Using a level to loop over app data

You can loop and repeat the creation of report elements using data from the Qlik Sense app.

For an overview of levels, see Working with levels.

High-level workflow

This is the recommended workflow for using levels in your PixelPerfect report. It covers some of the most common and simple ways to work with levels in the designer.

Part 1: Add data bindings

First, you need to add the data binding that will be used to cycle the generation of unique report elements. For example, if you want a separate section in the report for each region, you need to add a Region field as a data binding. Data bindings are added in the Field List menu.

This workflow assumes you already have content, in the applicable areas in the template, for which you want to create a level.

次の手順を実行します。

1. Open the Field List menu available from the right-side panel in the designer.

2. Click the plus icon next to Levels.

3. Expand the sections to find the item you want to use. You can select a field from Fields, or an entire chart from any of the sheet sections.

4. Click the icon next to an item to add it as a data binding.

Part 2: Connect the data binding to the band

Next, you need to connect the level data binding to a band.

You cannot bind a level to the default Detail1 band, so you will need to create a new DetailReport band for content where you plan on using a level.

次の手順を実行します。

1. Create a new DetailReport band. See Creating a new band.

2. Select the new band, if not already selected.

3. Open the Properties menu from the right side of the designer.

4. Under Detail Report Tasks > Data Member, select the item to use as the level.
