Abstract

The purpose of this paper is to explain detailed technical procedure of ADK archiving, deleting and reloading archived data in the infoprovider. For archiving firstly create the logical file ZARCHIVE_TEST and physical file FIAP_<MONTH>_<DAY>.txt. Archive the data corresponding to the Fiscal Year/Period 009.2007 in the ODS 0FIAP_O03 using archiving object BWOFIA~O03 and archive administration. Delete this data from the ODS and again reload it from the archive back to the SAP BW system either in the copy of infoprovider or same infoprovider. Latter is performed only when wrong data was archived due to errors in customizing or during 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 purpose presently. But for some reasons we want to keep it as we may need to retrieve this data in future. This leads to increase in BI database which makes the maintenance and administration efforts grow. In effect, the cost for process, personnel and technology grow. So we can remove this data from our data targets store it into other data storage and reload to the system whenever required. Thus we can increase memory space and the retrieval performance of the data at query runtime.

Solution Benefits

The main advantage of ADK archiving is it is a SAP-standard BW solution which is a comprehensive procedure for writing, deleting, and storing BW data. Hence, the consistency of the archived data is guaranteed. It allows the use of a blend of cost-effective data storage media. It is platform independent and handles structural changes in the definition of BW elements. It has easy-to-use front end. Moreover, it offers reduction in resource consumption. The hardware costs for hard drives on the BI side where the online data will 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 data itself, it is capable of retrieving the archived data even after structural changes have been made. This data 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 Archiving Information System. In BW, the customer has to define the InfoStructures for the respective archiving objects, and fill them manually within AS customizing.

Administration via transaction SARA: The scheduling, monitoring and management of the archiving session 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 separate magnetic tapes and other storage devices. Whenever such data is again required for reporting the basis team can bring it back on application server easily. Once it is on the application server it can be reloaded into 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 data target or reload into the same infoprovider. It is recommended that you reload the archived data into the copy of 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 own InfoProvider. You also can combine reloaded data with current data via MultiProviders for better query performance because of the system’s parallel query processing functionality.

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