BO field mapping (customized)
General
This can be used to configure how certain (user-definable) field values are mapped to and from an external system.
For the external field mapping, the following mapping types are available:
External code – BO definition (refers to a BO, so typically used to create a certain UdBO)
External code – Boolean (refers to an External Business object field definition that is (based on the value of the External code) either Yes or No)
External code – No mapping (External Business object field definition that can be completely consumed or provided to the external system)
External code – Code mapping (External Business object field definition that can only be consumed if there is a mapping available in the External BO Code mapping)
Behavior
Navigation: the selected externally managed BO definition will be auto-populated after selecting a business object.
The BO definition (externally managed) reference is not cleared in the popup when the Mapping type field is changed.
The selected field definition BO in the previous step can be auto-populated when navigating to the BO field mapping (customized) level and creating the new mapping.
The External business object - field definition popup contains all the field definitions associated with the Planon external business object definition field selected at the BO configurations (externally managed) level.
When the External business object - field definition field is selected, the Planon external business object definition field is read-only.
When the External business object - field definition field is not filled, the Planon external business object definition is editable.
