Hi Ferdinand and Amit: There are different methods of depreciation that are relevant to different scenarios. Let me highlight two scenarios here ...and I hope they apply to your respective countries as they do in the United States:
Tax Purposes: Depreciation starts when the asset is put into service, not when purchased. Some companies purchase and put those assets into service right away and therefore depreciation starts right away. The depreciation method for tax (the most common in the US) is MACRS - Double Declining Depreciation Method. Internal (Also referred to as Books): For this purpose, depreciation starts from the purchase date. Depreciation method used is straight line method. I hope this helps.

For business purposes, however, depreciation starts when an item is placed into service. In order to claim a tax deduction, the item must officially start usage before the end of the tax year. hence we need an optional "start usage date" which is used instead of purchase date if entered. the purchase date must be taken from the invoice - invoice-date (mandatory) it will almost never be 'purchase_date': lambda obj, cr, uid, context: time.strftime('%Y-%m-%d'), this is a source of errors,especially if the invoice arrives in the month after issued from the supplier.
