Hello, I have the following problem. I have two systems that generate a CSV file with embedded data. And the problem is that two fields contain the information of the name of my supervisors and when it comes from the source it would be the Supervisors_A field: "supervisor name" and then Supervisors_B in that row the situation is: "N/A" and vice versa. How can I solve to have a single one with all my supervisors and eliminate the N/A. Thanks, I have tried grouping them as generic fields and it gives me an error.
