Data Transformation group <group> not found in the Unstructured Data transformation.
The Data Transformation service is returning data to groups of ports that you defined on the Relational Hierarchy tab of the Unstructured Data transformation. A group is missing from the Unstructured Data transformation.
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.
