问题
In Power BI I have some duplicate entries in my data that only have 1 column that is different, this is a "details" column.
Name | Value | Details
Item 1 | 10 | Feature 1
Item 1 | 10 | Feature 2
Item 2 | 15 | Feature 1
Item 3 | 7 | Feature 1
Item 3 | 7 | Feature 2
Item 3 | 7 | Feature 3
I realize this is an issue with the data structure, but it cannot be changed.
Basically, when I sum up my Value column on a Power BI card, I only want it to sum for each unique name, so in this case:
Total = 10 + 15 + 7
I will be using the details in a matrix, so I cannot simply remove the duplicates from within the Query Editor.
Is there any way I can filter this with a DAX formula? Just summing the first occurrence of an item?
回答1:
You can create a measure as follows:
Total = SUMX(DISTINCT(Data[Name]), FIRSTNONBLANK(Data[Value], 0))
It will return the first non-blank Value for all distinct Name and sum it up.
