Data Type Yes/No (Yes/No field: A type of field with content set to either Yes or No; also known as a Boolean field or a True/False field. For example, the Recurring field indicates whether the task is a recurring task.)
Entry Type Calculated (calculated field: A field in which the value is determined by Project based on information in other fields. Project may recalculate the value automatically or when you specify, depending on your choice of calculation settings.)
Description For enterprise resources, a base calendar is selected from those available in the enterprise global template. However, if non-enterprise base calendars are allowed for the projects in Microsoft Office Project Server, the project manager can create a non-enterprise base calendar to use for special situations as needed. The Enterprise Base Calendar field indicates whether the resource is assigned to a base calendar from the enterprise global template.
How Calculated If a resource is assigned to a base calendar that exists in the enterprise global template, this field contains Yes. If a resource is assigned to a base calendar that was created in the project, the Enterprise Base Calendar field contains No.
Best Uses Add the Enterprise Base Calendar field to a resource view if you're using a mix of enterprise base calendars and non-enterprise base calendars, and you need to see which resources are assigned to which calendar types. You can also use this field with Visual Basic for Applications to validate resources as they're brought into the enterprise.
Example In the Resource Sheet, you want to see only those resources that are using a base calendar that exists in the enterprise global template. In the Filter Definition dialog box, you filter for all resources whose Enterprise Base Calendar field is equal to Yes.
Remarks It's recommended that organizations use a naming convention for enterprise base calendars so that they can be easily distinguished from non-enterprise base calendars.
