Specifies how dimensions can be used together, such as in a journal or a document. A company may wish to control the way in which dimensions are combined on an entry. By defining combination restrictions, you can select whether dimension combinations can be used in all circumstances, only in some circumstances or not at all.
This is useful if a company has business rules about what information can be combined on an entry, for example, that users may not post invoices when they have attached both a department dimension and a project group dimension to an entry. You can also restrict the use of a particular dimension combination, dependent on which dimension value combination is being used for the two dimensions.
