Budget Book in Fixed Assets in eBS 12.1.3

All - Our clients wants to do budgeting for corporate assets. We already have CORP book defined.

Client requirement is as below.

1. Define assets with a future DPIS (say Jan 2015).

2. Define asset cost and other relevant details.

3. Run what-if analysis on these budgeted assets.

4. Compare actual v/s budgeted costs whenever this asset is added in corp books.

Please advise if BUDGET book can be defined in Assets module for achieving this. Does budget book allow adding a new asset which is not in corp book with a future DPIS ?

Any help / documentation is appreciated.

Thanks,

Vishal.
