To store and read data clusters, ABAP offers the following statements:
· EXPORT parameter list TO medium
· IMPORT parameter list FROM medium
The data cluster is defined with help of a parameter list parameter list, (see keyword documentation), and specifies the Storage Medium in medium.
You can write a directory of the data objects of a data cluster to an internal table using the statement IMPORT DIRECTORY.. The data cluster was stored in a database table using EXPORT.
To delete data clusters, you can use the following statements:
· FREE MEMORY deletes all data cluster from the ABAP memory
· DELETE FROM ... ID id deletes a data cluster with the identification id, which was stored in the ABAP memory of a database table, or in an application buffer of an application server.
For further details about these statements and additions, see the keyword documentation.
