Hi praveen,
Greetings!
I am not sure whether you are a BASIS or Functional guy but, if you are BASIS then you can discuss with your functional team on selecting the archiving objects inline with your project. Normally, func consultants will have the knowledge of which archive object will delete entries from which tables... You can also search help.sap.com for identifying the archiving objects.
Once you identified the archiving objects, you need to discuss with your business heads and key users about your archiving plan. This is to fix the data retention period in the production system and to fix the archiving cycle for every year.
Once these been fixed, you can sit along with func guys to create varients for the identified archiving objects. Use SARA and archivie the concerned objects.
Initiating a archiving project is a time consuming task. It is better to start a seperate mini project to kick off the initial archiving plan. You can test the entire archiving phase in QA system by copying the PRD client.
The below summary will give you a idea to start the archiving project,
1. Identify the tables which grow rapidly and its module.
2. Identify the relevent archiving object which will delete the entries in rapidly growing table.
3. Prepare a archive server to store the archived data ( Get 3rd party archiving solution if possible). Remeber, the old data should be reterived from the archive server when ever the business needs it.
4. Finalise the archving cycle inline with your business need.
5.Archvie the objects using SARA.
6.Reorganize the DB after archiving.
Hope this will give some idea on archiving project.
