Thank you very much for the answer but I do not know how to apply it because it asks me for the name of the table and auque I indicate it I get the following error: Unexpected error in the query 'FnDetectAndTransformTypes'. Expression.Error: The import SourceTable matches no exports. Did you miss a module reference?
