The Look Up column shows whether a field can be used for a lookup against the Data Source and is only valid for Top Level Objects. A number will also be shown in brackets, which indicates the order of fields when a Data Source lookup is performed on a client device.
To enable a Look Up on a field, select a value from 1 to 6 in the edit field settings menu. The number 1 indicates it is the first field that you would like to be displayed when a Look Up against the Data Source is performed.
