Internal Tables - comp1 comp2 ...
Individual components of internal table rows are addressed in a range of
statements for editing internal tables and in table expressions. If not
stated otherwise, the following syntax applies to the labels
comp1
comp2... :
Syntax
... { comp_name[-sub_comp][{+off(len)}|{->attr}] } | { (name) } ...
Effect
The following alternatives are available for specifying components:
Directly specifying the name comp_name of a component.
If the data type of the components is character-like and
flat , an offset/length +off(len) can be
appended to the name of the component (as in
subfield access ) to access subareas of the component. Only directly
specified numbers or constants can be specified for off and
len .
If the component is structured, the structure component selector -
can be used to access the sub_comp components of the
substructure.
If the component has a reference type, the object component selector
- can be used to access all visible attributes attr of
the referenced object. In this case, a table component can be listed
more than once.
Specifying a parenthesized
character-like data object name , which contains the name of
the component (uppercase) when the statement is executed.
The name of the component in name can contain an offset/length.
The object component selector - can be specified in name
to read attributes, but only those attributes can be addressed that can
be identified statically.
name is not case-sensitive. If name only contains blanks,
this specified component is ignored when the statement is executed. If
name contains a non-existent component, a non-handleable
exception is raised.
Specifying the pseudo component
table_line to address the whole table row as a component.
Notes
A component can only be specified more than once if it has a reference
type. Further components, however, can be specified alongside
table_line . This is necessary, for example, if the row type of the
internal table is an object reference and the value of the reference and
the value of an attribute of the object are to be specified at the same
time.
If the table has a non-structured row type, the pseudo comment
table_line can be addressed as the only component.
The components specified must not be elementary.
If the data type allows it (character-like and flat), an offset/length
can also include adjacent components
A Customizing include must
not be specified as a component if it is empty.
