How Client Extension works for Oracle Project Cost allocation method

Hi Team,

We are looking for enabling the Project Cost allocation method as Client extension and for that we have performed below changes

1) Asset Cost Allocation Method set as "Client Extension" for the project type.

2) ASSET_ALLOCATION_METHOD from PA_PROJECTS_ALL table for the project set as "CE" (client Extension)

3) Modified package "PA_CLIENT_EXTN_ASSET_ALLOC.ASSET_ALLOC_BASIS" and added logic to pick estimated cost from Project asset .

the above client extension package is returning the estimated_cost but post this update "PA_FAXFACE.update_asset_cost" is taking place which is updating projects_asset_all table using below statement
