It checks if the sum of Object ID is larger than 1. I have no idea where in the qlikview chart the condition is used, so I have no idea what effect it has on the chart. And that also makes it impossible to tell how to achieve the same in Qlik Sense.
The condition is satisfied when the sum of Object ID is larger than one. You should be able to check in your data if the is a field Object ID and if that field contains numeric values that can be summed and add up to more than 1.
