How can I fix this Beast Mode Window Function to display the proper value in the total row?

I have the following table that is using window functions in beast mode to calculate pipeline coverage.

I have these window functions for calculating the visible visible columns:

Pipeline/AOP
SUM(CASE WHEN LEFT(`Stage`, 1) != '7' THEN `Pipeline` END)
/
MIN(`AOP`)

OVER (PARTITION BY `Selling Lane`)
Late Stage/AOP
SUM(CASE WHEN LEFT(`Stage`, 1) IN ('3','4','5','6') THEN `Pipeline` END)
/
MIN(`AOP`)

OVER (PARTITION BY `Selling Lane`)

Each Selling Lane has a specific AOP and there are multiple records for each selling lane.

The issue is the total row is showing the sum for each of the Selling Lanes' coverages instead of the total aggregation. I'm assuming this is because I have the partition by clause included in there, which is needed to calculate it for each selling lane. Is there a way that I can get the total row to show the aggregate overall instead of the sum for each of the selling lanes?

    The total row adds everything after beast modes have been applied. You’ll need to stack your data in an ETL using an append with your data set grouped and summed and call the rows TOTAL. Then you can use the beast mode to calculate your data for each lane and the total

    I don't quite understand what you're trying to accomplish, but this is syntactically incorrect (for analyzer) ... it's fine for standard SQL. But this window function MIN(AOP) will not aggregate as expected.

    SUM(CASE WHEN LEFT(`Stage`, 1) IN ('3','4','5','6') THEN `Pipeline` END)
    /
    MIN(`AOP`)
    
    OVER (PARTITION BY `Selling Lane`)
    


    Window functions in Analyzer must always include two aggregations b/c the windowing happens AFTER the initial GROUP BY clause is applied.

    In the below example, by taking SUM(AOP) for each row of your displayed axis, and then taking the MIN of each SUM() you're finding the minimum aggregated AOP across all your rows.

    If you did it the other way around SUM(MIN(AOP) you'd find the minimum AOP for each group and then sum the MIN(AOP) across all groups.

    SUM(CASE WHEN LEFT(`Stage`, 1) IN ('3','4','5','6') THEN `Pipeline` END)
    /
    MIN(SUM(`AOP`)) OVER (PARTITION BY `Selling Lane`)

    Did you try this?

    SUM(CASE WHEN LEFT(`Stage`, 1) != '7' THEN `Pipeline` END) OVER ()
    /
    MIN(`AOP`) OVER(PARTITION BY `SF Selling Lane`)

    Thanks for your response! Unfortunately that seems not to have worked. Doing that breaks the aggregation by selling lane and shows the overall aggregation * number of records in the total row.
