Secondary A/D same with A/D Account?

Hi,

I have some questions about defining SDA AAI:

We need to split every depreciation expense in two different accounts (deductible, non-deductible). For accounting purposes, the accumulated depreciation account must be the same.

So far, to map this scenario I found the following "solution": use accumulated depreciation accounts with the same subsidiary like "00" and different object accounts, and define SDA like

12.500

SDA

Secondary

Accumulated Depreciation

00000

N

N

00

O

12

I don't find it very helpful, but is something to start with.

When I generated the monthly depreciation, in F1202, I only got four lines with CHCD (account type) 1, 2, 4 and 5 ( without 3 = Secondary A/D
