Hello, I am learning BI Desktop, but the Add Conditional Column dialog box has some issues, as described below 1. When I reopen the dialog box, the (first 2 of 3) Operator Values that I selected are not there. The other values on the row are there. 2. Pressing the Delete key in a Value field, deletes the row. To me, the Delete key should delete the value that I typed in the Output field. 3. How do you check for a null value in a date field? I tried typing in null in the Value field and also tried leaving the Value field empty, neither worked. I also tried using the Otherwise fields Enter a value option, thinking it would work as a catch-all, that didn't work either.
