SAP BI Archiving

Business Scenario

In one BI system, the volume of data increases constantly. Constant changes to business and legal requirements mean that this data must be available for longer. In effect, the cost for process, personnel and technology grow. Since keeping a large volume of data in the system affects performance and increases administration efforts. 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, 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, and

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 Info Structures 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 and where to create ‘logical file’: Step 1: Go to transaction code ‘FILE’ in BI, click on ‘Logical File Path Definition’ and select ‘Archive Global Path’ as shown below:

Step 2: Click on ‘Assignment of Physical Paths to Logical Path‘


SAP BI Archiving

Step 3: Select the ‘WINDOWS NT’ and display. This will show the physical path where archive files store.


SAP BI Archiving

Step 4: To create our own/new Logical File, select ‘Logical File Name Definition, Cross-Client’ and ‘New Entries’

Step 5: Enter the following details as shown below-

Logical File: ZXXXX

Physical File: Parameter_<MONTH>_<DAY>.txt

Data Format: ‘ASC’

Application Area: Select the respective area (like SD, FI, MM, etc.)

Logical Path: Select the existing path ‘ARCHIVE_GLOBAL_PATH’ and the save finally.

How to create data archiving process Step 6: To create Data Archiving Process, go to transaction code ‘RSA1’ in BI system, right click on the DSO/InfoCube, click on ‘Create Data Archiving Process’ –


SAP BI Archiving

Step 7: System will assign the archiving object name for the DSO/InfoCube. In the ‘General Settings’ tab, check the box ‘ADK-Based Archiving’.

Step 8: In the ‘Selection Profile’ tab, select the ‘Characteristic for Time Slices’ as a Time Characteristic and select and move left respective InfoObjects on which we need to archive data based upon selection criteria.


SAP BI Archiving

Step 9: In the ‘Semantic Group’ tab, select and move the InfoObjects fro right to left for which we want to archive the data.

Step 10: In the last tab ‘ADK’, enter the newly created logical file name, maintain the ‘Archiving File Size’, select Delete Job as ‘Not Scheduled’. This will not allow system to delete the data automatically from data target.


SAP BI Archiving

Step 11: After creating and maintaining an Archiving Object for a DSO/InfoCube, next job is to archive the data. Go to transaction code ‘SARA’, give the Archiving Object name, and click on ‘Write’.

Step 12: To create a variant, enter a variant name start with ‘ZXXXX’ and click on ‘Maintain’.


SAP BI Archiving

Step 13: In the pop-up window, select ‘For All Selection Screens’.

Step 14: in the tab ‘Primary Time Restrictions’, maintain the details as below:


SAP BI Archiving

Step 15: In the tab ‘Further Restrictions’, give the details if we want to archive the data on certain selection condition.

Step 16: Click on to go back from transaction, system will pop-up a window, click on ‘Yes’ to save.

Step 17: Enter the variant ‘Meaning’ i.e., text.


SAP BI Archiving

Step 18: Click on ‘Start Date’.

Step 19: Click on ‘Immediate’ and ‘SAVE’.

Step 20: Click on ‘Spool Params’.

Step 21: Enter the ‘Output Device’ and press Enter button.

Step 22: Click on ‘Execute’ .


SAP BI Archiving

Step 23: Press the ‘Job’ button to see the job overview.

Step 24: After archiving the data, we need to delete the data from respective DSO/InfoCube. The delete program first read the data from the archive files and then deletes it from data base. For doing this activity, go to transaction ‘SARA’. Enter the Archiving Object name and click on ‘Delete’.

Step 25: Click on ‘Archive Selection’.


SAP BI Archiving

Step 26: Select the archived file and press Enter.

Process for Reloading the Archived Data in SAP BI System 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 we 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. We also can combine reloaded data with current data via multi providers 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 error in customizing or during document selection. Therefore, data should only be reloaded immediately after the erroneous archiving session. If we reload the data, later we may end up with inconsistencies in the database.


SAP BI Archiving

Method 1: Reload Data into Different Data Target (copy of original data target with same

Structure)

Step 1: Go to transaction ‘RSA1’, right click on the original DSO and click ‘Copy’.


SAP BI Archiving

Step 2: Save the DSO as ‘Local Object’ and Activate it.

Step 3: Create Transformation from the original DSO to the copied DSO.


SAP BI Archiving

Step 4: Activate the transformation.

Step 5: Now create DTP for the copied DSO.


SAP BI Archiving

Step 6: Select the settings as below and click on ‘Filter’ to make the selection for which we want to reload the archived data.

Step 7: Click on ‘Change Selection’ and enter the range of value and then press Enter.


SAP BI Archiving

Step 8: Save and activate the DTP and then click on Execute.

Step 9: See the status in Details tab (Green).

We can check and display the data in the copied DSO.


SAP BI Archiving

Method 2: Reload the data into the same InfoProvider.

Step 1: Go to transaction ‘SARA’ and select/enter the archiving object name as shown below.

Step 2: In the menu, select ‘Go To’ and click ‘Reload’.


SAP BI Archiving

Step 3: Press Enter to continue.

Step 4: Select ‘Archive Selection’ and maintain Variant Attribute.


SAP BI Archiving

Step 5: Check the box and press Enter.


SAP BI Archiving

Step 6: Maintain the ‘Start Date’ and ‘Spool Parameters’.


SAP BI Archiving

Step 7: Click on ‘Execute’ button to start the reload process.

We can check and display the data in the original DSO.
