Converting previously capitalized expenditures to R12 Capital Project without allowing them to be ca

We're in the process of converting from a mainframe legacy system to Oracle EBS R12.1.3 and will be using Project Costing (will have Capital projects only) to capture CIP costs and create assets that will interface to FA.

We're using web ADI to upload the previously capitalized expenditures to Oracle, and bringing them in fully costs and GL Accounted.  What we're experiencing is that these lines are flagged as capitalizable and are being brought into the capital project lines during the Generate Asset Lines process, and are available to assign to an asset and interface to FA.  These costs are coming into the same project task as current non-capitalized CIP costs, for budgetary reporting reasons, so the task cannot be marked un-Capitalizable.
