The Invalid Phase Event Types (IPHEVNT) reference page allows the restriction
of what Event Types cannot be used with a Program and Phase combination
as a data entry short cut if there are many more valid Event Types than
invalid ones.
Valid Combinations – This related
page link transitions you to the Valid
Phase Event Types reference page to add, maintain, or review
any invalid records for the Program and Phase. Having records
on both should be avoided because of conflicts and redundancy.
