Linear Method: wrong calculation of first year

i confirm, when prorata temporis is not thicked then we should consider the 1st of January for the computation

Hello Els Van Vossel,

Thanks for your time, I have tried to reproduce your specified scenario which is as follows :

Gross Value : 30000.00
Time Method : Number of Depreciations
Number of Depreciation : 5
Period Length : 12

 for the obtained results i have attached the screen shots i.e (Depreciation_Lines.png).

And i have also checked your attached results and i found that these results are reproduced when the inputs are :

Gross Value : 30000.00
Time Method : Number of Depreciations
Number of Depreciation : 60
Period Length : 1

Hope this will help, and if any query you can revert back. And as per # 2 by qdp, the functionality of prorata temporis is working as expected.

Thanks & Regards,
Devnani Bharat R.

oops, Els wrongly posted her use case. Here is what you should test:

1) Create an asset with a gross value of 30,000.00, purchase date 17/10/2011
2) Select Time Method Number of depreciations, set 60 as number of depreciations, use period length 1, computation method Linear, leave prorata temporis to False.
3) Go to Depreciation board tab and click Compute
=> it gives you depreciation lines as Els posted on comment #1

The bug is: when you sum all the depreciation lines for year 2011, you should have a total of 6000, but here she only got 1500. That's because openerp consider the purchase_date instead of the 1st of January, althought the prorata temporis is not thicked (that's what i wanted to say in my comment #2)
