In this example, the Basic Pay has a component order of 67.1.
The number before the dot, i.e., 67, refers to the category as it was defined on the Category screen by the Compliance department when the tax country was created. Only the Compliance and Support To Business departments have access to the Category screen on Bureau level.
The categories have been ordered to ensure components calculate logically. For example, any In Package components will be allocated to a category that is created before the Basic Pay calculates, since it is required to calculate the Basic Pay.
It is only the number before the dot that is important when you consider referencing a component as a source type. The number after the dot, i.e., 1, refers to the order within the category.
