This window displays all of the field definitions for a particular segment. The user can see the field # (1-nn), the maximum size allowed in that field (according to HL7), the HL7 Data Type, and, if applicable, the HL7 table ID that relates to the particular field element. The item ID field is an optional numeric field that can be used for whatever purpose you need, but is intended as a reference to an area of the official HL7 document (or the vendors specific HL7 Implementation Guide) that defines the element. The 'Flag' field is a user-defined field to draw attention to the field. This field is set automatically to true if annotations are added to the element (but it is not automatically set back to false if annotations are removed).
In edit mode (as shown below) you can edit all of the fields in place. To add a new field the 'New' row at the top of the list is used to enter the new field values and press the 'Enter' key on the keyboard to commit changes to the list. Whenever modifications are made to any fields (or new fields are added) a 'Save Changes' button will appear to permanently commit those changes to the vendors definition files. To delete an element, highlight the element by clicking on the leftmost column (left of Field #) and press the 'Del' key on the keyboard.
From this window you can click 'View HL7 Tables' to open the HL7 Table Definitions window. If there is a tableID > 0 for the currently selected element, that table will automatically be selected when the tables window opens.
You can also click 'View HL7 Data Types' to open the Data Type Definitions window, the data type of the currently selected element will automatically be selected.
Click the 'Properties' button to view / edit extended element properties.
