Contracts are attached to one operating level, organized as follows:
Group: this level enables to gather entities/BU (for example for CPA, Chartered Professional Accountant, who manage data for several clients). This level can be chosen to calculate accounting closures or analysis for all attached items (entities and BU). No contract can be attached to a group.
Entity: usually corresponds to the company (entity is a generic term used by IFRS). Entity should be defined with a currency (operating currency) and an annual closing date
