Expressions

 

<IF ONE_TO_MANY>

 

The relationship is a one-to-many relationship and a matching relationship is NOT defined in the opposite direction.

 

<IF ONE_TO_ONE>

 

The relationship is a one-to-one relationship and a matching relationship is NOT defined in the opposite direction.

 

<IF ONE_TO_MANY_TO_ONE>

 

The relationship is a one-to-many relationship and a matching relationship IS defined in the opposite direction.

<IF REQUIRES_MATCH> (deprecated)

 

The relationship requires that matching data must be present in the file targeted by the relationship for the data in the local field to be considered valid.

The relationship targets one of multiple records (i.e. it is a one-to-many or one-to-many-to-one relationship).

 

<IF TO_ONE>

 

The relationship targets a single record (i.e. it is a one-to-one, one-to-one-to-one or many-to-one relationship).

 

<IF VALIDATION_NONE>

 

The ValidationMode property in the Harmony Core Customization file is set to a value of "None".

The ValidationMode property in the Harmony Core Customization file is set to a value of "ValuePresent".
