Cannot retrieve Analytic distribution in Expense, cash regsiter and purchase module

I have installed the module account_analytic_default, account_analytic_plans; but when we encode an expense in HR module and input an distribution analytic account in the expense line, and validate the expense; the invoice appear in accounting module in draaft state but without the analytic distribution. We are obliged to fill again the analytic distribution
The same case appear in cash register module (after closing the cash register) and purchase order (after purchase validation)
I use Open ERP 6.0.4 (latest) for windows
Thanks
