Daily Data but cannot map relationship to show variance day vs day

[MaartenDeuss]

Hi all

Very new to PowerBI, however even our IT guys cannot figure this one out.

I have a date file and each day we get a new data file. I cam trying to compare the two data sets to see what has changed but at an aggregated level.

I have a date table to map date relationship, however when I create a matrix table view, the summation of say today works, but when pulling values from the other table they are a summation of all, not the simlar value as the ist quantity.

Any reason why i cannot get the summary to be the same as "today"?

Hi @MaartenDeuss,

You want to compare the same values from two data tables, right? Since both of two tables have date fields, you could generate an extra date dimention table which lists all available unique dates, then, create a one to many relationship between two data tables and this date table. In Matrix visual, drag [date] field from date diemention table.

Thanks this worked well, I think I was creating the relationship the wrong way round, now you have solved this for me and other issues I was facing.

Thanks so much!!!
