Selecting
Email Key fields
When
you select an E-mail Key Field for a particular level, a special
index is added to the database on that level.
In Key Field Preferences, TeleMagic will not allow you to select
an E-mail Key Field from a higher level. Because cross-level indexes
are no longer allowed, this can result in an invalid index being
created. To avoid this, make sure the field you select for the
E-mail Key Field on each level is from the currently selected
level.
