Background documentationData Archiving for High Data Volumes Locate this document in the navigation structure

 

You can use this archiving concept for scenarios with a high data volume. For these scenarios the archiving of data on time is an essential requirement to avoid a data overflow. This archiving concept uses the following archiving objects:

To ensure data integrity, this archiving concept considers the logical relationship between event handlers and event messages.

You can use one of the following archiving sequences:

  • Archiving Sequence Event Handler and Event Message

    This archiving sequence ensures that the event message data is available for as long as possible depending on how you set up the write and delete program for archiving event messages. For example, this enables you to use the data as selection criteria for searches.

    The event handler and the event message reside in application tables because once an event handler or an event message is archived, you can use only a restricted set of selection criteria.

  • Archiving Sequence Event Message and Event Handler

    This archiving sequence ensures that the database volume is reduced. Since the focus in this archiving sequence is mainly on event handlers, the system archives event messages as soon as possible. Therefore, you can only use the set of selection criteria for the event handler.

If you use this archiving concept, consider the following:

  • The archiving and display of event handler sets is not supported.

  • The display of the document flow in the Web interface is not supported.

  • If you assign an archiving profile to a user profile, you cannot use the Retrieve Event Handler Messages for Higher-Level EH option. For more information, see SAP Note 1350818.

  • If you define archive information structures, you must take certain technical considerations into account. For more information, see SAP Note 1350818.

Prerequisites

  • You have made the archiving settings in Customizing for SAP Event Management under   Archive and Delete SAP Event Management Objects  .

  • To query and display data from the database together with already archived data, you have made the necessary settings in Customizing. For more information, see Customizing for SAP Event Management under   Archive and Delete SAP Event Management Objects   Query and Display Archived Data  .

    You have completed the following activities:

    • You have made the Customizing settings for the archiving objects SAPTRX_EH for the event handler object or SAPTRX_EVM for the event message object in the transaction for maintaining archiving objects (transaction AOBJ).

    • You have created and activated the field catalog and archive information structure for the archiving object using the Archive Retrieval Configurator (transaction SARJ).

    • You have defined the archiving sequence.

      Note Note

      You cannot change the archiving sequence in Customizing once you save.

      End of the note.

    • You have defined an archiving profile and a user profile.

    • You have assigned the archiving profile to the user profile that is linked to the Web interface transaction.

    • You have defined the residence time for the archiving object.
