Use this field to enter the calculation details (for calculation examples, see Oracle Fusion Middleware User's Guide for Oracle Business Intelligence Discoverer Plus).

To create a calculation, you one or more of the following methods:

  • Type the formula directly into the Calculation field.

    Note: If you type an expression in the Calculation field, you must prefix the expression with an equals sign (=). For example, '=Sales SUM-Costs SUM'.

  • Paste items and functions from the Show field on the left into the calculation.

  • Click the operator buttons underneath the Calculation field to use them in the calculation.

Operator buttons + - x / % ( )

Use these buttons to add operators to the calculation. Operators are copied into the Calculation field.

Note: When you use arithmetic expressions in a calculation, the multiply and divide operators are executed first, regardless of their position in the calculation. If you have more than one operator of the same precedence, they are evaluated from left to right.

For example, the calculation Price – Discount * Quantity is evaluated as Discount*Quantity subtracted from Price. If you use parentheses around the subtraction expression (Price – Discount), the subtraction is executed before the multiplication.


Use this button to validate and save the calculation, as follows:

  • If the calculation has valid syntax, the calculation is saved and displayed in the Calculations dialog.

  • If the calculation has invalid syntax, an error message is displayed. You must correct any syntax errors before you can save the calculation.
