EA-FIN zero depreciation

Hello Hi,

i have a question regarding the EA-FIN.

I created an asset with below details

Capitalized date: 01.01.2011

Useful life: 10 years

Acquisition value: 15,000

straight line depn.

And then i created below intervals

From: 01.01.1900 - Scrap value: 3,000

From: 01.06.2011 - Scrap value: 6,000

From: 01.09.2011 - Scrap value: 9,000

Then, in AW01N, i check those planned depn value

1 : 100.00-

2 : 100.00-

3 : 100.00-

4 : 100.00-

5 : 100.00-

6 : 0.00

7 : 0.00

8 : 0.00

9 : 269.00-

10 : 47.00-

11 : 47.00-

12 : 47.00-

My question is, why period 6,7,8 are having zero depreciation? It seems that depn in period 6,7,8 are accumulated in period 9.

Any ideas would be appreciated.

Thanks in advanced.
