# Report Builder

The Report Builder is a tool to create your own database reports. Unlike with the Report Wizard, using the Report Builder you can take control to design the report the way you want. The generated report is a Writer document that you can edit, too.

To use the Report Builder, the Java Runtime Environment (JRE) software must be installed, and this software must be selected in LibreOffice.

## To install the JRE software

The Report Builder requires an installed Java Runtime Environment (JRE).

1. Choose LibreOffice - Preferences Tools - Options - LibreOffice - Advanced.

2. Wait up to one minute, while LibreOffice collects information on installed Java software on your system.

   If a recent JRE version is found on your system, you see an entry in the list.

3. Click the option button in front of the entry to enable this JRE version for use in LibreOffice.

4. Ensure that Use a Java runtime environment is enabled.

If no JRE version is found on your system, open your web browser and download the JRE software from http://www.java.com. Install the JRE software. Then restart LibreOffice and open LibreOffice - Preferences Tools - Options - LibreOffice - Advanced again.

## To open the Report Builder

1. Open a Base file or create a new database. The database must contain at least one table with at least one data field and a primary key field.

2. Click the Reports icon in the Base window, then choose Create Report in Design View.

   The Report Builder window opens.

The Report Builder is divided into three parts. On the top you see the menu, with the toolbars below.

On the right you see the Properties window with the property values of the currently selected object.

The left part of the Report Builder window shows the Report Builder view. The Report Builder view is initially divided into three sections, from top to bottom:

1. Page Header - drag control fields with fixed text into the Page Header area

2. Detail - drag and drop database fields into the Detail area

3. Page Footer - drag control fields with fixed text into the Page Footer area

To insert an additional Report Header and Report Footer area choose Edit - Insert Report Header/Footer. These areas contain text that appears at the start and end of the whole report.

Click the "-" icon in front of an area name to collapse that area to one line in the Report Builder view. The "-" icon changes to a "+" icon, and you can click this to expand the area again.

You insert database fields by drag-and-drop into the Detail area. See the section "To insert fields into the report" below.

In addition, you can click the Label Field or Text Box icon in the toolbar, then drag a rectangle in the Page Header or Page Footer area, to define a text that is the same on all pages. You enter the text in the Label box of the corresponding Properties window. You can also add graphics by using the Graphics icon.

## To connect the report to a database table

1. Move the mouse to the Properties view. You see two tab pages General and Data.

2. On the Data tab page, click Content to open the combo box.

3. Select the table for that you want to create the report.

4. After selecting the table, press the Tab key to leave the Content box.
