category
A category is used to parameterize a parameter (resource, budget, indicator or risk).
A category must be linked to a parameter structure. Structures are in global budgets, while categories are in each project. It is the category that manages the display: the thresholds for displaying parameter alerts in the project.

It's essential to set up the measurement structures and categories beforehand. It's difficult to change everything afterwards. The structure is set, as are the representations, which are consistent with what you want to put in place; you don't change the settings again.
