Generating a Consumer Proxy 
During proxy generation, a proxy class is generated, and from this the actual proxy objects can be instantiated in programs. In addition, (structured) data types for parameter transmission are generated. This proxy functions as a broker with the server of the required Web service.
Procedure
The Enterprise Services Repository Browser (ES Repository Browser) is located in the ABAP back-end system and provides you with a view of the data in the Enterprise Services Repository. Using the ES Repository Browser, you can create, change, check, activate, and delete proxies for all object types – these are usually service interfaces – that were modeled in the Enterprise Services Repository.
The available functions in the Enterprise Services Repository Browser depend on the object state.

Generating Proxies with Industry-Specific Enhancements
SAP provides services for enhancement packages with global data types. These can be used in multiple applications. A global data type can contain fields that are relevant only for a specific industry solution. SAP assigns an industry classification to such fields.
