measure not calculating % correctly

The issue is with the ALL function. Use this corrected measure:

% of Shipment by PickupPerformance by Site =
DIVIDE(
    SUM(TMSShipmentDetail[ShipmentCount]),
    CALCULATE(
        SUM(TMSShipmentDetail[ShipmentCount]),
        ALL(TMSShipmentDetail)
    )
)

This ensures the denominator uses the total shipment count without filters, matching Excel percentages. 

Hi TomSinAA  - check the denominator includes all rows, regardless of filters on any column

use the below measure:

% of Shipment by PickupPerformance by Site =
DIVIDE(
SUM(TMSShipmentDetail[ShipmentCount]),
CALCULATE(
SUM(TMSShipmentDetail[ShipmentCount]),
ALL(TMSShipmentDetail)
)
)

the above logic helps

Hi TomSinAA 

Could you please explain the calculation logic you need and provide relevant example data or table structures(exclude sensitive data) with Text format and your expected result with backend logic and special examples? It would be helpful to find out the solution.
