XQE-MSR-0008 In module <Data Module> the following query subjects are not joined when retrieving more than one table with CADataConnector.read_data

Troubleshooting


Problem

The CADataConnector.read_data method results in an error message when the table_name parameter has more than one table defined.
An example of the table_name parameter:

CADataConnector.read_data(path=".public_folders/Samples/Data Module Test/Orders", table_name=["ORDER_HEADER","ORDER_DETAILS"])
