Most formulas will contain at least one variable (otherwise, the result will be the same for each row in the structure). These variables need to be mapped to a specific value source, such as an issue field, progress, another column, or even another formula.
As you write your formula, Structure attempts to map your variables to well-known fields. If Structure is unable to map a variable, it will be marked with a red warning icon, and you will need to map the variable manually.
To map a variable – or to edit an existing mapping – click the variable's name in the variable list or in the formula and select the appropriate attribute from the drop-down list.
Naming Variables
Structure recognizes most standard and custom fields. The trick is to make sure you're entering their names correctly:
- For one-word names, enter just the field name: summary or priority
- For multiple-word names: remove all non-letters and replace any spaces with underscores: story_points
- Variable names are case insensitive, so story_points and Story_Points will both map to the same field.
For a comprehensive list of recognized variable names, see Standard Variable Reference
Even if Structure successfully maps your variables, it's still a good idea to review them!
