Simple if-then statement DAX
Hi guys,
Can I get help with a quick, if-then statement, with the following criteria?
If flight # = 832, flying on Tues, Wed, Thurs, and Fri (Days 2, 3, 4, 5), then seats = 53.
I have this, and am getting an error of "token literal expected:"
if [#"Flight #"]="832" && ([Day of Week]=2 || [Day of Week]=3 || [Day of Week]=4 || [Day of Week]=5) then [Seats]="53" else 0
Can't seem to figure out my error.
Hi LearningBI1986 ,
Ok. Based on the error you're getting, it looks like you're trying to do this in Power Query. If so, then it's not DAX you need, it's M, and you appear to have mixed both languages in your statement.
The if..then structure in M looks like this:
if (something and somethingElse) or anotherThing then doThisThing else doThisOtherThingSo, your example would look something like this:
if [#"Flight #"]="832" and List.Contains({2,3,4,5}, [Day of Week]) then 53 else 0Pete
Hi LearningBI1986 ,
Pete provides m-codes that you can use in the PowerQuery editor to add a custom column.

For DAX, please try:
Seats = IF( 'TableName'[Flight #] = 832 && 'TableName'[Day of Week] IN {2,3,4,5,6}, 53, 0 )Best Regards,

Thank you! I am fairly new to this, so I understand what you are saying now. Thanks again.
