Hi Chirs,
Do you want to archive only the transitional data? If yes, then you need to look into the customizing options such as:
1. Data archiving under Architecture and Technology
2. Define residence times - under basic settings - Transaction.
Also look into the below link which may be useful.
Archiving of Business Transactions - SAP Library
Data Archiving in SAP CRM - SAP Library
Hope this will address your query.
