Purpose

There are a number of reasons for modifying a relationship in an extension, including: 

• Changing the status of the relationship from active to inactive, or from inactive to active
• Changing the relationship group of a specific relationship
• Changing the characteristic type of a relationship

Principles

Relationships that are used to define extension concepts can be modified. However, please note that only the values of mutable attributes may be modified. As indicated in , the six mutable attributes of a relationship are: effectiveTime, active, moduleId, relationshipGroup, characteristicTypeId, and modifierId. When a change is required to the source, destination or type of the relationship, the relationship must be inactivated and a new relationship created with the required values.
