Abstract

The purpose of this paper is to explain detailed technical procedure of ADK archiving, deleting and reloadingarchived data in the infoprovider. For archiving firstly create the logical file ZARCHIVE_TEST and physicalfile FIAP__.txt. Archive the data corresponding to the Fiscal Year/Period 009.2007 in theODS 0FIAP_O03 using archiving object BWOFIA~O03 and archive administration. Delete this data from theODS and again reload it from the archive back to the SAP BW system either in the copy of infoprovider orsame infoprovider. Latter is performed only when wrong data was archived due to errors in customizing orduring document selection. Readers who want to understand stepwise implementation of SAP BI ADK

archiving and reloading of archived data will be benefited from this paper,

Business Scenario

The database in our system stores huge amount of historical data which is hardly required for any purposepresently. But for some reasons we want to keep it as we may need to retrieve this data in future. This leadsto increase in BI database which makes the maintenance and administration efforts grow. In effect, the costfor process, personnel and technology grow. So we can remove this data from our data targets store it intoother data storage and reload to the system whenever required. Thus we can increase memory space andthe retrieval performance of the data at query runtime.

Solution BenefitsThe main advantage of ADK archiving is it is a SAP-standard BW solution which is a comprehensiveprocedure for writing, deleting, and storing BW data. Hence, the consistency of the archived data isguaranteed. It allows the use of a blend of cost-effective data storage media. It is platform independent andhandles structural changes in the definition of BW elements. It has easy-to-use front end. Moreover, it offersreduction in resource consumption. The hardware costs for hard drives on the BI side where the online datawill be stored, is reduced if the archiving solution is in place. Below are BW relevant features of ADK :

Handling structural changes: Since the ADK is storing metadata of the archived data as well as the dataitself, it is capable of retrieving the archived data even after structural changes have been made. Thisdata is not converted to the new structure, but simply displayed in the new structure.

Platform independency: The ADK can handle different code pages (ASCII, EBCDIC, UNICODE) and

number formats.

Data compression: The archived data can be compressed up to 5 times of the original data volume.

Archiving Information System (SAP-AS).The archived data can be displayed with the ArchivingInformation System. In BW, the customer has to define the InfoStructures for the respective archivingobjects, and fill them manually within AS customizing.

Administration via transaction SARA: The scheduling, monitoring and management of the archivingsession can be performed with the standard transaction SARA.

How to reload the archived data?

Once the data has been archived on the application server it is stored externally by basis team on separatemagnetic tapes and other storage devices. Whenever such data is again required for reporting the basisteam can bring it back on application server easily. Once it is on the application server it can be reloadedinto a separate data target which is a copy of the original info-provider.

There are two different methods to reload the archived info provider data- reload data into different datatarget or reload into the same infoprovider. It is recommended that you reload the archived data into the copyof the original infoprovider. It allows the reloaded data to remain physically separate from any existing data.

This allows for easier verification of the reloaded archive data because the data is isolated in its ownInfoProvider. You also can combine reloaded data with current data via MultiProviders for better queryperformance because of the systems parallel query processing functionality.

Data should be reloaded into the same info-provider only in emergency cases, in which wrong data wasarchived due to errors in customizing or during document selection. Therefore, data should only be reloadedimmediately after the erroneous archiving session. If you reload the data later you may end up withinconsistencies in your database.
