| object node type (CA-MDG) |
A global identifier for a semantically related set of attributes of an object. For example, S180 is the object node type for the object node Financial Accounting Chart of Accounts and S189 is the object node type for the object node Financial Accounting Chart of Accounts Item. In key mapping, only object identifier types that share the same object node type and belong to the same business object type can belong to the same mapping group.
