The Attribute Calculations dimension contains five members (Sum, Count, Min, Max, and Avg) that are used to calculate and report attribute data:
Sum—Calculates a sum, or total, of the values for a member with an attribute or combination of attributes.
Count—Calculates the number of members with the specified attribute or combination of attributes, for which a data value exists. Count includes only those members that have data blocks in existence. To calculate a count of all members with certain attributes, regardless of whether they have data values, use the @COUNT function in combination with the @ATTRIBUTE function. See the Oracle Essbase Technical Reference.
Avg—Calculates a mathematical mean, or average, of the nonmissing values for an specified attribute or combination of attributes (Sum divided by Count).
Min—Calculates the minimum data value for a specified attribute or combination of attributes.
Max—Calculates the maximum data value for a specified attribute or combination of attributes.
You can change these default member names, subject to the same naming conventions as standard members. See Changing the Member Names of the Attribute Calculations Dimension.
