Definition

A large number of objects are created during proxy generation. E.g.:

  • ABAP OO Interfaces (in the case of inbound interfaces)
  • ABAP OO Classes (for outbound interfaces)
  • ABAP OO Exception Classes (for fault messages)
  • Dictionary Data Elements (for scalar data type definitions)
  • Dictionary Structures (for messages and complex data type definitions)
  • Dictionary Table Types (for repeat groups, in other words, maxoccurs > 1).

To avoid naming conflicts with classes and ABAP Dictionary objects that already exist, you can assign a prefix to the objects to be generated. This prefix must not begin with an 'X' and an underscore can only be used after the third character ("ABC_", for example).

You can also assign anABAP namespace as a prefix (/CRM/, for example). In this case, you must ensure that the assigned development class is compatible with this namespace.

For some objects, the prefix is enhanced by a technical part, eg 'CX' for exception classes. Prefixes that start with a /, a Z or an Y are set before the technical prefix, ie /CRM/CX_PROXY_EXCEPTION. Other prefixes are set after, ie CX_MYPREPROXY_EXCEPTION. If you want the prefix to be at the beginning even though it does not start with a /, Z or Y, you can split your prefix with a colon. The part before the colon is put at the beginning, the part after the colon is put after the technical part:

MY:PRE will become MYCX_PRE.
