Hi Devesh
Clear the psa tables because its the only issue
you can find like this db02 and table space overview
and if you want to know which table is occupying more spcace like this go to additional functions bw analysis and you can find psa double click on it so that it will give psa tables and sort in descending order so that you can know which psa is more occupying space and copy that table name and goto se11 or se 16 give table name rstsods and after that you can know which datasource and give a search of that data source and go to manage tab and delete all psa this is the procedure to delete psa manually or else you can do by process chain
first goto table se16 or se11 and give rsds and after that select objvers active so that you can find all datasources which are active in your system and copy all those and goto process chain and create a chain for deletion of psa and add all datasources over there and select more than 10 days or any thing as per your requirement and activate and if you want weekly to run this chain you save it for weekly in start variant so that your chain runs weekly .
I think you got doubt clearly understand please let me know any problem if you faces
