd=******, jco.webas.ignore_jdsr_error=1, jco.client.user=Admin, jco.client.sysnr=10, jco.client.ashost=192.168.51.8}

Current pool size: 0, maximum pool size : 1
Channel History
- OK: 2009-02-18 01:35:14 CET: Message processed for interface MIIA_BapiIn
Any ideas?
Thanks for your help!
Regards,
Ivo van Ee

Hi everyone,
thanks for your prompt response! I tested the mapping in XI and didn't find any error here. So I concentrated on the receiver side. There were some communication channels running on the server that were generating errors. I stopped alle the communication channels and started just the two communication channels for this process. This time the table was successfully exported to the function module! Problem solved. Still not sure what caused the problem in the first place, but everything is working fine now.
Thanks for your help.

Ivo

Difference between BAPI Function Module and Remote Enable Function Module

Dear Experts,
I want to know the main difference between BAPI Function Module and Remote Enable Function Module ?
One main difference that I know is BAPI FM are declared in Methods of Business Object ie BAPI are methods of BOR where as Remote Enabled FM are not. What are other differences? Is it possible to convert a Remote Enable FM to BAPI FM .
regards
Manish

Hello,
Did u create any ZBAPI?
The Procdure for Creating the Customer BAPI is Create a Remote Enabled Function module and then goto the tcode BAPI.
Once u go in to that just take the Project tab and enter the details.
by this way u can create a Customer BAPI.

How to check for a function module with its description and functionality

Hi all,
How to check for a function module,with its description and its functionality,in detail how can I know the purpose of a particular function module,how to search for a function module which suits my requirement .

Hi,
You can search a FM of your requirement by putting in the Key words and searching for a FM. Like * KEYWORD * and then pressing F4.
Say for example you need to search something regarding converstion.
Search for * CONVERT * and press F4.
If there is something specfic like converting date to something you can give
DATE * CONVERT *
OR
CONVERT * DATE * and press F4.
Once you narrow down your search you will have a Function module documentation inside the Function module. Please note that all the FMs willl not have documentation.

Problem in converting a function module in RFC

hi All,
when i m converting a function module in RFC it is showing a error message ,
Generic Types are not allowed in RFC.
How can i handel this.
Regards,
Susheel Joshi

Hi Susheel,
RFC module interface parameters (import, export , tables) can only refer to data dictionary types. Hence if you currently have one of the parameters referring to a type defined in your function group main include or in a type pool, you need to create a SE11 data dictionary structure/ table type for that and then change the data type reference.

How to assign function module with process code in IDOC ?

how to assign function module with process code in IDOC ? and what code i have to write in that function module for custom IDOC ?
helpful answer will be rewarded?

Hi,
First goto transaction we42 -->editing mode --> new entries -->give name of your process code and description --> processing with alv service and function module -->then press enter -->after that enter the name of the function module you want to associate from the drop down and save it.
Thats the way to assign function module with process code.
In that process code we will have the Function modules and Bapi's which will take the data which we are sending through IDOC and then process it.
for example: i am triggering the IDOC for every purchase order created then this process code in the receiver system will take the data which i have enetered in the sender system to create the purchase order and process it and creates the same purchase order in the receiver's system.
Reward if helpful.
with regards,

Creating function modules with step by step

Hi,
plz provide me the material for creating function modules with step by step.

Hi Nagaraju,
Step 1.
GO to transaction SE80.In the drop box list select function group enter your Z Function group name.Press enter it will ask for creating the function group.Create your function group.
OR
In SE37 transaction,in the menu bar Goto - > Function Group - > Create Group.Your Function Group will be created.
Step 2.
Go to transaction SE37.Enter your Z Function module name,your recently created function group name and the description.Press Enter.Now your FM is created.
Step 3.
Enter Export,Import parameters.In the source code tab write the code what you want to write.If any exception write in the exception tab.
Method 2)
First u have to create Function Group.
1.se37->Goto->Function Group--->Create.
2.Create FM.
3.maintain import /export parameters and tables , exceptions.
4.based on the ur requirement u have to bulid ur logic in Source Code by using there Import parameters and u can pass the results by using Export or table.
5.u can raise error by using exception.
Reward if useful.
Thanks

Log on into the function module with different user name.

hi,
        i log on into the system with my user id suppose 'mukka' and i have to check the authorization of another user say 'you' using the function module "authority_check_tcode". but here i am getting the problem that when i assigned sy-uname to 'you' and execute the function module it is entering into the function module with 'mukka' user name only.
sample code:-
                            sy-uname = p_uname.
    CALL FUNCTION 'AUTHORITY_CHECK_TCODE' "#EC"
      EXPORTING
        tcode = v_tcode
      EXCEPTIONS
        ok     = 1
        not_ok = 2.
when i am changing the sy-uname with p_uname the sy-uname is changed but when i entered into the function module authority_check_tcode in the debugging mode at the below the sy-uname variable is showing as 'mukka' only. but i need to check the authorizations of user 'you' pls give me solution to my problem.

Hi,
Why would you want to check the authorisation of another user and not the one currently logged in? The idea of authorisations is to check the current user is able to perform a certain activity. The majority of fields on SYST are constantly updated to have the correct values (partly so you can't fiddel authorisation checks like this
Maybe if you explain to us what you are trying to do we can offer some other help.

I am calling RFC function module from R/3 which exists in BW.
In BW stand alone function module works fine.
When I am Calling from R/3 it is not working,
Can you tell me is it because of the below code, And suggest if any corrections required.
I am calling the call transaction and using EXPORT memory iD inside the program
and IMPORT in after that.
And populating RFC table's table " p_i_tcode_user" finally.
set parameter id 'TCD' field p_tcode.
call transaction 'Z_BW_RSUSR002' AND SKIP FIRST SCREEN.
ENDIF.
get the final user data from submitted program
import gt_users_complete from memory id tcode_userid.
LOOP AT gt_users_complete.
      lwa_tcode_user-tcode = p_tcode.
      lwa_tcode_user-uname = gt_users_complete-Bname.
      APPEND lwa_tcode_user TO p_i_tcode_user.
