Adjusting Revenue
Thsi is std functionality with the help of 'Adjusting Revenue Events' in PA - M. The problem though am facing is the adjustment Run does not call the billing extn (in our case -- Cost Accrual). IT looks like calling place for this extn is not considered in ADJ run.
Thus we will not be able to do cost accruals for Adjusting Revenue events. Oracle has ER on this.
