Contract
A contract is an agreement between two parties to deliver goods or services. Contracts contain:
General agreements that apply to the contract as a whole.
Agreements on the items/services to be delivered such as property, rentable unit, space, asset to which it applies.
Price agreements for each item/service that is delivered. These price agreements vary in time.

A contract is a hierarchical element and can therefore contain subcontracts. You can add and maintain various types of contracts, such as service contracts and lease contracts.
