Hello Anonymous 

 

Thank you for your reply.

 

Below you can find a shorter version of the Shipments table and a screenshot of my data model.

 

The screenshot found at my initial message shows the results filtered to the status RU.

    The only difference is with the field PreviousDataSet  and OldestDataset.

    I would build two tables using Week + PreviousDataset and Week + OldestDataset. Then, you can compare where the difference is.

    When you filter the Week from the Date table, it will filter the Shipment table. So maybe, when the rows are filtered, sometimes, you will have 3 dates with 3 index so in this case MAX( Index) and Current+1 won't return the same value. 
    If Current is 1 then MAX( Index) will return 3 and the other one 2.

    HI Anonymous,

    If these expressions get the same result when you use static values and get different results when you add aggregate functions to let them dynamically based on current row contents.
    For this scenario, it means these functions are working on the different row context levels so that the min/max function got the different results and they affect expressions calculations.

    Please take a look at the following blog about row and filter context if help:
