Unable to add Variables to a report if it is a dot-walked field.
Steps to Reproduce
Create a report on the sc_task table or database view sc_task_sla.
From the Available list, find Request Item [+], and expand it to dot-walk to sc_req_item.
Find Variables [+] and expand it.
In the pop-up window, select any variables from the list and add it to the selected list.
Run the report.
The selected variables do not show in the report columns.
Create a report on sc_req_item, and perform same actions.
Variables show up correctly in the report column.
Report against the table directly.
