FA Account Generator

[hiszaki]

Dear All
I have a problem in Fixes asset addition. In the asset category I was define asset cost with the account & sub account like the following :- (01-000-0000000-111200-001-00000)

111200 #61664; Main account & 001 #61664; sub account.

But when running the depreciation the account was created for the asset addition is 01-000-0000000-111200-000-00000.
So please can any one help me to change the FA Account Generator to read the sub account from the asset category or there are another way?

Thanks
Hisham
