ALE Converters and Subsystems

The ALE concept involves using external converters to connect non-SAP systems to the R/3 System.External converters are generic format conversion programs. The following converter functions arecovered by SAP XA-ALE certification:

  • The transfer of R/3 intermediate document (IDoc) formats straight into their own repository so that these data descriptions can be used as source or target structures when assigning data fields.
  • Adoption and conversion of intermediate documents from R/3 Systems via the ALE interface —a remote function call that can be called up using a normal transaction.
  • Conversion of any data format into intermediate document structures and import into the R/3 System via a remote function call in the ALE interface.

What is Class Builder and its purpose?

The Class Builder allows us to create and maintain global ABAP classes and interfaces. Both of these object types, like global data types, are defined in the ABAP Repository, thus composing a central class library. Together, they form a central class library and are visible throughout the system.
