An array variable can be a Financial Management, Planning, or Essbase execution variable. Arrays contain a list of values that can be multidimensional.
Typically, arrays are used to store variables as part of a member formula. The size of the array variable is determined by the number of members in the corresponding dimension. For example, if the Scenario dimension has four members, the following command creates an array called Discount with four entries. You can use more than one array at a time.
ARRAY Discount[Scenario];
