Introduction

top

In this tutorial, we will walk through setting up a Union sub query. A good way to think about Unions is - use them if you need to combine multiple fields into the one column, either from the same or different views or sources.

In this scenario our main report will have a list of invoicing figures by region, we will then use the Union query to display negative cost figures in the same column, and then add sub totals to see the total income for each region.

 

Master Query

The Master Query is going to include:

  1. Camp Region
  2. Calculated Field: "Invoiced" text label
  3. Sum Invoiced Amount

 

Union Query

The Union Query will include:

  1. Camp Region
  2. Calculated Field: "Cost" text label
  3. Calculated Field: Sum Cost * -1 (to convert the Cost figures to a negative value)

Master Query

4. Drag and drop the Camp Region dimension and Invoiced Amount metric into the Columns list.

 

Label Field

To complete the master query, a label field is required. This will be used to identify the rows from the master query as "Invoiced" rows. There will be a similar calculation in the union query to identify rows as "Cost".

5. Click on the + to create a calculated field, in the bottom of the View Fields List panel.

6. Set the Calculated Field Name to Label
Note: the name for this field can be anything, it will not change the way the union works if it's called something else.

7. Type Invoiced into the text box under the main calculation panel, as shown here, and click + Add to add it to the calculation.

8. Click the Validate button to ensure your calculation is built correctly.

9. Click the Save button to complete your calculation.

10. Drag the Label calculation to between the Camp Region and Sum Invoiced Amount fields in either the Columns list or Table Preview.

Calculations

To complete the union query, two calculations will be required;

  1. Label: this will be used to identify the rows from the union query as "Cost" rows. There will be a similar calculation in the master query to identify rows as "Invoiced".
  2. Cost: this will be used to convert the cost figure to a negative value. This will mean that when a sub total is added to the report, the cost amount will be subtracted from the invoiced amount.
