SAP BW 7.0 - Archiving Data Guide By DAP
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

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.
