You can delete archiving requests from the near-line storage, in order to reduce the amount of data in your near-line storage.
Deleting a near-line request involves two steps:
First the near-line request is flagged for deletion.
Next the near-line request is physically deleted.
You can manually flag archiving requests. The system also automatically flags requests in the following cases:
when archiving requests have been reloaded into the InfoProvider
when archiving requests have been set to invalid
In the case of an archiving request without an assigned ADK archiving run (in other words, archiving is exclusively performed using near-line storage), deletion cannot be undone for this request. The archiving request and the near-line request are assigned the final target status near-line request deleted . The time slice of the archiving request remains locked and cannot be revoked. In the case of archiving requests with an assigned ADK archiving run (ADK-based archiving with near-line storage), the deleted data of the near-line request can be reloaded into near-line storage from the ADK later on. This is done using a new near-line request.
Flagging an Archiving Request for Deletion
You are in the Modeling area of the Data Warehousing Workbench. Choose Manage from the InfoProvider context menu in the InfoProvider tree.
Choose the Archiving tab page.
Choose the pushbutton in the Overall Status column for the request you want to delete.
Choose Delete Near-Line Request and then Execute . The near-line request is now flagged for deletion. This is shown by the entry in the Near-Line Request Status column. A near-line request flagged for deletion is no longer visible in the query.
Deleting an Archiving Request
You are in the Process Chains area of the Data Warehousing Workbench. Create a new process chain. More information: Creating Process Chains
Choose ABAP Program as the process type.
Enter the program: RSDA_NEARLINE_REQUEST_DELETE an.
You can schedule deletion for each data archiving process. Alternatively, you can delete all the requests flagged for deletion at the same time.
Reloading a Near-Line Request from the ADK
If an archiving request has been deleted from the near-line storage and an ADK archive also exists for this archiving request, you can reload this request from the ADK into the near-line storage.
You are on the Archiving tab in the InfoProvider administration screen. Press the pushbutton in the Overall Status column for the request that you want to delete from the ADK.
Choose Copy Request from ADK to NLS .
Choose Execute . A new near-line request is created.
The physically deleted request remains visible in the InfoProvider administration screen. This request contains the entry in the Near-Line Request Status column.
