One of the options when linking to a Primavera P6 schedule is to link directly to a P6 database. To do so you must first configure a P6 database connection in this page. You can create as many profiles as you wish and designate one as the default. See Schedules for information about linking schedules.
PRIMAVERA CHECKBOX
If checked, the "Primavera" option appears in the Application dropdown list in the Link Schedule Dialog. This has no effect on the "Primavera XML" option, which is always available.
