Asset Retirement Obligations & Write-ups in R12

Per FAS 143, client needs ability to account for Asset Retirement Obligations (AROs) and I have yet to see any explanation of how to accomplish this in the FA module. We have explored several options including:

1. Manual GL transaction first : CR ARO Liability (for amount of ARO liability as determined by management), DR Asset Clearing. Then book asset adjustment in Fixed Assets with a comment of "ARO" for the amount of the ARO. This will CR Asset Clearing, DR Asset Cost.
Asset Transaction History Report could be used for reporting on asset transactions, if a lower level of detail is required for reporting, a custom report will have to be developed. A risk with this approach is that if someone mistypes the adjustment description, or forgets to type it at all, the adjustment will still book to the GL but without the description. This risk is mitigated by the fact that a centralized person/group of people would have access to make asset adjustments.
