Modifying a CDS Entity's Attributes
Every CDS entity has attributes, which are pieces or sets of data that are associated with that entity. Attributes can reflect or affect the operational behavior of an entity, record the number of times a particular event or problem occurred since the entity was last enabled, and uniquely distinguish an entity for any other entity.
CDS attributes are identified by ISO object identifiers (OIDs). Every CDS attribute name maps to an OID and a corresponding data type. Usually, client applications define the name of an attribute and its data type. Application programmers should never need to modify (except for the purpose of foreign language translation) the existing CDS labels associated with the unique OIDs in the cds_attributes file. However, programmers can obtain new OIDs from the appropriate authority, create new attributes for their own object entries, and then append them to the existing list. The OID and data type of each attribute are stored in the file cds_attributes. Descriptions of the CDS data types that applications can use are in the cdsclerk.h file.
