Select Data Slice (Partition Wizard)
In this optional step of the wizard, you can specify a subset, or slice, of the data in your cube to use as the partition data. To bypass this step, click Next.
Options
Dimensions
View all the dimensions in the cube in the Name column, and view the member you select for each dimension in the Data slice column. The data slice is defined by all the dimension members you select.
Members
Expand members to reveal other members, and then click the member to define the data slice. To remove a dimension member from the data slice, click the dimension name, and then press DELETE.
