Export Data to Database in SAP ABAP

Export to Database in SAP ABAP

Understanding EXPORT TO DATABASE

Exporting to a database in SAP ABAP moves data from an ABAP program's internal memory to a database table. This is crucial for data persistence across different user sessions and system jobs.

Using the INDX Table

The INDX table is central to the EXPORT TO DATABASE command. It ensures that each saved dataset is accessible and protected from being overwritten by using distinct IDs as primary keys.

Selection Screen and Memory Storage

A selection screen with a 'run_type' field captures user input. The value is saved to the database with the statement EXPORT run_type FROM lv_run_type TO DATABASE indx(zw) ID 'RUN_TYPE'. This statement makes 'run_type' available to all sessions.

Triggering Data Export with ALV Grid

An ALV grid with a 'booking' button is displayed to the user. Clicking this button initiates an event that imports 'run_type' with IMPORT run_type TO lv_run_type FROM DATABASE indx(zw) ID 'RUN_TYPE'.

Session-Specific Data Export

To keep data session-specific, use EXPORT run_type FROM lv_run_type TO MEMORY ID or TO MEMORY. This approach restricts data visibility to the current session only.

Implementing EXPORT TO DATABASE in Loops

In scenarios requiring multiple datasets to be exported, the EXPORT TO DATABASE statement can be iterated within a loop. This allows for exporting various internal tables to the INDX table efficiently.

Code Examples

Example for exporting to the database: EXPORT run_type FROM lv_run_type TO DATABASE indx(zw) ID 'RUN_TYPE'.

Example for importing from the database: IMPORT run_type TO lv_run_type FROM DATABASE indx(zw) ID 'RUN_TYPE'.

Example for exporting to memory: EXPORT run_type FROM lv_run_type TO MEMORY ID lv_memory_id.

Example for importing from memory: IMPORT run_type TO lv_run_type FROM MEMORY ID lv_memory_id.

Frequently Asked Questions

What is the purpose of the EXPORT TO DATABASE statement in SAP ABAP?

EXPORT TO DATABASE saves a table to a database using the table's primary keys.

How do you specify the target database table when using EXPORT TO DATABASE?

The ID argument to EXPORT TO DATABASE specifies the database table to put the exported table, and it should be a string with two characters.

What is the syntax to export an internal table to the database?

The syntax uses the INDEX argument, such as EXPORT run_type FROM lv_run_type TO DATABASE indx(zw) ID 'RUN_TYPE'.

Are there any limitations when using EXPORT TO/IMPORT FROM DATABASE in SAP ABAP?

Yes, EXPORT TO/IMPORT FROM DATABASE is slow and requires extra code to clean up the database table after use.

What are some best practices when exporting data to a database in SAP ABAP?

Using EXPORT TO/IMPORT FROM DATABASE is the best practice for exporting and importing to/from memory, although it is not limited to memory.
