DAX Error:The PARTITIONBY function can only be used in the PartitionBy parameter of window functions

[Nathan__Mox]

Hey all,

Im having a bit of trouble with the Power BI DAX calculation below.

Expected result CC =
SUMX (
    WINDOW (
        1,
        ABS,
        0,
        REL,
        SUMMARIZE ( Data, Data[Item Code], Data[date], Data[Quantity] ),
        ORDERBY ( Data[date], ASC ),
        KEEP,
        PARTITIONBY ( Data[Item Code] )
    ),
    Data[Quantity]
)

It works perfectly on my device, but when I share a copy to someone else it come up with the error 'The PARTITIONBY function can only be used in the PartitionBy parameter of window functions.' 

I'm unsure if this is a problem with Power BI or our devices.

Any help would be very much appreciated!

Any extra infomation let me know.

Thanks 

Nathan

The first thing I'd check is if their version of Power BI is up to date.
