User Defined Attributes
User Defined Attributes (UDAs) enables the system administrator to add new attributes to any element in the databases of a project. These UDAs are created as elements in the LEXICON database inside the project. Because LEXICON databases are project specific, it is possible to define attributes to suit individual project requirements.
Once defined, UDAs may be accessed in much the same way as normal attributes, including setting values, querying and reporting upon these values. Utilities such as the Data Output and Project Reconfiguration functions treat UDAs as they would other attributes. UDAs can also be used in expressions.
