In the previous part we created an IDoc structure which can carry our data from source system to target system(s). In this part we will understand how to setup the source system to be able to generate and send an outbound IDoc.

In the previous part we created an IDoc structure which can carry our data from source system to target system(s). In this part we will understand how to setup the source system to be able to generate and send an outbound IDoc.

Outbound Settings

Define Logical Systems and Assign Client to Logical System – Transaction SALE

Transaction SALE

  • Go to Define Logical System (See the figure)
  • Define a new logical system to identify the local system and save it
  • Now, go to Assign Client to Logical System (See the figure)
  • Add a new entry
  • Specify the client, previously created logical system and other attributes
  • Save the entry
  • Define a new logical system to identify the partner system and save it

Maintain RFC Destinations – Transaction SM59

  • Create a new RFC destination for R/3 type connection
  • Specify the target host on Technical settings tab
  • Provide the Logon credentials on the Logon/Security tab
  • Save the settings
  • To verify the settings, Click on Test connection or Remote logon

Define Ports – Transaction WE21

  • We need to define a tRFC port for the partner system
  • Click on Transactional RFC node
  • Create a new port
  • Provide a description
  • Specify the name of the target RFC destination
  • Save the object

Maintain Distribution Model – Transaction BD64

  • Click on Change
  • Create a new model view
  • Provide a Short text and Technical name to the model view
  • Add message type
  • Specify sender and receiver systems
  • Also, specify the message type that we created previously
  • Save the Distribution model

Generate/Create Partner Profile – Transactions BD82/WE20

Transaction WE20

  • To generate Partner profiles automatically you may use BD82 or go to BD64 and use the menu path Environment -> Generate partner profiles
    • Otherwise, you may use transaction WE20 to create a partner profile
  • On selection screen, specify the model view, target system and execute
  • The result log will be displayed on the next screen
  • To verify the partner profile go to WE20
  • Check the partner profile for the target system

Distribute Model View – Transaction BD64

  • Select the Model View
  • Go to menu path Edit -> Model View -> Distribute
  • Result log will be displayed on the next screen

Outbound IDoc Generation Program

Create an executable program ZRZ_ORDER_IDOC in SE38. Below, I have described the program logic:

  • Fetch the data from the DDic tables ZCUSTOMERS, ZSOHEADERS and ZSOITEMS as per the selection criteria
  • Fill the control record structure of type EDIDC
    • Specify message type, Basic IDoc type, tRFC Port, Partner number and Partner type of the receiver
  • Fill the data records
    • Define structures like the IDoc segments
    • Fill the structures with fetched data
    • Pass the segment name and the above structure to the appropriate fields of EDIDD type structure
    • Append the EDIDD structure to the EDIDD type internal table
  • Now, call the function module MASTER_IDOC_DISTRIBUTE and pass the IDoc control record structure and data record table
  • Commit work if return code is zero
  • Function module returns a table of type EDIDC to provide the details about generated IDoc
  • Display appropriate log

You can download sample code for the above program here.

Thus we have completed sender side configuration required for ALE. In the next part we will see how to configure the receiving system to be able to receive and post the inbound IDoc.

    Hi Riyaz,
    your report ZRZ_ORDER_IDOC creates an IDOC with status error 26:
    ‘The segment ZRZSEG2 does not occur at the current level of the basic type ZRZORDER (extension ).’
    … due to lack of hierarchy awareness in form arrange_data_records

    Hi Riyaz,

    Fantastic information & well structured. Thank you!
    I’m new to supporting EDI/IDOC’s & your articles have been useful.
    I’m concentrating mainly on intercompany processing, with the generation of the FI AP entry off the back of an intercompany invoice.
    The business has added new conditions for recharging.
    New condition type posting to a GL that is COPA relevant.
    Basic type INVOIC01
    Postings are successful for both FI & COPA & no errors occur. However, the COPA doc. is lacking many of the characteristic values, e.g., customer, material etc. There is only profit center & company code.
    I think this is due to the fact it is an FI entry.
    I have a feeling the IDOC will need a new segment for the COPA related data?
    Would appreciate your thoughts

    Thanks in advance

    Chandra

        Function module MASTER_IDOC_DISTRIBUTE is generally used to create IDocs. However, when you already have data within your system, you need not create any IDocs. You can directly update the database tables using appropriate function modules locally. Alternatively use the RSEINB00 program.

    Hi Riyaz,

    Can you help me on following.

    I am working on DEBMAS05 Idoc.

