DAX for SWITCH statement on calculated column - how to include VALUE function?

[philippa_f]

Hi

I have a calculated column in my table that works out number of Days to Expiry, and I then need another calculated column to allocate descriptors based on that number to give me 'Expiry Status'. I am trying the following:

Expiry Status = SWITCH(

TRUE (),

'MyTable'[DaystoExpiry] = "", "No Exp. date",

'MyTable'[DaystoExpiry] < 0, "Expired",

'MyTable'[DaystoExpiry] > 366, "Exp. date > 1 yr",

"Exp. date <= 1 yr"

)

But this gives me an error message that: 

DAX comparison operations do not support comparing values of type Number with values of type Text. Consider using the VALUE or FORMAT function to convert one of the values. 

I have checked DaystoExpiry and the data type is Decimal number. Some are blanks, which is expected. How can I fix this with VALUE or FORMAT in my DAX?

Thanks everyone for trying to help. I have just got it to work using the following:

Expiry Status =

SWITCH (TRUE(),

'MyTable'[DaystoExpiry] =BLANK(), "No Exp. date",

'MyTable'[DaystoExpiry] < 0, "Expired",

'MyTable'[DaystoExpiry] < 366, "Less than 1yr",

'MyTable'[DaystoExpiry] > 365, "More than 1yr"

)

I think the issue was the order of my logic, together with using "" when I should have been using BLANK().

Got there in the end with your combined help 🙂

Hi,

Try following code.

Expiry Status =

VAR NoofDays = SUM(MyTable[DaystoExpiry])

RETURN

SWITCH(TRUE() ,

NoofDays = 0, "No Exp. date",

NoofDays < 0, "Expired",

NoofDays > 366, "Exp. date > 1 yr",

"Exp. date <= 1 yr"

)

Thanks

Hi AUDISU

Thanks. I tried this, but it gives a result of 'Expired' for every line of data, although there are definitely some that should be in each category. Any idea what I am doing wrong? Data type is text, if I change it to numbers I just get an error for everything, with a message saying Cannot convert value 'Expired' of type Text to type Integer.

I really appreciate you taking the time to help with this.

Hi,

Share the link from where i can download your PBI file.

Sorry! I can't do this as it's private organisational stuff 😞
I will try to create a dummy anonymised version though.

Hi Philippa,

Can I see your DAX formula?

Thanks

[philippa_f]

Sure:

Expiry Status =

VAR NoofDays = SUM('MyTable'[DaystoExpiry])

RETURN

SWITCH(TRUE() ,

NoofDays = 0, "No Exp. date",

NoofDays < 0, "Expired",

NoofDays > 366, "Exp. date > 1 yr",

"Exp. date <= 1 yr"

)

Hi Philippa,

Please check data type of 'MyTable'[DaystoExpiry] column.

If it is not in number format change it to number.

Thanks

Kindly check the datatype of "'MyTable'[DaystoExpiry]"

When you are calculating null/blank values for MyTable'[DaystoExpiry] it is better to return BLANK not "" which causes to enforce column to Text datatype.

Hi FarhanAhmed

Thanks so much for getting back to me. I did substitute BLANK in the code above instead of "" - was this what you meant?

Like this: 

Expiry Status = SWITCH(

TRUE (),

'MyTable'[DaystoExpiry] = BLANK, "No Exp. date",

'MyTable'[DaystoExpiry] < 0, "Expired",

'MyTable'[DaystoExpiry] > 366, "Exp. date > 1 yr",

"Exp. date <= 1 yr"

But it is still not working, giving me an incorrect syntax error.  Can you spot what I have done wrong? Many thanks in advance!
