You edit logical databases using the Logical Database Builder in the ABAP Workbench. To start the Logical Database Builder, use Transaction SE36 or SLDB, or choose Tools ® ABAP Workbench, followed by Development ® Programming environment ® Logical Database Builder. You can also start it by forward navigation from the Repository Browser or other ABAP Workbench tools.
In the Logical database field, you can enter a name of up to 20 characters. The name may also contain a three to ten-character namespace prefix, enclosed in forward slashes.
On the initial screen, you can create, copy, and delete logical databases. However, you can only delete a logical database if it is not linked to an executable program. Even if a logical database is not linked to any executable programs, it can still be used by a program that calls it using the function module LDB_PROCESS. Before deleting one, you should therefore check that it is not still in use. However, the Where-used list function only shows where a logical database is assigned to an executable program.
You can select the individual components of the logical database directly. When you are editing a logical database, two arrow icons appear in the application toolbar that allow you to navigate backwards and forwards between the most important components. You can also use the normal Goto function to navigate between components.
