ALE and the R/3 Procedure Model
The
R/3 Procedure Model provides information application-wide for implementing R/3 software.<0} The model is like a phase model, whereby work steps are assigned to each phase and one or more Customizing work steps are associated with each phase.When implementing ALE functions you should refer to the R/3 Procedure Model to ensure that R/3 is implemented in a well structured way.
If ALE is to be supported in an R/3 System installation, implementation of the R/3 Procedure Model is affected at four points:
If ALE business processes are supported, functions and processes must be defined on a cross-system basis. The message types exchanged between the systems are defined in the distribution model.
When defining organizational units like company codes and plants in the R/3 System, it is important to note that these have to be unique worldwide, across all systems. For example, the plant 0001 can only exist in one R/3 System.
