Formula Column Data Type Choice - nested if

Report

Posted on by TTPlayer

I have a formula column of data type choice. If I write a simple condition everything works. For example:

If(Name = "Test",
    Unterlagenstatus.'liegt vor',
    Unterlagenstatus.'liegt vor'
)
 

As soon as I add a second condition I get an error message:

If(Name = "Test",
    Unterlagenstatus.'liegt vor',
    If(Name = "Test",
        Unterlagenstatus.'liegt vor',
        Unterlagenstatus.'liegt vor'
    )
)
 
Error: The operation cannot be performed on multiple Option Sets. Please use single Option Set as result type.
 
If I convert it as follows, the error doesn't occur.
 
If(Name = "Test",
    If(Name = "Test",
        Unterlagenstatus.'liegt vor',
        Unterlagenstatus.'liegt vor'
    ),
    Unterlagenstatus.'liegt vor'
)
 
Can someone explain to me what I'm doing wrong? Or is this a system error?

have you tried using switch? your second if condition doesn't seem to fit in the way "If" works in powerapps which is just a sequece of condition1->result1, condition2->result2

If( Condition1, ThenResult1 [, Condition2, ThenResult2, ... [ , DefaultResult ] ] )

Thank you for your reply. I managed to create my formula correctly in another way.
But I still don't understand the problem. Why doesn't the above example work?

The following variant works. If I use choices instead of text, I get the error above. Why?

If(Name = "Test",

"A",

If(Name1 = "Test",

"B",

"C"

)

I just ran into the same issue, and changing to the format of "if" suggested by Shashank Bhide worked for me with a Choice.

I think the issue with the nested "if"s is that the return value of the inner if is a Yes/No - so the return value is then a mix of your Choice and Yes/No, rather than always your Choice.
