ABAP Addition
What does it do? With this addition, the parameter must be assigned to a node> of the structure of the logical database. If a node has type T >, the addition TABLE> can be used instead of NODE>. For a description of the node types, see the statement NODES>>. When the selection screen> of an executable program> that is linked with the logical database is created, input fields are created only for those parameters for which an interface work area> for the assigned node>, or a node below it in the hierarchy, is declared using NODES> or TABLES >> in the executable program. When using the function module LDB_PROCESS>, the assigned node node> must be requested so that the parameter appears on the selection screen.
