Hi!

Logical system is created by SALE

Participating systems in a distributed environment must have a unique id. The name of the logical system is used as the unique id. This LS will be a ‘sender’ in outbound interface and ‘receiver’ in inbound interface. In the SAP

sense of word, a logical system corresponds to a client.

To create a logical system:• Expand the tree ‘Logical System’

• Execute ‘Define Logical System’

• Click on push-button NEW ENTRIES

• Enter the name & description of the logical system and

save.

Next step is to allocate the respective logical systems

to it client. Assignments must be unique (that is, a

client may only be assigned to one logical system). This

can be done through transaction SCC4 or by executing

‘Assign Logical System to Client’.

Through BD64 WE CREATE THE DISTRIBUTION model

The applications communicating with each other in

distributed systems are specified in the distribution

model. The systems involved in the distribution must know

which messages are to be distributed. They must know

where the messages are coming from and where they are

going. This information is specified in the distribution

model. The distribution is based on the distribution

model and is directly controlled by it. For each message

flow you can specify filters to specify which data is

sent to which receivers. Each model view is maintained in

the central system and is distributed to other systems

from here.

The following sections show how to model a message flow

between your two logical systems. We are going to

distribute material master data from one logical system

to another.

Modelling involves maintaining model views of the

distribution model. To create a new distribution model

view:• Logon to the logical system from which you want to send

materials to another system (sending system e.g LOGSYS210)

• Execute transaction BD64.

• Select ‘Create model view’. Enter the name and a

description for it.

• Position the cursor on the model view and select ‘Add

Message Type’.

• A dialog box appears. Enter the logical system name of

the sender e.g LOGSYS210 and the receiver e.g LOGSYS260 and the

message type MATMAS.

• Save the distribution model.

Hi

A logical system (LS) is the representation of an R/3 or

external system for distribution of data to and from the

R/3 system. Every R/3 client used for ALE or EDI has to

have a base logical system associated with the client.

This LS becomes the ‘sender’ for outbound messages, and a

‘receiver’ for inbound messages.
