SELECTION-SCREEN FIELD SELECTION

Short Reference

Syntax

SELECTION-SCREEN FIELD SELECTION
                 FOR {NODE|TABLE} node [ID id].

Effect

This statement defines a node node in the structure of the logical database for field selection. If a node belongs to type T, you can use the TABLE addition 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, you can use an executable program linked to the logical database in the GET statement to control which fields in the node are to be read by the logical database. If you use the function module LDB_PROCESS, the FIELD_SELECTION parameter must be specified accordingly.

For more information on the ID addition, see ldb_additions.

Note

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.
