ABAP SELECTION-SCREEN LDB FIELD Statement syntax, information and example SAP source code

SELECTION-SCREEN FIELD SELECTION

Short Reference

ABAP Syntax(Obsolete) SELECTION-SCREEN FIELD SELECTION
FOR {NODE|TABLE} node [ID id].

What does it do? This variant of statement
SELECTION-SCREEN defines a node in the structure of the logical database for field selection. If a node belongs to type T , the addition TABLE
can be used instead of NODE . The statement cannot be used for type C nodes. For a description of the node types, see the NODES statement.
If a node is defined for field selection, an executable program associated with the logical database in the GET statement to control which fields in the node are read by the logical database. If the function module LDB_PROCESS is used, the FIELD_SELECTION
parameter must be specified accordingly.
For more information on the ID addition, see ldb_additions .

Latest notes: While the database program is running, the names of the fields to be read are available in the internal table SELECT_FIELDS in the structure
RSFS_TAB_FIELDS from type group
RSFS .
See also Field Selections .
If logical databases are no longer created, this variant of the statement SELECT-OPTIONS does not need to be used either.
