SELECTION-SCREEN - ldb_additions
Other versions: 7.31 | 7.40 | 7.54
Obsolete Syntax
... FOR {TABLE|NODE} node [ID id] ...
Extras
1. ... FOR {TABLE|NODE} node
2. ... ID id
Effect
These additions of the statement SELECTION-SCREEN
assign a node of the logical database and/or an ID to selection screen elements of a
logical database.
Addition 1
... FOR {TABLE|NODE} node
Effect
This addition means that all the screen elements created with SELECTION-SCREEN
in the selection include for a logical database must be assigned to a node
in the structure for the logical database. If a node belongs to type T, you can use the TABLE
addition instead of NODE
. For a description of the node types, see the NODES
statement.
When the system generates the standard selection screen for an
executable program that is linked to the logical database, it only displays screen elements for which an
interface work area
is declared with NODES
or TABLES
for the assigned node
or a node below it in the hierarchy. If you use the
function module LDB_PROCESS, the assigned node node
must be requested so that the screen element is created.
The FOR TABLE|NODE
addition must be specified for the variants of the
SELECTION-SCREEN statement with POSITION
,
PUSHBUTTON
,
SKIP
,
TAB
, or ULINE
.
You must either assign a node or specify the FOR FIELD
addition for the variant with COMMENT
.
The FOR TABLE|NODE
addition cannot be used in statements to define blocks
or lines with the additions BEGIN|END
OF LINE, BEGIN|END
OF BLOCK, or BEGIN|END
OF TABBED BLOCK, or when copying elements with an INCLUDE
.
Notes
- If none of the elements in a block or a line are created on the selection screen, the entire block or line is not created.
-
If logical databases are no longer created, you do not need to use the variant of the statement
SELECT-OPTIONS
.
Addition 2
... ID id
Effect
This addition defines an ID id
containing a maximum of three characters for
a screen element defined in the selection include for a logical database with a SELECTION-SCREEN
statement. The ID must be specified directly.
The ID can be used to exclude screen elements from a selection screen version with a SELECTION-SCREEN EXCLUDE
statement.
You can use variants of a SELECTION-SCREEN
statement to combine an ID definition
with COMMENT
,
DYNAMIC SELECTIONS
,
FIELD SELECTION
,
FUNCTION KEY
,
INCLUDE
,
PUSHBUTTON
,
SKIP,
TAB, and ULINE
.
Note
You cannot define an ID for blocks defined with
BEGIN OF BLOCK or BEGIN OF [TABBED] BLOCK
, since these are already identified by the name of the block.
