Use the Select Members dialog box to select the special members Prompt, Same As, Current Point of View, and User Point of View.
Prompt — Acts like a variable that asks the user to select members. Prompts enable the report writer to filter the dimension members from which the user can select when running the report.
Same As — Creates a column or row member selection with the same member selection setting as another column or row.
Current Point of View — Acts as a variable that employs the POV to specify the member of a particular dimension when the report is run.
User Point of View — Can be selected as a member on the book POV. The parameters can be modified by the end user.
