Want to transfer data via idocs from one R/3 to different R/3

Question

Hi!!
May i hav nay step by step pdf which gives the complete flow of how to transfer idocs from from one  R/3 to different R/3.
Though i have the basics steps but some where I m stuck.
Also I have two doubts::
1.Is thr Any relation bw port name and Logical System name?Can they be same.??I  hav kept Logical System name as SAPE60 AND PORT name also as SAPE60(in e60) and  SAPEI6(in ei6) servers respectively.
2.Should the Logical System names be maintained same in both the servers??
Kindly respond .
Helpful answers will be rewarded points!!!

Answer 1

Hi Deepika ,
See the Example scenarios
MASTER DATA TRANSFERMATION BETWEEN 2 DIFF CLIENTS
•     For this scenario Client 800 is the Sender and 810 is the receiving system
1. Creating Logical Systems
o     Login using 800 client
o     Go to T. Code SALE
o     Expand Sending and Receiving Systems
o     Expand Logical Systems
o     Click on Define Logical System
o     Click on New Entries
o     Create STUD_S, STUD_R Logical Systems
o     Save and come back
o     Assign the STUD_S Logical System to client 800
o     Assign the STUD_R Logical System to client 810
2. Creating the RFCs
o     Go to T. Code SM59
o     Expand R/3 Connections
o     Enter RFC Name as STUD_S
o     Connection Type as 3
o     Language as EN
o     Client as 800
o     User as  SAPUSER
o     PWD as abap
o     Target host as sap
o     Click on Remote logon button to test the RFC
o     Enter RFC Name as STUD_R
o     Connection Type as 3
o     Language as EN
o     Client as 800
o     User as  SATISH
o     PWD as abap
o     Target host as sap
o     Click on Remote logon button to test the RFC
3. Creating the Message Type
o     Go to T. Code WE81
o     Click on change, continue
o     Click on New Entries button
o     Give message type as ZBAPI_STUD_MAS and description
o     Save and back
4. Creating the Segment
o     Go to T. Code WE31
o     Give segment name as ZBAPI_STUD_SEG
o     Enter Short Text
o     Enter the Field Name and Data Element in the text boxes
o     Save, continue,
o     Click on Edit -> Set Release.
5. Creating the Basic IDOC Object
o     Go to T. code WE30
o     Give obj. name as ZBAPI_STUD_IDOC
o     Click on create
o     Select create new radio button, give description and continue
o     Select the IDOC obj name and click on create button
o     Enter the segment name which is create earlier
o     Select the check box if you want to make the segment mandatory
o     Enter 1 in minimum number 99999 in maximum number, continue
o     Save and back
o     Click on Edit -> Set Release
6. Creating Customer Distribution Model
o     Go to T. Code BD64
o     Click on change and Create model view button
o     Enter the short text and Technical name as ZSTUDENT
o     Select the model and click on Add Message Type Button
o     Give the Sender as STUD_S,
o                    Receiver as STUD_R,
o                    Message Type as ZBAPI_STUD_MAS
o     Select the model view & click on Environment -> Generate Partner Profiles
o     Select Transfer IDOC Immediately and Trigger Immediately radio buttons
o     Click on Execute
o     You should get a list in green color which means it executed successfully.
o     Back to main screen, select the model view
o     Click Edit->Model view->Distribute
o     Click on continue
o     You should get a list saying model view is distributed successfully.
7. Checking the Port
o     Go to T. Code WE21
o     Expand Transactional RFC
o     Find the port from the list which is created using BD64 for STUD_R (Receiving system) RFC Destination.
8. Checking the Partner Profiles.
o     Go to T. Code WE20
o     Expand Partner Type LS
o     Select the Partner profile STUD_R
o     Double click on Message Type ZBAPI_STUD_MAS in Outbound parmtrs.
o     Check Receiver Port is assigned correctly
o     Check the Basic type as your Basic IDOC object.
9. Assigning the Message Type to Basic IDOC Object
o     Go to T. Code WE82
o     Click on Change & continue, New Entries button
o     Give the Message type as ZBAPI_STUD_MAS
o     Give Basic Type as ZBAPI_STUD_IDOC
o     Release as 46C
o     Save and back
10. Creating Inbound Function Module (Posting Program)
o     Go to T. Code SE37
o     Create a function Module IDOC_INPUT_ZBAPI_STUD_MAS
o     Set the Processing type as Remote Enabled Module and mode as start immed, in Attributes Tab.
o     Import Parameters
INPUT_METHOD                 LIKE     BDWFAP_PAR-INPUTMETHD
MASS_PROCESSING     LIKE     BDWFAP_PAR-MASS_PROC
NO_APPLICATION_LOG     LIKE     SY-DATAR
MASSSAVEINFOS                 LIKE     MASSSAVINF
o     Export Parameters
WORKFLOW_RESULT          LIKE     BDWF_PARAM-RESULT
APPLICATION_VARIABLE     LIKE     BDWF_PARAM-APPL_VAR
IN_UPDATE_TASK          LIKE     BDWFAP_PAR-UPDATETASK
CALL_TRANSACTION_DONE  LIKE     BDWFAP_PAR-CALLTRANS
o     Tables
IDOC_CONTRL     LIKE     EDIDC
IDOC_DATA          LIKE     EDIDD
IDOC_STATUS     LIKE     BDIDOCSTAT
RETURN_VARIABLES     LIKE     BDWFRETVAR
SERIALIZATION_INFO     LIKE     BDI_SER
o     Exceptions
