Defining a Unit

How to create and edit Units

Unit step of the Variable wizard

If this is your first time defining a Unit, we recommend reading the Introduction to Units first

You will most commonly define Units as part of the Variable wizard. You will only need to define a Unit if your Variable is an Assumptions Variable, or if you select the Specify Unit option for a Calculation Variable.

The Unit step is simply a list of Unit Parts, in a standard List View, in which you can Add, Edit and Duplicate Unit Parts. The resulting Unit is shown as a formula at the top of the step.

Each Unit Part can be edited in a separate wizard, or specific properties can be edited individually by clicking on one of the shortcut buttons displayed.

Shortcut buttons (as per above image)

• Change the base Tag and/or Unit Factor

• Change the Order

• Change the Time Type (Flow, Balance, Flow (Constant), Balance (Constant)

• Change the Time Offset

• Add a Context modifier

• Multiply the Order by -1

• Make a copy of the Unit Part

Functionality of the Unit step depends on the context. You will find additional options if your Variable has Dimensions, or if you are creating a Data Point from scratch.

These differences are covered in the relevant sections of documentation.

Default Unit

You can set a default Unit for new Variables by navigating to Model Settings.
