EXPORT - Export data


Variants


1. EXPORT obj1 ... objn TO MEMORY.
2. EXPORT obj1 ... objn TO DATABASE dbtab(ar) ID key.
3. EXPORT obj1 ... objn TO DATASET dsn(ar) ID key.

Variant 1

EXPORT obj1 ... objn TO MEMORY.

Additions

1. ... FROM g (for each field to be exported)
2. ... ID key

Effect

Exports the objects obj1 ... objn (fields, structures or tables) as a data cluster to ABAP/4 memory .
If you call a transaction, report or dialog module (with CALL TRANSACTION , SUBMIT or CALL DIALOG ), the contents of ABAP/4 memory are retained, even across several levels. The called transaction can then retrieve the data from there using IMPORT ... FROM MEMORY . Each new EXPORT ... TO MEMORY statement overwrites any old data, so no data is appended.
If the processing leaves the deepest level of the call chain, the ABAP/4 memory is released.

Note

The header lines of internal tables cannot be exported, because specifying the name of an internal table with a header line always exports the actual table data.

Addition 1

... FROM g (for each object to be exported)

Effect

Exports the contents of the data object g and stores them under the name specified before FROM .

Addition 2

... ID key

Effect

Stores the exported data under the ID key in ABAP/4 memory . You can then use the ID to read it in again (with IMPORT ). The ID can be up to 32 characters long.

Note

If you store data both with and without an ID , the data stored without an ID remains separate and you can re-import it (using IMPORT without ID ).

Note

Runtime errors

Variant 2

EXPORT obj1 ... objn TO DATABASE dbtab(ar) ID key.

Additions




1. ... FROM g (for each field to be exported)
2. ... CLIENT h (after dbtab(ar) )
3. ... USING form

Effect

Exports the objects obj1 ... objn (fields, structures or tables) as a data cluster to the database table dbtab .
The database table dbtab must have a standardized structure .
The database table dbtab is divided into different logically related areas ( ar , 2-character name).
You can export collections of data objects (known as data clusters ) under a freely definable key (field key ) to an area of this database.
IMPORT allows you to import individual data objects from this cluster.

Notes


Example

Export two fields and an internal table to the database table INDX :
TABLES INDX. DATA: INDXKEY LIKE INDX-SRTFD VALUE 'KEYVALUE', F1(4), F2 TYPE P, BEGIN OF ITAB3 OCCURS 2, CONT(4), END OF ITAB3. * Before the export, the data fields in * front of CLUSTR are filled. INDX-AEDAT = SY-DATUM. INDX-USERA = SY-UNAME. * Export der Daten. EXPORT F1 F2 ITAB3 TO DATABASE INDX(ST) ID INDXKEY.

Addition 1

... FROM g (for each object to be exported)

Effect

Exports the contents of the field g and stores them under the specified name in the database.

Addition 2

... CLIENT h (after dbtab(ar) )

Effect

Stores the data objects in the client h (if the import/export database table dbtab is client-specific).

Addition 3

... USING form

Effect

Does not export the data to the database table. Instead, calls the FORM routine form for every record written to the database without this addition. This routine can take the data from the database table work area and therefore has no parameters.

Note

Runtime errors

Errors in the structure of the EXPORT / IMPORT database can cause runtime errors .

Variant 3

EXPORT obj1 ... objn TO DATASET dsn(ar) ID key.

Note

This variant is not to be used at present.

Note

Runtime errors
