Hi All.. This is my first POST here.. I am getting this error while Closing period at validation transaction in progress "not updated vouchers in selected period” . Although we have posted all vouchers remaing for period. My guess is inventory vOucher like MPL could be a reason. We just finished year end. this would be the next very period after year end. If you guys could guide me with screen shots that would be great..please see the attached files.. Thanx in advance for your kind help..
