ALE-IDOC Scenario using Custom IDOC

By SachinDabhade

Aim: Transfer the data from one system to another using user customized IDOC.

Sender System:

Server: 172.25.8.185

Client: 200

Data from Z table: zsach1

ReceiverSystem:

Server: 172.25.9.198

Client: 800

Data from Z table: zsach1

Data is fetched from Z table on the sender system and inserted it in the Z table of Receiver system using ALE/IDOC.

Settings on the Sender End

Table Creation T – Code SE11. The table contains data that is to be sent to Receiver.

ALE Configuration

T-Code – SALE

Defining Logical System

200 is our sender

800 is our receiver

Assigning Client to Logical System

200 is our sender

800 is our receiver

Defining Target System for RFC Calls (Tcode – SM59)

Click on R/3 Connections and then Create TAB

Step 1

Step 2

Save and test the connection.

Defining Port

The sender system is connected to the receiver system through this Port.

Defining Partner Profiles

The partner for client 200(Sender) is the client 800 (Receiver)

Since this is a sender we have to define only Outbound Parameters in this case.

Here you can see the Message type is Z message type.

2. Maintaining Distribution Model ( TCode BD64 )

Create new Distribution Model

Add Message Type

Now Distribute this Model View

Distribute it from Edit Model View Distribute

Defining the Z Segment type

Tcode – WE31

Defining the Basic Type

T Code WE30

Click on New

This will take you to next screen as follows

Here you have connected the basic type to the segment type.

Enter again and this will take you to screen as follows

This shows the relation between the basic and the segment types.

Next you need to make the entry of the segment in the system table.

Tcode : WE81

Next is the following entry which is required.

Here you are specifying the message type and the basic type and the release version.

This is all about the configuration you need to do on the sender side.

Now on the sender side you also need a program that will fetch the required data, couple it in the IDOC format and post it.

Here is a small piece of code that could be useful.

*&---------------------------------------------------------------------**&Report ZSACH_CUST_IDOC **& **&---------------------------------------------------------------------**& **& **&---------------------------------------------------------------------*report zsach_cust_idoc .parameters :p_logsys like tbdlst-logsys.data :gen_segment like edidd-segnam value 'ZSACH'.data :control_dat like edidc,gen_data like z1hdr .tables :zsach1.data: begin of inttab occurs 0,lname type z1hdr-lname,fname type z1hdr-fname,end of inttab.data :int_edidd like edidd occurs 0 with header line,int_edidc like edidc occurs 0 with header line.select * from zsach1 into corresponding fields of table inttab.ifsy-subrc ne 0.message 'no data' type 'I'.exit.endif.control_dat-mestyp = 'ZSACH'.control_dat-idoctp = 'ZSACH'.control_dat-rcvprt = 'LS'.control_dat-rcvprn = p_logsys.

Settings on the receiver side.

The ALE configuration is same as we did it on the sender side. Please refer to earlier pages.

The receiver specific differences are mentioned below.

T-Code – SALE

200 is our sender

800 is our receiver

Steps

Defining Logical System (Same as sender)

Assigning Client to Logical System (Same as sender)

Defining Target System for RFC Calls (Tcode – SM59) (Same as sender)

Defining Port(Same as sender)

Defining Partner Profiles – Here we are accepting the data from Sender system. Hence we need to configure it as Inbound.

Click on the sign above to go to next screen.

Here the message type is to be created again as it was created on the sender side.

The following steps are repeated, as done on the sender side, on the receiver end

Tcode WE30

Tcode WE31

Tcode WE82

Tcode WE81

Here on the receiver end, we need to specify a process code at the time of defining the partner profile.

Process code is something that has the logic defined about what to be done after receiving the IDOC.

In our case, on receipt of the IDOC, we are updating the Z Table. i.e Inserting the data from the IDOC into the Z Table.

Creating a Process Code

Tcode – WE42

The logic associated is coded in the Function Module which is specified in the Identification Field above.

Also the processing type is selected as Processing by Function Module as above.

The function Module is specified in the following

screen.

To have your function Module in the above drop down list, the entry is to be made using the following transaction

TCode – BD51

Once the entry is done here, the function module appears in the drop down list in the previous stage.

Also it is important to make the following entry

Tcode WE57

Function Module will look something as below:

Tcode: WE02

The IDOC has arrived here

Checking the Data

Double click on the IDOC
