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 what applications are to run on what systems and what messages are to be exchanged between the applications.
The most important questions customers should ask themselves when working out a distribution concept are:
You should model the logical system as though only one single R/3 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.
