Here are the steps for creating custom idocs.

Creating Custom IDoc type and Message type

All the objects created should be present on both source as well as target system(s).

1. Create segments – Transaction WE31

Create a segment ZRZSEG1

Add all fields of table ZCUSTOMERS to it

Save the segment

Release it using the menu path Edit -> Set Release

Similarly create two more segments given below

Seg. ZRZSEG2 – to hold all fields of table ZSOHEADERS

Seg. ZRZSEG3 – to hold all fields of table ZSOITEMS

2. Create Basic IDoc type – Transaction WE30

Create a Basic type ZRZORDER

Add the created segments in the hierarchy shown

Maintain attributes for each of the segments

Save the object and go back

Release the object using the menu path Edit -> Set Release

3. Create/Assign Message type – Transactions WE81/WE82

Go to WE81

Create a new Message type ZRZSO_MT

Save the object

Go to WE82 and create new entry

Assign the message type ZRZSO_MT to the basic type ZRZORDER

Also specify the Release Version

Save the object

Outbound Settings

Define Logical Systems and Assign Client to Logical System – 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

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

till 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 etails about generated IDoc

dsplay appropriate log

Inbound IDoc Posting Function Module

In the receiving system, create a function module Z_IDOC_INPUT_ZRZSO_MT using SE37. Below, I have described the logic for the same.

Add Include MBDCONWF. This include contains predefined ALE constants.

Loop at EDIDC table

Check if the message type is ZRZORDER. Otherwise raise WRONG_FUNCTION_CALLED exception

Loop at EDIDD table

Append data from the segments to appropriate internal tables

For example: append data from ZRZSEG1 segment to the internal table of type ZCUSTOMERS

Update the DDic tables from internal tables

Depending on the result of the update, fill the IDoc status record (type BDIDOCSTAT) and append it to the corresponding table.

Status 53 => Success

Status 51 => Error

Inbound Settings

Define Logical Systems – Transaction SALE (Please refer to Outbound Settings discussed in previous part)

Assign Client to Logical System – Transaction SALE (Please refer to Outbound Settings discussed in previous part)

Maintain RFC Destinations – Transaction SM59 (Please refer to Outbound Settings discussed in previous part)

Define Ports – Transaction WE21 (Please refer to Outbound Settings discussed in previous part)

Generate/Create Partner Profile – Transactions BD82/WE20 (Please refer to Outbound Settings discussed in previous part)

Assign Function Module to Logical message – Transaction WE57

Create a new entry

Specify name of the Function Module as Z_IDOC_INPUT_ZRZSO_MT

Also, specify Type as F, Basic IDoc type as ZRZORDER, Message type as ZRZSO_MT and Direction as 2 (Inbound)

Save the entry

Define Input method for Inbound Function Module – Transaction BD51

Create a new entry

Provide Function Module name as Z_IDOC_INPUT_ZRZSO_MT

Specify the Input method as 2

Save the entry

Create a Process Code – Transaction WE42

Create a new Process Code ZPCRZ

Select Processing with ALE Service

Choose Processing type as Processing by function module

Save the entry

On the next screen, select your function module from the list

Save the changes

Now you will be taken to the next screen

Double-click on Logical message

In the Assignment to logical message, specify the message type ZRZSO_MT

Save the changes

Send and receive data

On the sender system, execute the IDoc Generation Program. Check the status of IDoc using transaction WE02.

Check the status of the IDoc in the receiver system using transaction WE02. You can also check the contents of DDic tables to make sure that the records have been created in the receiver system.
