Archiving of Settlement Documents 
The settlement documents use up additional storage space. Once a posting period in Controlling (CO) and Accounting (FI) has been closed against further posting, the settlement documents can be archived. Be sure to include a safety margin when you specify the residence time in the settlement profile.
In Customizing for Product Cost Controlling, you use the residence time in the settlement profile to determine how long the settlement documents are kept in the SAP system. You can:
Archive the settlement documents directly
Archive the settlement documents when you archive the order
Note
Settlement documents can be removed after the posting period in Controlling and in Financial Accounting is closed for posting. You should, however, allow a safety period before doing this because the settlement documents may still be needed for reversal of settlement and for a repeat of the period-end closing.
The reorganization involves two steps:
The settlement documents are archived.
The data is deleted from the SAP system.
This ensures that data is not deleted from the database until it is actually present in the archive.
Archiving can only be carried out as a background job. You use a variant for the archiving program to determine which data is to be archived and whether the data is to be deleted from the database.
You can select settlement documents for archiving using the following parameters:
Settlement sender
Controlling area
Document number
Object number of the settlement sender
Latest posting date
Generate Archive starts a function that reads the archived data and deletes it from the database if necessary.
