Hi Ludwig,
I just realized, in my earlier post in point 4 where I was showing the voucher for the fixed asset acquisition posting, the current layer is showing a debit to fixed asset of only $90 and not $450. The tax layer is showing a debit of $450 to the fixed asset which is correct.
The surprising thing is that the fixed asset balance for the current layer is correct as $450 even when the voucher is of $90. Posting screenshots again for your reference:
Fixed assets posting voucher: Voucher showing $90.
Fixed asset balance: Fixed asset balance is $450 even when voucher is showing only $90.
Inventory transactions: Only serial number S11 is sold and other serial numbers do not have a sold transaction towards fixed asset FURN_FIX-000018
