Note: The Graphite Transformation Document is used in all integrations managed by Graphite. For self-managed integrations the transformation document is optional.
The Transformation & Mappings Document describes what fields will be maintained in the ERP when the record is created/updated. Graphite can apply special logic and functions (we call them source expressions) to make these values change depending on other values maintained in Graphite.
The transformation sheet describes templates that form the actual shape of the data that is sent. Generally, this won't need to be modified unless you need to exclude or add whole classes of data such as bank directories, locations etc.
Lookup tables are one-to-one relationships of values that we can use to further transform the data we send to the integration.
