Functionality
This function module is used only as an example for the interface andthe layout of search help exits insearch helps.
All the interface parameters defined here are required for a functionmodule that is to be used as a search help exit. This is because themodule caller does not know which parameters are used internally.
A search help exit is called up for multipleeventsduring the process flow of the F4. Each flow step is specified inthe CALLCONTROL-STEP. If the function module wants to make only a fewmodifications before the step, the CALLCONTROL-STEP must not be changed.
If, however, the step is completely transferred by the module, thefollowing step must be returned in CALLCONTROL-STEP.
See the comprehensive documentation on the concept of the search helpexit for more information.
The module must respond to all steps that it does not know, or that itdoes not want to process with an immediate EXIT.

Description
Current search help, categorySHLP_DESCR_T.
At timepoint SELONE, the search help assigneddirectly to the field is transferred. This can also involve acollective search help. The corresponding elementary search helps are inSHLP_TAB. At all later timepoints the elementary search help that waseither selected in the dialog or was directly assigned to the fieldfrom the start is transferred.

Description
If the data selection is carried out by the search help exit (stepSELECT), the hit list must be returned in this table in internal displaymode.
If the data display is carried out by the search help exit (step DISP),the hit list is transferred in this table in internal display mode.

Description
This table is of particular relevance to the SELONEevent(selection of an elementary search help with multiple options).
It contains the complete description of an elementary search help ineach line (line category is SHLP_DESCR_T). You can restrict the number of elementary search helps byadapting SHLP_TAB. You can normally retain SELONE as the next step. Theuser is then offered the restricted quantity of elementary search helpsfor selection.
The corresponding collective search help is provided for the SELONEevent in the SHLP parameter.
Only if the SELONE event has more than one entry in SHLP_TAB, and theselection dialog box is not to be displayed, should you change the nextstep to PRESEL1. The search help to be used then needs to be transferredfrom SHLP_TAB to SHLP in advance.
