+### Update variables using data links
+
+Data links help expose additional functionality of the Business Table. Changing a variable through the table can be implemented as follows.
+
+Configure the Data Links option
+
+```
+/d/${__dashboard.uid}?${__url_time_range}&var-Test=${__data.fields.device}
+```
+
+where `__data.fields.device` uses the value from the `device` field in the current row when the cell is clicked. This is how the variable will be changed. In string `var-Test` the substring `Test` is the variable to be replaced.
