Weighted Average
Hello,
I need to compute a weighted average for the consumer price.
Currently, CP YTD is computed as Average(DB(consumer price). However, if I use this formula I receive an arithmetic average.
I need to weigh the consumer price for NES YTD (Sales).
the formula needs to be something like: (CP YTD*NES YTD)/sum(NES YTD). however, I need to do that for each level.
for example:
for liv6 [(NES Ytd 541... * CP YTD 541... )/ sum (NES YTD 541... + NES YTD 541... and so on) ]
the denominator needs to be dynamically adjusted depending on the level that is analysed.
How can I do that in DAX?
Thanks for the help
Try to use the sumx function.
WA = VAR total_ = CALCULATE( [NES YTD], ALL(xxxxx) ) VAR _Table = ADDCOLUMNS( SUMMARIZE( Sales, xxx[Row1],xxx[Row2] ), "nes", [NES YTD], "cp", [CP YTD] ) RETURN SUMX( _Table , [cp] * [nes]/total_ )

Thanks for your reply!
I have just some further questions?
- What do you mean with xxx?
In Var total_ do I need to insert the name of the table? - in Var _Table is sales a new or existing table?
- What do Row1 and Row2 refer to?
I really appreciate your help!

It refers to the column name of row labels. If the problem still exists, Please provide some sample data, preferably a pbix after removing sensitive data.
