To avoid duplicating names in an outline, you may need to change the name of the Attribute Calculations dimension or the names of the members of the Attribute Calculations dimension.
Regardless of the name that you use for a member, the function of the member remains the same. For example, the Sum member always calculates a sum, no matter what you name it.
To change the names of the Attribute Calculations dimension and the members of the Attribute Calculations dimension:
Open the outline in edit mode and select the Properties tab.
If you want to change the Attribute Calculations dimension name, under the Calculation dimension names node, click the value next to Dimension name is:. In the resulting text box, enter a new name for the dimension.
If you want to change the name of a specific member, under the Calculation dimension names node, click the value next to the member. In the resulting text box, enter a new name, following the proper naming rules.
Click OK.
