R12 upgrade - Accounting Definitions to be imported ?

Hi,

     We are in the process of Upgrading from 11i to R12. As SLA comes into picture in R12, we have a question of the existing Accounting Definitions. We could see some of the Defintions in the xla_product_rules_fvl table. Also, it was VALIDATED.

      We were having a doubt if we could miss the Accounting Definitions, so we ran the Import Application Accounting Definitions    program, which imported the same defintions with a new date. But, when we tried to Validate the defintiions using Validate Application Accounting Definitions, the program didn't pull out the latest defintions.

Now, my question is....
