External Asset acquisition

Hi,

When I am doing external asset acquisition (TTY = 100) using F-90 then document is posted in all ledgers and I know its not an error. But duplicate document is posted only in the tax ledger - and in the document header one document document is posted using F-90 and in the other document header its showing as ASKBN. But I did not run the T-code ASKBN. With out running the ASKBN document is posted in the tax ledger.

Configuration settings for parallel ledger.

1 - 1 - 0L

15 -3- Ledger group

16-4- Tax ledger

Could you please let me know where the configuration settings am I missing? and also could you please let me know why we are getting duplicate documents?

Thanks,

Chandra.
