Fixed assets: How to reverse Pre-acquisition posted through vendor invoice

In AX 2012 R2 there is a functionality of pre-acquisition, developed for EEUR.

More info:

Pre-acquistion can be posted through pending vendor invoices. If I post the pre-acqusition this way, I have difficulties at reversing it. Of course I can not use the Reversal button. I can post the reversal with vendor credit note, but before that I have to select “Allow negative net book value” in the fixed asset’s value model (it looks like a bug). After I post this, the status of fixed asset is still “Acquired” (it also looks like a bug). I would expect that it would change to “Open”, so that I can change the status to “Suspended”.

Does someone have some better way of posting the reversal?
