We have many plant assets all in one class. Each individual asset in the class has differing useful lives. We want to extend the whole plants life by one year, so if one asset has a useful of 10yrs and 6 mos and the unexpired portions is 1 year we want to extend it to 2 years. I can do a mass change but it will change everything to a constant value and that is not what we want, we want to change based on pushing it out one year.. Does anyone know if there is a user exit out there that could be utilized for this purpose?