    Sender system sending DEBMAS05 Idoc which is an Idoc Extension with two Z segment.

    Now here is my problem.

    In Receving system if i am extending the DEBMAS05 its asking for Access key.Which i don’t want. Is any other alternative of doing this?

    I have two below option but not much clear about it.

    1. If i copy the DEBMAS05 to ZDEBMAS05 and then do idoc extension.In this case do i need to also make ZDEBMAS.

    or i can using DEBMAS as Message type for ZDEBMAS05?

    2. I found one function-exit ‘EXIT_SAPLVV02_001′ in (user-exit VSV00001) which has description ‘Read and Post Additional Export Customer Master Segments’.

    can i use above function-exit in DEBMAS05 without extending the Idoc for Z fields in reciver side.

    i am just evaluating above option so that i do not use Access Key.If above option is not valid then i may use Access Key,

    Please suggest.

    Regards

    Generally, ALE is meant for communicating with different SAP systems. You at least need to get another client configured to try out an ALE scenario and comprehend the configuration steps fully.

    Look at two systems in a broader sense. Say System A belongs to your organization and System B belongs to a rtade partner organization (say a customer or a supplier). So message that goes out from System A to System B, would be defined in the partner’s profile for System B (which is ofcourse defined in System A). Since the message goes out, define it in Outbound parameters. Similarly, System B receives the message from System A. For System B, System A acts as a partner. So define a partner profile for System A in System B. And since the message is incoming to System B, define it in the Inbound parameters.

    For the second question: Whenever you add an ALE partner, you need to add a logical system. You dont have to do client assignment for the partner system. Client assignment is only for your own system i.e. System A in your case. You already have a client assigned to System A. To receive from System Z, define a partner profile for System Z in System A in the Inbound parameters.

    Hope this answers your query.

    Hi Riyaz

    In another scenario i have to connect System A(100) to another system Z(500).

    Where system Z is sending and system A is Receving.
    Now i have already Logical system defined in System A for Idoc transfer to System B. So in in ALE side for getting connected with System Z do i need to create the Logical system again in system A?

    If yes then how could we assign the same client to two different Logical system
    in client assignment part?

    Thanks for clearing my doubts on Logical system. i am new to ALE config

    I have one more problem on Partner profile

    I have two system System A client (100) and System B clint(200)

    System A is Sender and System B is Reciver. I did following settings in my system as per your last post

    I Defined Logical System in System A(100) as

    LS_A and i assigned the LS_A to client 100
    LS_B (No assignement)

    I Defined Logical System in System B(200) as

    LS_B and i assigned the LS_B to client 100

    LS_A (no assignement)

    Now In system A i genrated the Partner profile ( BD64)

    So Two Partner profile LS_ A and LS_B is get genrated

    Now here is my problem:

    I assigned the Outbound Message Parameters in partner profile LS_B in System A

    And In System B , In which Partner profile i need to assign the Inbound Message Parameters to

    Partner profile LS_A or LS_B?

    Please help.

    Check if there are any locks in source and all target systems via SM12 transaction. Otherwise you can create a new model with a new name. If only two systems are involved, you can even create partner profiles manually on each system.

    Hi Shamim,

    Proxies are used where we do not have appropriate BAPI function modules. Proxies are advantageous over RFCs in many ways. They are flexible and speed up the implementation. Have a look at this link for more info. For proxy based scenarios following links may be useful: ABAP client proxies, ABAP server proxies.

    This document was really helpful in understanding the ALE and Idoc concept.

    However, I’ve a question for you: Our requirement is to move data from ECC to CRM system. We thought of using RFC adapter but due to some concerns, we could not implement and finally we’ve decided to use proxy to integrate ECC and CRM systems. I’ve no idea about Proxy (this is the first i’m going to work on integration part). Can you please tell me what is a proxy and how we can use proxy in integrating these two systems and be successfull in moving data from ECC to CRM system?

    Thanks in advance, Shamim.

    A system always uses the partner profile of the partner it communicates with. So source system refers the target by the target’s partner profile created in source system. Similarly, target system refers the source by the source’s partner profile created in target system.

    In short, partner profile is meant to indentify the system we are communicating with.

  45. Riyaz says:

    Hi Sai,

    Please request your Basis administrator to provide you authorization to access transaction SM59. You need to configure ports so that one system can access the other. Ports are nothing but the configuration settings which define the RFC connection which should be used to connect to the partner system. Outbound means messages being sent out from the source system while inbound refers to the messages coming in or being received in to the target system.

    Hope this helps.
