Can you tell me how Revaluation on CIP Assets work

Hi

We have never revalued CIP assets in any of our Books and we don't have a SLAM event set up to do this.

Our Service Delivery is wanting a new FA Book and on that book they want to add CIP assets, and revalue them. I will need to set up the accounting event to transfer postings to GL, and also to have the entries appear on the Creating Accounting report.

Can you tell me what the accounting posting are if you revalue a CIP assets, and also when does the CIP revaluation reserve start to amortise seeing that CIP assets do no depreciate
