PRC: Tieback Asset Lines from Oracle Assets. if asset is split or merged in FA, the asset is not t

We are using Oracle R12.2.4. Fixed Assets was live before Oracle Project Costing.

User trying to add the Project Costing transactions to existing Fixed Assets.

Scenario 1 : The asset X is created in oracle Projects, the generated asset lines and interfaced to Fixed Assets. before post mass additions the asset lines were added to existing Asset Y, then after post mass additions and tieback process in Project Costing the asset X in Project Costing overwritten with Asset Y.

Scenario 2: The asset A is created in oracle Projects, generated asset lines and interfaced to Fixed Assets.

In Fixed Assets before post mass additions the asset lines are added to an existing asset B  of Fixed Assets. Post Mass additions completed and then the asset lines were transferred to another existing asset C. then these asset lines were reassigned back to asset B. user intends oracle to overwrite the asset number A in Project costing for these asset lines as B, which does not happen after running the tieback process.
