Hi Experts

What is the best approach to get the maximum value of a number type column in lists using the SharePoint connector?

I have tried the following.

The first one works but gives warning that it may not work on large datasets.

Set(VarPlanID,Max(RTR_WorkOrders,WorkOrder));

The second one works sometime and sometimes it doesn't.

Set(VarPlanID,First(Sort(RTR_WorkOrders,WorkOrder,SortOrder.Descending)).WorkOrder+1);

Could you experts please enlighten me on the best approach to get this done without overheads?

This list has 10k rows and grows 5k per year

Hi @bkshemeer ,

Generally, we use the second method to get the largest number in a list column. However, if the list includes huge amount of data, it may also get incorrect result. For this case, you can call a flow in your App and get the result.

In PowerApps:

Set(VarPlanID,Flow.Run().WorkOrder);

Best regards,
