All types of service terms are 'life cycle aware'. This means that you can have multiple versions of the same terms, which are valid at different points in time. Fields referring to these terms, for example on Orders, are called 'snapshot reference' fields. They show the terms that actually apply to the selected order. Consequently, these are not necessarily the terms that apply on the reference date. For each type of term, snapshot reference fields exist, referring to the actual terms applied. For more information on the snapshot fields, see Order revenues - fields and Work Orders - Service Provider fields .
