Transaction CJ88 is indeed responsible for posting assets from the project. It posts with transaction type 331 in the standard system. It is factually correct that depreciation is distributed over the remaining useful life when depreciating with transaction type 331. It appears that your desired settings do not optimally match the standardized execution of SAP. There is no provision for post-capitalization when using CJ88, as the transaction operates on special provisions of Asset Accounting and was created for dealing with fixed assets in a project environment. If you have a firm requirement for post-capitalization, you could instead try to achieve this via transaction ABNAN, which you have already mentioned. Otherwise, you may need to speak with your SAP expert or SAP contact to find a customized solution or adjust business processes accordingly. As always in SAP, remember that potential changes need to be tested carefully to avoid unintended consequences. Please note that this information is based on my current knowledge of SAP and functions or processes may differ depending on the version and individual system configuration.
