Access to Archived Data

Use

Data that has been archived using SAP Data Archiving has been removed from the database, but not from the application component. The data is still available for read access and analysis. In some cases, archived data can even be reloaded into the database.

Prerequisites

A prerequisite of read access and reload access, is that the file can be found in the file system. You can check this in Archive Administration.

Features

They following types of access are possible:

• (Read) access to a single data object, such as an accounting document

  Direct access or single document access requires an index that can be filled either during archiving or at a later point. A complex search of the documents stored in the archive files, in which all orders of an article in a particular batch are required for a product recall action, is not possible.

  The Archive Information System (AS) supports direct access using archive information structures, which are a type of index that can be generated automatically either whilst the archive files are being written, or at a later point.

• Analysis of an archive file (Sequential Read)

  It is possible to run an analysis for one or several archiving sessions. The results of the analyzed data objects are displayed in a list. Furthermore, some archiving objects offer the option of a combined analysis. With this option, you can link current data and archived data in the database.

• Reloading to the Database

  Archived data does not usually need to be reloaded because it remains accessible to the applications. There is also a large amount of data that cannot be reloaded or for which reloading is problematic. For this reason, reload programs do not exist for all archiving objects.
