    Enter a name for the expression that you are creating.

  • Formula
    Use to write and edit the formula.

  • Search
    Click to launch the Search dialog box.

  • Function Shortcuts
    Click to add an operator to the formula displayed in the Formula box. The Define Formula dialog box provides you with shortcuts to the most commonly used functions; however, you can select these operators from the Functions tab as well. The following is an explanation of each shortcut.

    + Use to add two values together.

    - Use to subtract one value from another.

    * Use to multiply two text values.

    / Use to divide two values.

    & Use to concatenate two values.

    ) Use to end a calculation.

Right-Click Options

To see these menu options, right-click formulas in the Formula box or in the expanded formula area.

  • Expand
    Click to display the formula and its relationship to the context entity. You need to do this when you want to filter or indicate the aggregation level.

  • Rename
    Click to rename the formula displayed in the Formula dialog box.

  • Aggregate to Here
    Click the field name to change the aggregation level. This option is available only after you expand the formula.

  • No filter applied
    If you double-click a field name displayed in the Formula box, the relationship between the entity on which the formula is defined and the field itself is displayed. You can apply a filter to the expression anywhere along the model path. Click to apply a filter to the expression and then click Create a new filter. The Filter Data dialog box opens.
