fferpcore.DataTransformationServiceglobal with sharing class DataTransformationService Perform data transformation using the Transformation Tables. Methodstransformglobal static fferpcore.DataTransformationService.TransformResult transform(Set<fferpcore.DataTransformationService.TransformRequest> requests) The method takes a set of TransformRequests and performs the transformation.
