FUNCTION - table_parameters
Other versions: 7.31 | 7.40 | 7.54
Obsolete Syntax
... TABLES p1 {TYPE itab_type} | {STRUCTURE struc} [OPTIONAL]
p2 {TYPE itab_type} |
{STRUCTURE struc} [OPTIONAL] ...
Effect
Defines the table parameters t1 t2 ... in the
function module interface display in the source text of function modules. Table parameters are obsolete CHANGING parameters that are typed as
standard tables with a
header line. If an internal table without a header line or a
table body is passed as
an actual parameter to a formal parameter of this type, an empty local header line is generated in the
function module. If an internal table with a header line is used as an actual parameter, both the table
body and the header line are passed to the function module. Pass by value is not possible in formal parameters defined using TABLES.
For information on the TYPE, STRUCTURE and OPTIONAL, see
Properties of the Interface Parameters. The following special rules apply to table parameters:
-
Only pass by reference is allowed in
TABLESparameters. -
After
TYPE, only one table typeitab_typefrom ABAP Dictionary (including type groups) with the table category standard table with a flat row type can be specified. -
A type with
TYPE REF TOis not permitted. -
In non-Unicode programs,
typings using
STRUCTUREdo not have to match the line length of the actual parameter, but do have to be at least the length of the structure.
When TABLES parameters are accessed that are not bound to any type-compliant actual parameters, a special
exception situation can arise.
Note
Formal parameters defined with TABLES can be replaced by formal parameters
defined with CHANGING. A local work area can be created for the internal
table in the function module by using the addition LIKE LINE OF itab of the DATA statement.
Exception
Provided that basXML is not set as the
RFC log, using TABLES parameters for
remote-enabled function modules for
RFC can be significantly faster than passing by means of the CHANGING parameter.
