In Harmoni, you can create new items or customized constructions to suit your analysis and reporting requirements. New variables can be created using items that already exist in the project, constructed items, or with user-entered values.

1. Creating a construction from a construction
You can create a construction from:
- A constructed element.
- A combined net element.
- A constructed measure.
- A constructed weight.
You need to select the position in the project tree and then one of the options under construct in the design menu (i.e., new axis, new measure, new weight).
- First, select the position in the project tree and then click “new axis”.
- You need to name your axis and the first element.
- Define your item using the expression editor.
When defining a construction from a construction keep an eye on any possible circular references.
For example, if you have used the constructed axis A (Lifestage) to define is B (Life Stage Overall Satisfaction), you can't then amend definitions in axis A to reference axis B.
2. Updating constructions
Changes in the original construction item definitions will flow to all other items that refer to the original construction.
3. Deleting a constructed item
There may be occasions where you need to delete a construction from your project. Before deleting a constructed item, Harmoni will let you know if has been used in other constructions.
4. Overwriting/Removing a source
As a project owner when overwriting or removing a data source, Harmoni displays a warning message when existing project items are not present in the new data source before you load your project. Learn more.
The warning message gives you information about items that will be removed from your project as well as any constructions that will become invalid as a result.
