Hi,
I'm trying to dispose a fixed asset selling it via free text invoice. The fixed asset has 3 books associated because I'm using derived books. I keep on getting this error:

But the accounts for depreciation are there for that book:


All the accounts are included in an active account structure. There are no financial dimensions involved.
Any ideas of what could be wrong? I'm in a Polish company and the check box to allow the sale of the FA is set to yes.
Many thanks in advance.
