We are facing the situation below:
Asset are replaced free of charge one by the vendor due to guarantee. For some of them, the depreciation is already started.
Lets say asset bought in 01/ 2013 and deprecation started at this date.
In 10/2013, the vendor replaced it by a new one.
Could you tell me which is the best practice to manage the old and the new asset please?
I want to know which country you are in and which Accounting Standards you are following as per your country to give you a precise suggestion.
But in general, as long as you are not spending any additional cost on acquiring the new asset and it's type and useful life are not changing, you can maintain the same asset number and values in SAP. You could only change the inventory number if you are maintaining any such, to identify the new inventory number. i.e. update the new inventory number in the old asset.
Hope it clarifies.
