Tips for Generating ABAP Proxies 

Translation and Package Assignment

When proxy objects are generated, the number of ABAP Dictionary objects, classes, and interfaces created can lead to a considerable volume of translation. This translation is pointless, however, since these proxy objects do not appear in user interfaces. You should therefore ensure that proxy objects are separated at package level. Create a separate package for the proxy objects and flag it as Not relevant for translation.

Use Declaration

The packages that contain or use proxy objects must have a use declaration for the package interface SAI_TOOLS. In addition, the corresponding structure package must contain a use declaration for the package interface SAPPINT.

For the proxy runtime, a use declaration must be available for the package interface SAI_SXMS.

Programming (Asynchronous Communication)

If the application data is updated in an appropriate task, make sure that an asynchronous server proxy is also called during this update.  If it is not, the XI outbound processing can be affected by a block in the bg/qRFC queue.
