Adding GRN No. & Qty in standard Asset register in SAP

Hi Everybody,

I would like to include few additional columns in standard asset register such as GRN No., Qty etc.,

This requirement is mainly for asset classes like Computers, Equipments, Furniture etc., to track the original purchase details at the time of retirement (sale / deletion).

Can anybody please let me know how to add these details in asset register. Can we add it in the standard report S_ALR_87011964 - Asset Balances or should we customise it.

Regards,

Hemanth
