Data Transformation port <port name> not found in the group <group>.
The Data Transformation service is returning data to ports that you defined on the Relational Hierarchy tab of the Unstructured Data transformation. A port is missing from one of the groups on the tab.
When you define hierarchical output groups in the Unstructured Data transformation, you must define the same structure in the Data Transformation project. To change the Data Transformation project, export the group hierarchy schema file from the Unstructured Data transformation. Import the schema to the Data Transformation project and recreate the project.
