We just upgraded to V13.1 and found a bug on the navigation on Cost Plan details. When you open a CP detail with only one year of budget, you will not get any next periods/previous periods navigation on the timescale of budget per month. Fine because there are none, but if you then navigate to another CP where there are more periods in previous and future years, the navigation buttons are still not there. If I logof/logon and go to the CP with multiple years the the navigtion buttons are there. Does anyone else have this problem too and found a better workaround then logof/logon?
