DAX GROUP BY error - Couldn't load the data for this visual

[emilypoon]

Hi,

I want to put a DAX measure into Power BI desktop but I got an error message as follow:

My DAX expression as follow:

test_teu = GROUPBY(OrderedItemSummaryBI,OrderedItemSummaryBI[ShipmentContainerNumber],"test_teu",AVERAGEX(CURRENTGROUP(),OrderedItemSummaryBI[ContainerTEU]))

The idea of the formula is to calculate the average ContainerTEU for each ShipmentContainerNumber.

So, I tried to used GROUPBY to aggregate the ShipmentContainerNumber and calculate the average ContainerTEU for each of the ShipmentContainerNumber.

The final product I want to have is to sum up the total of the "Average ContainerTEU" for all the ShipmentContainerNumbers.

Is there anything wrong with the formula or if anything was missing?

Thank you!

Best regards,

Emily

Hi @emilypoon,

Based on this document, it says that Group by returns a table, not a scalar value. 

"Return Value:  A table with the selected columns for the groupBy_columnName arguments and the grouped by columns designated by the name arguments."

This is exactly what this error message is saying.
