Example 4. This search help depends on FAB class ZCL_IQX_SH_DATA and method GET_GENSEARCHHELP.
Within this method the system makes use of the standard SAP function module BAPI_HELPVALUES_GET.
FAB sends a string delimited by a colon (:) on the field required in the search.
Refer to FAB demo SEARCH_HELP_DEMO where the service is defined.
Also make use of the Data Provider Class provided with FAB that uses
Class ZCL_IQX_SH_DATA and Method GET_GENSEARCHHELP to achieve the
required outcome.
The Standard SAP function module in use within the GET_GENSEARCHHELP method
is BAPI_HELPVALUES_GET.
call function 'BAPI_HELPVALUES_GET'
exporting
objtype = lv_objtype
field = lv_field
method = lv_method
parameter = lv_parameter
explicit_shlp = lv_sh
tables
selection_for_helpvalues = i_sel
helpvalues = i_helpvalues
values_for_field = i_values_for_field
