Archiving (CA-ARC)

Reading data which is no longer needed online from the database, and saving this data in an archive file. Archived data are usually deleted from the system.

The archiving relieves the system. Database tables are emptied so that program run-times are reduced because of the smaller data volume which must be processed, and new data can be entered if required.

The archiving can be performed in online mode in the R/3 system because it is performed in a two-step procedure:

• The data are read in the database and written into an archive file, according to the logical selection criteria.
• The archive file is read, and the data flagged for deletion are deleted from the database.
