In the design canvas, select the source that contains the field you want to add to the conditions grid.
The [<Source Name>] window appears, where <Source Name> is the name that appears on the query source node in the design canvas.
In the [<Source Name>] window, in the Fields section, select the field that you want to add to the query.
The field appears in the grid in the Conditions section.
Note: If you add the same field from one source to the grid in the Conditions section twice, you must specify a unique value in the Alias cell for each field. If you do not specify a unique alias, GE Digital APM will add a unique alias automatically.
