Creating Multi-Column Data Regions

In this article, we will learn how to create multi-column regions in a report model so that you can read data from multiple columns.

1. To create multi-column data regions in your Report Model, go to Files > New > Report Model.

1. Now, specify the File Path of your report for which you want to build the report model. Download the sample PDF file from here.

1. Your report will be opened in the designer window where you can start building its model layout.

1. Right-click on the Record node present in model layout window on the left side of your designer screen and click on Add Data Region.

1. When you click on Add Data Region, you will see a subnode added to Record node in the model layout and Region Properties and Pattern Properties boxes will appear.

1. In the Region Properties section, you will see a check box for Multi-Column region. Check that option.

1. You will see another bar appear just below the pattern-matching bar for setting column boundaries. Click on the second bar above your report where your first column starts. This will create a black dotted line adjacent to your text on the left side. Repeat this for each column. If alignment of your dotted line is wrong, click on it to delete it.

The arrows show the start point for each column.

Multi-Column Region Properties

You can also adjust the Number of Columns and Column Margin by clicking on the “..." option next to the Multi-Column option.

Starting Points box will show the points from where each column is starting. For instance, in this case, Column 1 is starting from “Point 0”, Column 2 from “Point 26” and Column 3 from “Point 52”.

The number of columns correspond to the number of starting points that you will see on this screen. If there are 4 columns, you will see 4 starting points.

There is an option for automatically calculating columns – Automatically Calculate Columns. Here, you can specify:

• Page Margin – where the text is starting from

• Number of Columns – number of columns you want to have in your layout

Astera will automatically calculate and place the margins on your layout.

For instance, there are 3 columns in this report and the page margin is 0.

After specifying the Page Margin and Number of Columns, click on Calculate. Your starting points will be automatically calculated.

Capturing Data from Multiple Columns

After creating multi-column data regions, give a suitable pattern in the pattern-matching bar to select your data region.

For this model shown in the screenshot below, write “Name:” in the pattern-matching bar. You can see that it has selected data regions where the pattern matches.

Increase the Line Count to 7 to capture all data fields.

Highlight the data you want to capture in a field, right click on it and select Add Data Field. You will see that the data in the highlighted data region has been selected and a new field is added to your model. Rename your field using the Field Name box in the Region Properties section.

Repeat the steps for all the fields to build your model layout.

To preview your report model, click on Preview Data option.

Your final output will look like this:
