Data Clusters

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

  • The data objects are written to the storage medium by the statement EXPORT.
  • The data objects are extracted again by the statement IMPORT.
  • The statement DELETE can be used to delete any storage medium.
  • The statement FREE can be used to delete the ABAP Memory.
  • The statement IMPORT DIRECTORY generates 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.

Other versions: 7.31 | 7.40 | 7.54


Note

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