In the Details tab:
- In Effective, select Yes or No. Setting this field to Yes, tells the calculation engine to consider the resource in calculations (i.e. for this period, the calculation engine takes the resource into account when performing calculation). For example, the figure below indicates a resource that has dates with certain statuses. The Orange range is calculated by the calculation engine and the Yellow range is not.

Note: Since every change in a resource date exists for all the resource dates to follow, if a specific date is changed to be effective or not effective, all the resource dates to follow are updated accordingly. In the above example, if the 30/09 is updated to be effective, the resource is always effective.
- In Resource Types, select the resource type(s) of the resource from the Available list and click
to add them to the Selected list. This field can be different between different dates. Assigning a resource type is useful when you need to create a custom attribute that is specific to this resource and no other ones.
If the resource type does not appear in the Available list, click Add Resource Type. The Resource Type Details page is displayed. Edit the fields and parameters as necessary. For more information, see Adding a Resource Type.
- In Resource Groups, assign the resource to a resource group or groups. This updates the relevant group as well.
- In Services, assign the resource date to a service or services.
- In Contract Parties, assign the resource date to a contract party.
- Fill in the custom attribute fields, if exist, as required. These attributes are displayed if they were created in the Catalog tab.
