Subtotaling with SUMX and Summarize

[dsandberg]

I am attempting to subtotal a column using an approached defined in this post. But, despite my best efforts, my subtotal calculation is not returning what I expect. In my report, I am using the matrix visual and I'm stacking a field number (Fld_Number) and then the report number USDA[Report.Number].

I expected my [Weighted 6oz] column to report the same row level values as the [raw x factor] column.

Weighted 6oz = 
SUMX (
    SUMMARIZE (
        USDA,
        USDA[Report.Number], 
        "RESULTS", [raw_6oz_pct] * [Factor]
    ),
    [RESULTS]
)

I had intended the DAX formula below to show a subtotal of .664 (66.4%). However, I'm not seeing the row level data showing correctly, nor am I getting the subtotal to act correctly.And... the more puzzling thing is that I did have it working correctly, but something changed and I cannot figure out how to re-code my statement to make it work!

Can anyone offer any ideas on how to achieve what I'm after?
