System data definitions are predefined in the Emptoris® Contract Management application.
System data definitions are used to supply standard fields to the standard line definitions. System data definitions cannot be changed.
System data definitions also include any custom property data definitions that are created while defining an external organization custom property.
You can create user-defined data definitions to be added in line definitions.
For a list of system data definitions, see Standard Line Definitions. The names of line definitions are the same as data definitions that are available in the system.
