Adjusting Field Attributes
in AXIS Users Guide - Basics of Table Definition

There are three main attributes associated with each field in a table, which are indicated beside the field names in the list of fields in the Field Definition window. These are:

Field Attribute Values Meaning
1. * M - Mandatory always predefined (according to module)
  O - AXIS optional field predefined fields which may be added to a table (often used for fields sent to AXIS cells with each record)
T - AXIS optional table predefined table which may be linked to each record or cell to be exported
U named and defined by user (may not be exported directly to AXIS cells)
2. Fld Source Input loaded from source File
  Calculated generated according to user specifications after loading
Default allows set value to assigned to this field for all loaded records
3. Fld Type Alpha text field (alphanumeric data)
  Numeric numbers on which computations can be performed


The field name and type in a mandatory or optional field are predefined and may not be changed by the user. You can, however, change the source of a mandatory field - calculating it, loading it from a source file or setting it to a default value.  A user defined table, on the other hand, may have its name, type, and source attributes redefined at any time although changing the type may be disallowed if the field is included in a mapping process. 

To edit a field name, field source, or field type, select the field from the field definition window and click on the Properties button at the bottom of the window to bring up the main tab of the field properties window.  

Selecting the appropriate source attribute for each field is an important step to perform immediately after adding new fields to the table, as subsequent steps in the field definition basically relate to defining the loading process, which defines the input fields based on the contents of the source file, and the mapping process, which is the primary way to defined calculated fields.
