Sum of values within multiple columns based on disconnected slicer table

[hnguyen76]

Hi All.

I have a disconnected table that I'm using as a slicer and then I have this fact table that's wide rather than long. Sadly, it is not possible for me to unpivot the data as I have no control over any of the data modeling aspect. However, what I need to do is to be able to sum up the amounts based on my slicer values.

My disconnected slicer table has these values:

ID	Value
1	ABC
2	DEF
3	XYZ

While my fact table has a sample data of:

Date	ABC	DEF	XYZ
1/1/2020	100	200	400
2/1/2020	200	400	800
3/1/2020	300	600	1200

So within my slicer, if I select for example, ABC and XYZ the return that I'm expecting would be this (do note that this should still be disconnected):

Any help would be greatly appreciated!

@hnguyen76 , Try a measure like

if(maxx(filter(allselected(Table1), Table[Value]="ABC"),Table1[Value]), Sum(Table2[ABC]),blank())
+if(maxx(filter(allselected(Table1), Table[Value]="DEF"),Table1[Value]), Sum(Table2[DEF]),blank())
+if(maxx(filter(allselected(Table1), Table[Value]="XYZ"),Table1[Value]), Sum(Table2[XYZ]),blank())

unpivot will be the best option, If possible

@amitchandak  Nice! I had to make a small adjustment but the idea is a good start!

Measure = 
    IF(CONTAINS(FILTER(ALLSELECTED(Slicer), [ID] = 1), [ID], 1), SUM('Fact'[ABC]), BLANK()) 
+   IF(CONTAINS(FILTER(ALLSELECTED(Slicer), [ID] = 2), [ID], 2), SUM('Fact'[DEF]), BLANK()) 
+   IF(CONTAINS(FILTER(ALLSELECTED(Slicer), [ID] = 3), [ID], 3), SUM('Fact'[XYZ]), BLANK())

Just taking your idea, I built this a bit further to get the same results but still not as .. dynamic as I would like it. Think it is ever possible to make it any more future-proof?

A_Bit_More_Streamlined = 
VAR _Values = VALUES(Slicer[Value])
VAR _Tbl = 
GENERATE(
    _Values,
    ROW(
        "SUM",
        SWITCH( [Value],
            "ABC", SUM('Fact'[ABC]),
            "DEF", SUM('Fact'[DEF]),
            "XYZ", SUM('Fact'[XYZ])
        )))

RETURN

SUMX(_Tbl, [SUM])

Hi @hnguyen76 ,

You can unpivot even if the table is wide. You can try selecting the Date column and selecting Unpivot Other Columns. When your table has a new column need to be added, and the Power BI will automatically complete the unpivot.

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
