SELECTION-SCREEN FIELD SELECTION
Other versions: 7.31 | 7.40 | 7.54
Obsolete Syntax
SELECTION-SCREEN FIELD SELECTION
FOR {NODE|TABLE} node [ID id].
Effect
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, 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.
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.
-
If logical databases are no longer created, you do not need to use the variant of the statement
SELECT-OPTIONS.
