I pulled this out of the help text several years ago, There may be more colors now.
Visual Integrator Import Field Color Meaning
This list box displays fields from the data file selected on the Configuration tab. The fields are color-coded as follows:
- Fields that appear in blue are required fields.
- Fields that appear in cyan are required fields that have dictionary default values assigned to them as a starting point for a new job.
- Fields that appear in magenta are conditionally required fields and are validated at the time the record is written. These fields cannot be validated during a test import.
- Fields that appear in black are not validated; however, these fields may be required (for example, numeric fields for quantity or price).
- Read-only fields will be displayed in red in Import Job Maintenance
All required fields must be selected for import. User-defined fields are listed at the bottom of this list box with a UDF_ prefix.
