Assuming it was a successful completion of the flight test then you can log it as 'PICUS'. If you were unsuccessful it will have to logged as 'PUT.'
That was the eminently sensible logic used by the UK CAA in LASORS.
I see the OP is in Spain - under the pre-EASA regulations of some other European countries such as France the time would have been logged as PUT. This was possibly the case also in Spain. I don't know whether EASA has standardised this yet. Don't assume that EASA has automatically incorporated UKCAA logic!
