Functionality
You only use this module as an example for the interface and fordesigning search help exits insearch helps.
All the interface parameters defined here are mandatory for a functionmodule you want to use as search help exit, as the caller of the moduledoes not know which parameters are actually used internally.
A search help exit is called during the F4 process flow at multipletimepoints. In theCALLCONTROL-STEP, the respective step of the process flow is supplied.If the module only needs to make a few modifications before the step,CALLCONTROL-STEP should remain unchanged.
However, if the module is to carry out the step completely, the nextstep must be returned in CALLCONTROL-STEP.
See also the detailed documentation about the concept of the searchhelp exist.
The module must respond to all steps it does not know or which it doesnot want to handle with an immediate EXIT.
