When Fabien? This issue has at least 1.5 Years reported, it is a really needs to have serious accounting implementations running, I think if Trunk already is exploting for new features that just show "new toys", this is one of the features that needs to be in every software of global class as openERP is becoming. Please go up with this wish list as is, and prepare a verification sprint to solve all broken parts on addons related to this. IMHO, If we do this (we already did in our implementations in V5) the work is not so big. Regards. 2011/9/27 Fabien (Open ERP)
