Lookup Transformation <transformation name> has no associated Partial Pipeline. No single group Source Qualifier of name <Lookup table name>. Transformation is not valid.
The Pipeline Lookup transformation is not valid because there is no valid partial pipeline to lookup. The partial pipeline does not have a single group source in the Source Qualifier for a lookup. Therefore, the Lookup Table Name attribute in the Pipeline Lookup transformation does not match the Source Qualifier name in the partial pipeline.
Verify that the partial pipeline is valid and has a single group source in the Source Qualifier for the lookup.
