Data Clusters

A data cluster is a group of data objects grouped together for the purpose of storage in a memory medium that can only be edited using ABAP statements.

• The data objects are written to the memory medium by the statement EXPORT.

• The data objects are extracted again by the statement IMPORT.

• The statement DELETE can be used to delete any memory medium.

• The statement FREE can be used to delete the ABAP Memory.

• The statement IMPORT DIRECTORY creates a list of all data objects that have previously been exported to a database table.

The statements for data clusters are complemented by the subclasses of the abstract system class CL_ABAP_EXPIMP_UTILITIES.

Note

As well as the statements described here, some obsolete accesses to data clusters also still exist.

This translation does not reflect the current version of the documentation.
