Applies to: SAP BW NW 7.0. For more information, visit the Business Intelligence homepage.

Summary 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. Since keeping a large volume of data in the system affects performance and increases administration efforts, we recommend BI administrator to apply data archiving task if needed.

This guide gives a step-by-step demo to show how to use data archive process (DAP) feature in BI7.0.Firstly, introduce how to create DAP and how to use it to archive data. Secondly, show how to apply cycled jobs to do automatically. Lastly, show how to enable/disable archived data in query.

Preface Using the data archiving process, you can archive and store transaction data from InfoCubes and DataStore objects. This function is not available for write-optimized DataStore objects. The data archiving process consists of three main steps: ...

1. Creating the archive file/near-line object 2. Storing the archive file in an archiving object (ADK-based) or near-line storage 3. Deleting the archived data from the database

Notes: If you use BW 7.0 system, reloading of data into infoProvider is not required as query can access to the archived data.

Part I – Creating Archiving Process

1.1 Using content menu

Step 1: Enter Data warehousing Workbench

Data warehousing Workbench (RSA1) -> content menu of DSO or InfoCube



Step 2: General Settings tab

Step 3: Selection profile

Select profile for archive, when archive data, system will use these infoObjects to restrict certain data.



Step 4: Semantic group

Select semantic group

Step 5: ADK settings

Choose Archive data path.

Notes: ARCHIVE_DATA_FILE is default path, you can change it to customizing setting use T-CODE: FILE



Step 6: Archiving tab

Save and Activate the DAP. Then you will see the Archiving Tab in InfoProvider management area.

Notes: Archiving process will show different status.

1. Lock Status You can lock the selected data area of the archiving request to prevent any changes. This is necessary before data archiving begins.

2. Copy Status The data to be archived is copied into near-line storage or the archive.

3. Verification Status

In the verification phase, the system checks that the write phase was successful and that the data can be deleted from the InfoProvider.

4. Deletion Status When the archived data is deleted from the InfoProvider, the archiving process is complete.

5. Overall Status When all the steps of the archiving request have been completed, you can no longer change the status of the request.

1.2 Using separate T-code

Step 1 : EDIT Data Archiving Process – RSDAP

Choose Object type and InfoProvider name. Click Edit, If DAP does not exist , system will create a new one automatically.



Step 2 – 6: the same with section 1.1

Part II – DAP Management There are two ways to do archiving administration task.

2.1 Using administration function to archive

Step 1 : Create archiving request

In Primary restriction: Choose archiving data restrict with time characteristic;

In Further restriction: Choose your customizing rule to restrict data.



Step 2 : Execute archiving request

Click execute button with background or dialog mode.

Then check the status of the process.

Notes: In InfoCube Archiving Process, system requires infoCube is compressed. So maybe you will meet the error below. The solution is: go to Collapse tab and execute compression job for it.

Step 3 : Delete archiving data

Double click the request before, and choose delete action to execute. Then confirm the status.



Step 4 : Check archiving data

Archiving before

Archiving After



2.2 Using ADK T-CODE to archive

Step 1 : Enter archive administration - SARA

Step 2 : Writing Archiving files

Choose production mode, and input restriction rules



Step 4 : Enter description and save variants.

Step 5 : Maintain start date and print parameters for archive.



Step 6 : Execute the archive background job and monitor the process

Click Job Overview button

Finished!

Notes: you can check the archive files with T-CODE (AL11)

Step 7 : Delete records with exist archive files

Step 1 : Go to reload screen

Step 2 : Go to reload screen, maintain variant and save it

Step 3 : Maintain start date and print parameters for reload.



Step 4 : Execute the reload background job and monitor the process

Part III – Scheduling DAP

3.1 Using process chain to schedule archiving

Step 1 : Create new process chain in T-CODE (RSPC)



Step 2 : Create archiving process variant

Step 3 : Maintain archiving process variant



Step 4 : Create delete archiving variant

Step 5 : Maintain delete archiving variant



Step 6 : Activate process chain

Step 7 : Execute process chain and monitor the process

3.2 Using ADK variant to schedule archiving

When maintain variant of archiving/delete/reload, you can schedule period jobs.



Part IV – Displaying Stored Data in Queries

4.1 Settings of query access

Use T-CODE -> RSRT (query monitor)

Click the read from archive as well
