If multicurrency budgeting and forecasting or project currency is used, sometimes errors occur if the currency code on the activity connected object is not present in the currency rate types used for budgeting and forecasting which is specified in Project Setup Parameters/Currency tab. This is indicated by the error option related to activity connected object which is automatically enabled and a description saved for the error. In this case calculations can not be performed for the currencies Base Currency at B&F Rate and/or Project Currency. By adding the missing currency code to the relevant rate types the errors can be corrected.
