Using Logical Databases Locate the document in its SAP Library structure

There are two ways of using a logical database: Either by linking it with an executable program, or by using the function module LDB_PROCESS in any ABAP program.

This graphic is explained in the accompanying text

When you link a logical database to an executable program, the user can enter values on the selection screen, and the data read by the logical database is passed back to the program using the interface work areas. If you call the logical database using a function module, the selection screen is not displayed. The calling program does not have to provide interface work areas. Instead, it uses special subroutines called callback routines, which are called by the function module and filled with the required data.
