Reasons for Archiving  Reasons for Archiving  

 Resolves memory space and performance problems caused by large volumes of transaction data

Ensures that data growth remains moderate so that the database remains manageable in the long term

Ensures that companies can meet the legal requirements for data storage in a cost-efficient manner

Ensures that data can be reused at a later date, for example, in new product development

Data Archiving Requirements..Data Data Archiving Requirements..Data semanticssemantics   Hardware independence

Because the encoding of numerical fields, such as integers,

depends on the hardware being used, archiving must ensure that

information about hardware is appended to the archived data so

that the data can be displayed later with different hardware.

Release dependenceBecause the data structure may depend on the release status of

the mySAP Business Suite solution that you are using, record

structure and field definition information must also be archived.

Data DependenciesMany data objects depend on other data objects. Consequently,

when archiving data, we must check whether, in order to archive a

specific data object, another object must first be archived or

whether other objects are to be archived at the same time.       

Data Archiving Requirements…Data Archiving Requirements… Data Data semantics semantics

Enterprise and business structure

Some data is only of use in conjunction with an enterprise’s

organizational structure, such as how it is divided into

different areas for sales. Archiving must therefore ensure that

this information is also archived.

The above list shows that data archiving requires a detailed

knowledge of data semantics and through its application

integration, SAP Data Archiving has taken this aspect fully into

account in its programs and functions. For this reason, SAP’s

application-integrated archiving is superior to archiving

products that are not integrated into mySAP Business Suite

solutions (database tools).

MonitoringMonitoringMonitoring, we should monitor the behavior

of the database and database tables with respect to data growth.

Tools: Database Monitor DB02 Performance Monitor ST04With the Database Monitor (transaction

DB02), you can check the size of database tables and determine their growth behavior in the past.

We can also use SAPDBA and the Performance Monitor (transaction ST04). These tools provide you with additional indicators that can help us make decisions concerning data archiving.

Analyzing and Analyzing and CategorizingCategorizing In this IT process we examine the fastest-growing tables

and those involved in performance-demanding queries in

depth, and group data according to different requirements.

Analyzing and Categorizing, analyze individual database tables and

examine their contents.

categorize the data to later determine which archiving objects you

require. The analyses provide information about which selection

criteria could have the greatest effect during archiving. In this way,

we can avoid examining archiving objects or organizational units

that contribute little to the data volume.

CustomizingCustomizing

Customizing you make different system settings to

control the archiving process. Customizing push

button from within Archive Administration.  It is

divided into Basis and Cross-Archiving-Object

Customizing, entering of Routing Rules and Conditions

(optional) and Archiving-Object-Specific Customizing.

We should determine which data should be

archived ,the corresponding archiving objects.
