This is a critical step for the correct functioning of some imports within the Integration menu. To set mapping options for Actuals, Forecasts, Dates and Percent Complete, go to the System Admin, Application Settings menu. Use the External Data tab to set the P6 data source, default options, and settings for the different types of data to be imported. When you initiate imports from the Integration menus described in the subsequent sections of this document, EcoSys uses the options that you have defined on the External Data tab.
