Logical databases are a means by which ABAP reports read and process data. Every ABAP executable program (report) is linked to a logical database specified in the program attributes.

A logical database has a three-character name (for example KDF) where the last letter denotes the application. If you do not specify a name for the logical database when defining the program attributes, the system uses a standard database which controls the formatting of the selection screen but does not read any data.
