- 1. Create Users for ALE transfer in both receiving and sending client/systems.
Create
users in both the client/systems giving the same user name and proper
authorizations. We need to use these user ids to logon through the
remote connection and perform the IDOC transfers.
- 2. Creating Logical system and assign the client Create logical systems for both sending and receiving systems in both systems.
o Login to Client 100 (SENDER)
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 Logical Systems with naming convention 'system
name'+'CLNT'+client no . For example for sending system ex: DEVCLNT100
o
Create Logical Systems with naming convention 'system
name'+'CLNT'+client no ex: example for receiving system ex DEVCLNT110
o Save and come back
o Click on Assign client 100 to Logical system DEVCLNT100
o Now, logon to client 800, repeat the same above process to create logical systems DEVCLNT110 and DEVPCLNT100
o Save and come back
o Click on Assign client 110 to Logical system DEVCLNT110
- 3. Creating the RFC
In client 100, Go to T. Code SM59
o Expand R/3 Connections
o
Enter RFC Name as DEVCLNT100 (give this name same as that of logical
name created in step1 so that the ports are automatically created)
o Connection Type as 3
o Language as EN
o
Give the logon details for client 110 (usually, we create a new user
with proper authorizations for this ALE data transfer)
o Click on Remote logon button to test the RFC
o
Now, go to client 110 and repeat the same process to create the RFC
connection to client 100, giving logon credentials to client 100
- 4. Configuring Customer Distribution Model(we
usually create this in the original system(sending system) and then
distribute it to other systems. The actual creation of the model
requests that you mention a technical name for the model (unique
identifier in the systems landscape), a sender system, a receiver system
and message types to exchange between those systems.)
o In Client 105, Go to T. Code BD64
o Click on change and Create model view button
o Enter the short text and Technical name as Zdev1_dev2
o Select the model and click on Add Message Type Button,
o Give the Sender as CEVCLNT100, Receiver as DEVCLNT110,
o Give Message type as required, Ex: 'HRMD_A' for HR
Module.(usually Message types given by SAP are available for a
particular module, see this using tcode WE81, if not create a message
type first)
o Note: If we are
performing this data transfer task for all modules at a Customer site,
then we will need to use the appropriate message type and create a new
Distribution model.
o Select the above model view and click on Environment -> Generate Partner Profiles
o Select Transfer IDOC Immediately and Trigger Immediately radio buttonsF
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.
- 5. Configuring and checking the port In client 100, Go to T. Code WE21
o Expand Transactional RFC
o Find the port from the list which is created using BD64 for DEVCLNT110 (Receiving system) RFC Destination.
- 6. Configuring and checking the partner profile In client 100, Go to T. Code WE20
o Expand Partner Type LS
o Select the Partner profile DEVCLNT110
o Double click on Message Type (For Ex: In HR Module, HRMD_A in Outbound parameters.)
o Check Receiver Port is assigned correctly
o Check the Basic type as your Basic IDOC object.
o In the sending system, select the option to transfer IDOCs immediately.
o By default, in the receiving system IDOCS are bunched together and received.
- 7. Creating the message type Message
type defines the 'meaning' of data. It is just a logical entity that
gets connected to the Idoc type (in tcode we82) or gets connected to the
distribution model (in tcode BD64)
o If necessary create a new message type. In client 105, go to tcode we81.
o Click on change, continue
o Click on New Entries button
o Give message type in customer namespace Z* and description
o Save and back
