Formulas are calculated from DBFields, other formulas, summaries, and parameters. This topic introduces how you can insert formula fields in a report and add conditional formatting to the formula fields.
This topic contains the following sections:
See an example: The SampleComponents catalog, included with Designer, contains reports that have examples of how you could use each component type in a report. For the formula field example, open
You can insert formula fields in the report areas listed in Component Placement.
For a business view-based report
Select the formula from the Dynamic Resources > Formulas node in the Data panel and drag it to the destination.
For a query-based report
You can insert a formula into a query-based report using either of the following two methods:
- By dragging and dropping
In the Data panel, select the formula from the Formulas node , then drag it to the destination. If the predefined formulas are not what you want, select the <New Formula...> item to create one as required.
- Using dialog box
- Position the mouse pointer at the destination where you want to insert the formula.
- Navigate to Insert > Formula or Home > Insert > Formula. Designer displays the Insert Fields dialog box.
- Select the required formula from the Formulas node. You can select multiple formulas to insert them all a time.
- If you select multiple formulas, in the Insert Layout box, specify the layout of the formula fields in the report. By default, Designer arranges them in the default layout. You can arrange the formula fields horizontally or vertically by selecting Horizontal or Vertical, and customize the space between them.
- Select Insert to insert the formula fields into the destination.
- In a query-based report, not all formulas in the catalog are valid in the current context, so under the Formulas node in the Insert Fields dialog box or the Data panel, Designer only lists the valid formulas that are based on DBFields from the current dataset.
- If you insert a formula into the detail panel of a data component, Designer automatically inserts its name as a label into the corresponding header panel; otherwise, Designer places the formula and its name label in the same panel. If you do not want Designer to insert the name label automatically, clear "Insert field name label with field" in the Component category of the Options dialog box.
You can add conditional formatting to formula fields in a report, so the field values that meet a specified condition can automatically apply the formatting you define for the condition. This is very useful to highlight values that users may need to act on at runtime.
To apply conditional formatting to a formula field, right-click it and select Conditional Formatting from the shortcut menu, then take the same procedure as described in Adding Conditional Formatting to DBFields.
