Need details for the Asset cost allocation methods

Hi,

Please let me know how the Asset cost Allocation methods get the CIP cost. (Navigation: PA costing->Setup->Projects->Project type)

Below is my understanding.

1. None --> This comes from the Task to which the asset is assigned

2. Actual Units --> This is given during the asset definition in the capital project form. But from where/how it determine the CIP????

3. Current Cost -> ????

4. Client Extension --> This is custom business logic.

5. Estimated Cost -> This is given during the asset definition in the capital project form.

6. Standard Cost --> I believe this comes from (PA costing->Setup->Capitalization->Assets->Standard Unit Costs)
