#MULTIVALUE error in WEBI crosstab

Hello Experts,

I am using cross tab in a webi report and I get multivalue error in WEBI

When I select the table property "Avoid Duplicate row aggregation", I get the below result

As you can see, that in the first image, the Actual cost is calculated correctly, but the Quantity, is anot able to add up and gives multivalue error.

Please help resolve.

Thanks
