TCode F.05 - How to make valuation twice amonth

Hi Gurus,

I have a question from my users. Do you know a process to make the valuation twice a month via F.05? So, the accountancy department do the closing in two step: 1) fast closing and 2) hard closing. Usually they do F.05 only during the hard (last) closing but now they want to do also during the fast (first) closing.

So how to make valuation twice a month without put a mess in the system?

tx a lot for yur advice
