Problem: ETL performance with the Earning Transactions

The current structure with earning fact table(cn_f_earning_txns), before loading the new transactions and update the surrogate keys of all the dimensions, it deletes all the transactions which were updated/deleted in the source EBS-OIC instance.

The fragmentation can be eliminated by reorganizing the database objects. But all Customers cannot allocate the time and resource for the re-organization of the fact table cn_f_earning_txns, if it is referencing 24*7.
