Error: Comparison operations don't support comparing values type Text with Values of Type Number

[Anonymous]

Hi, 

I'm new to DAX and need some help, I'm creating a measure in a tabular cube in SSAS. I need to retreive the LastYearLastWeek data from x column:

LastYearLastWeek:= CALCULATE([x], FILTER(ALL(Time), Time[WeekNumber] = SELECTEDVALUE(Time[WeekNumber]) -1 && Time[Year] = SELECTEDVALUE(Time[Year])-1))

But I get this error in the syntax: comparison operations don't support comparing values type Text with Values of Type Number. Considering using VALUE or FORMAT functions to convert one of the values. 

Fields used: WeekNumber and Year from Time table are whole numbers.

It doesn't really make sense to me, any tips on how to fix it? 

Also maybe there is a better way to get LastWeekLastYear, do you know of any? 

Thanks

Hi @Anonymous ,

Since the error pointed out that it was a data type issue, could you double check the data type of Time[WeekNumber] and Time[Year] columns? Or, if the expression works with "VALUE" function, the data type of the two columns is indeed text.

LastYearLastWeek :=
CALCULATE (
[x],
FILTER (
ALL ( Time ),
Time[WeekNumber]
= VALUE ( SELECTEDVALUE ( Time[WeekNumber] ) ) - 1
&& Time[Year]
= VALUE ( SELECTEDVALUE ( Time[Year] ) ) - 1
)
)

Then, is [x] a column or a measure? If it is a column, it may need to use SUM, MAX, etc, functions with [x].

Best Regards,

Hi

i m trying to extract first X digits out of my ID column of data as

Match-ID = IF('ATL-270524'[NTN-FBR] = 9, LEFT('ATL-270524'[NTN-FBR], 7), LEFT('ATL-270524'[NTN-FBR], 11))

but this resulted in error as "DAX comparison operations do not support comparing values of type Text with values of type Integer. Consider using the VALUE or FORMAT function to convert one of the values."

basically the field "NTN-FBR" is having digits plus "-" dash in few cases that is why i've kept data type of this field as "TEXT"

kindly guide ASAP.
