Modeling Distribution


To implement the distribution of business application processes and functions using ALE you need to construct a logical Distribution Model of the whole system. Within the framework of this configuration, customers can specify which applications are to run on which systems and which messages are to be exchanged between the applications.


You should consider the following important questions when formulating a distribution concept:

·        Where are the distributed SAP systems to be installed?

·        What applications are to run on what systems?

·        What master data and transaction data are to be exchanged between the applications?

·        What Customizing data must be known to the distributed systems?

Process Flow

You should model the logical system as though only one single instance is involved. Applications are then distributed across several physical systems in accordance with this model. Most of the organizational units, such as PLANT or SALES ORGANIZATION must be given unique names. Company codes and business areas are the only exceptions to this.
