... { DATA BUFFER xstr }
| { INTERNAL TABLE itab }
| { MEMORY ID id }
| { DATABASE dbtab(ar) [TO wa] [CLIENT cl] ID id }

Alternatives:
1. ... DATA BUFFER xstr
2. ... INTERNAL TABLE itab
3. ... MEMORY ID id
4. ... DATABASE dbtab(ar) [TO wa] [CLIENT cl] ID id
5. ... SHARED MEMORY dbtab(ar) [TO wa] [CLIENT cl] ID id
6. ... SHARED BUFFER dbtab(ar) [TO wa] [CLIENT cl] ID id
Effect
The data cluster to be
imported can be taken from an elementary data object xstr, an internal table itab, the
ABAP Memory, a database
table dbtab, or a cross-program memory area (if SHARED MEMORY or BUFFERspecified).
... DATA BUFFER xstr
Effect
If DATA BUFFER is specified, the data cluster is taken from the elementary
data object xstr, which must be of the type xstring.
The data object must contain a data cluster which was created using the DATA BUFFER
addition of the EXPORT statement. Otherwise, a
runtime error occurs. Note that the data object cannot be initial.
... INTERNAL TABLE itab
Effect
If INTERNAL TABLE is specified, the data cluster is taken from the internal
table itab. The first column of itab must have
the data type s
or i and the second
column must have the type x. The only table type allowed for itab are
standard tables without
secondary table keys.
The internal table must contain a data cluster which was generated using the INTERNAL
TABLE addition of the EXPORT statement; otherwise, a
runtime error occurs. Note that the internal table cannot be empty.
... MEMORY ID id
Effect
If MEMORY is specified, the data cluster that was written to the
ABAP Memory under the ID
specified in id by the statement EXPORT is imported. id expects a
flat
character-like data object. This object contains the ID of the data cluster, which is case-sensitive.
Note
Outside of classes, an obsolete short form
exists, in which the addition ID can be omitted. This reads the data cluster
saved by the statement EXPORT without an ID being specified.
... DATABASE dbtab(ar) [TO wa] [CLIENT cl] ID id
Effect
If DATABASE is specified, the data cluster that was written to the database table dbtab in the area ar and under the ID specified in id using the statement EXPORT is imported. The database table dbtab must be set up in the same way as described for the EXPORT statement. id expects a flat, character-like data object that contains the ID of the data cluster, which is case-sensitive. The two-character area ar must be specified directly.
After TO, a work area wa that has the same data type as the database table dbtab can be specified. When imported, the values of the database fields that are between the fields SRTF2 and CLUSTR are assigned to the components of wa with the same name. If the addition TO wa is not specified within classes, then no data transport takes place in these components. If the addition TO wa is not specified outside of classes, but the statement TABLES is used to declare a table work area for the database table dbtab, then the values of these database fields are assigned, when imported, to the components of the table work area dbtab with the same names.
If the database table dbtab is client-specific, then a flat character-like field cl can be specified after the addition CLIENT. This field contains a
client ID. If the addition is not specified, the current client is used.
Notes
Example
The table that is imported into the internal table itab is the table exported under the name tab and the ID "TABLE" into the area "SQ" of the database table DEMO_INDX_TABLE (refer to the additions medium of the statement EXPORT). However, the components (which can be selected as required) are assigned to the structure wa_indx.
TYPES:
BEGIN OF tab,
col1 TYPE i,
col2 TYPE i,
END OF tab.
DATA:
wa_indx TYPE demo_indx_table,
itab TYPE STANDARD TABLE OF tab.
IMPORT tab = itab
FROM DATABASE demo_indx_table(SQ)
TO wa_indx
ID 'TABLE'.
cl_demo_output=>write_data( wa_indx-timestamp ).
cl_demo_output=>write_data( wa_indx-userid ).
cl_demo_output=>display_data( itab ).
... SHARED MEMORY dbtab(ar) [TO wa] [CLIENT cl] ID id
... SHARED BUFFER dbtab(ar) [TO wa] [CLIENT cl] ID id
Effect
If SHARED MEMORY or SHARED BUFFER is specified, the data cluster is imported that was written (by the statement EXPORT) to the relevant application buffer of the shared memory in the area ar and using the ID specified in id. The system accesses a memory table of the application buffer whose row structure is defined by a database table dbtab. The set-up of this table is described in the statement EXPORT. id expects a flat character-like data object that contains the ID of the data cluster. The two-character area ar must be specified directly.
For the optional work area wa and client cl, the same applies as for imports from a database table.
