Crystal Reports for Rational Application Developer Designer Guide

Creating a formula

You can create several formulas at one time to handle different criteria, and then insert them in the report.

To create a formula

  1. In the "Field Explorer" view, right-click Formulas and then click New.
  2. Type the name you want to use to identify the formula.

    Tip: You can also change the name in the "Properties" view. Select the value for the Name property and type the name you want to use to identify the formula.
  3. Double-click your new formula.
    The formula template is displayed on the Formulas page.
  4. Create the formula by typing in the components.
    Tip:
    • Ctrl+Space will bring up a list of the available functions. (For some locales, you need to use a different shortcut to allow Content Assist to display the available functions, such as Alt+/. Check your Eclipse preferences to verify or set the Content Assist shortcut.) If you've started typing, Content Assist will bring up a list of keywords that are possible matches for what you've already typed.
    • Use the Problems view to identify syntax errors in your formula. To display the Problems view, from the Window menu, select Show View and click Problems.

To insert a formula into a report

  1. In the "Field Explorer" view, select a formula and drag it to where you want it to appear on your report.

    Note: A formula that is placed on a report is indicated by @ (for example, @ProcessTime).
  2. From the File menu, click Save to save the changes to the report.
