Hi Krishna,
I am bit lost in your explanation here. If your RA method is based on Planned Revenue and that calculates essentially "accruals" to the actual revenue and that is next updating planned revenue and next time RA is recalculated based on a new revenue plan... That does not look neither logical nor transparent or any GAAP compliant.
It looks like you want to update the planned revenue with actual revenue, but again that makes little sense to me, since you will have that actual revenue anyway.
Maybe I simply do not get your requirement, but seems overcomplicated.
Regards,
Paulo
