## DAX Help With Nested If

Hello

I hope a kind soul may be able to help me out.  I am trying to convert the attached Cognos case statement into a DAX statement, in a caclulated column.  I have been trying for a whole using a mix of if(and and if(isblank and so on but simply cannot get my head around it and hence can't get it written to produce the correct result.

Any DAX heroes suggest a statement that might work pretty please?

Something like this?

Switch ( true ( )

, [field1] = blank() && [field2] = blank() , "double oops"

, [field1] = blank() , "type-1 oops"

, [field2] = blank(), "type-2 oops"

, "Undefined"

)

Or if you want to stay with if please see below. I didn't do exactly the same to yours but used all logical tests you need. Just replace it with your values.

Play with it as it works, just tested it.

fix = if(max(stores[Store name]) = "Aberfeldy", "Aberfeldy store",
if(max(stores[Store name]) = "Abergele", "store",
if(and(max(stores[Store name]) = "Abertillery",max(stores[Store number]) = 173),"warehouse",0)))

Hi @Anonymous ,

Try using a SWITCH() Switch is a link to explanation, and there are a lot of videos out there as well.

SWITCH([Month],
1,"January",
2,"February",
"Some other month"
)

Takes a group of nested ifs and turns it into a readable function. The function stops at the first one that is true.  I always think of it as a penny dropped into a pond, and if there is nothing to stop it (nothing true) then you get the value at the bottom.
Let me know if you have any questions.

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.

Hey Nathaniel

Thanks for your reply - I've been having a play with 'Switch' since you kindly replied but am still struggling.  I think it is the mixture of the AND conditions mixed with me trying to compare where there are potentially blank values that are throwing me.  Also as I am calling different fields in the expression - do I need to nest the switch?  I'm very confused 😞

That seems to have done the trick thank you very much. That pesky double ampersand always catches me out - I was trying to incorporate AND statements but your suggestion seems to have worked. Thank you

Use Switch statement in DAX. It will solve your problem.
