Attribute Binding
Info
Method name: AttributeBinding
This implementation will apply value of an attribute to a field.
Typical use case example: when there is any pricing logic based on a field bound to an attribute use this pricing plan step to populate the value (as OOTB attribute binding mechanism will not work here).

Use
To configure populating value for attribute:
- set target field and source attribute:
"MyField__c" : "ATTR_MY_ATTRIBUTE"
