ARTIClE
Logical Database, Call by Function Module
This example demonstrates calling a logical database using the function module LDB_PROCESS .
ABAP_SOURCE_CODE
ABAP_EXEC
ABAP_DESCRIPTION
The program reads data using the logical database F1S . First a program-specific selection screen is defined. The data object
wa_spfli is only required here. Next, suitable variables for the interface are declared.
The internal table callback is filled in such a way that, for the two nodes SPFLI and SFLIGHT , different callback routines in the calling program are called. For the node SPFLI , the corresponding routine for GET and GET LATE is only to be called for GET in the case of SFLIGHT .
The internal table seltab is filled with values from the selection table s_carr of the independent selection screen 1100 for the selections of node SPFLI .
The function module LDB_PROCESS is called with these parameters.
The subroutines callback_spfli and callback_sflight are used as callback routines. Since the interface parameter wa is completely typed, the individual components of the work area can be accessed. In callback_spfli , the events GET and GET LATE are handled differently.
