IF statement with LEN, LEFT & RIGHT formulas

Hello, new to Power Bi, sorry if this is a basic question.

 

I have a column with 2 types of data (lets call it Flight No Colunn) : BA254/BA879 and BA463/548

 

I have created a helper column that returns the length of each cell (11 or 9)

 

I would like to create an if command like this:

 

IF(LEN[Flight No Column]=11, RIGHT[Flight No Column, 5], CONCATENATE(LEFT([Flight No Column], 2), RIGHT([Flight No Column], 5))

 

However, this does not work as I am combining numbers with text in the same formula.

 

Do you have any suggestions?

 

Thank you very much

i only changed the position of the parentheses

Column 2 = IF(LEN(Table1[Flight No Column]) =11, RIGHT(Table1[Flight No Column], 5), CONCATENATE(LEFT(Table1[Flight No Column], 2), RIGHT(Table1[Flight No Column], 3))

Can you provide an example of the output you are looking for in both scenarios (LEN 9 and 11). I ran your code, adding the appropriate () and this is the result:

Thank you for your time. Trying to replicate your code i get this

if (LEN(Table1[Column]) = 11, right(Table1[Column],5), CONCATENATE(left(Table1[Column],2),RIGHT(Table1[Column],3)))

is the correct function

With the above code, I can not go to the second step of the if command as shown here:

I am still failing to write down the correct syntax.

 

Can i kindly ask you to upload your functional Power Bi file?

Can you please share the yellow error message in the screenshot. Also try to copy/paste this :

Column = if (LEN(Table1[Flight No Column]) = 11, right(Table1[Flight No Column],5), CONCATENATE(left(Table1[Flight No Column],2),RIGHT(Table1[Flight No Column],3)))

@NipponSahoreunfortunately your code is not working

 

I can not replicate the working example from @BKirsch12

 

I am uploading my file, would you mind taking a look ?

The error I am getting is this one:

i only changed the position of the parentheses

Column 2 = IF(LEN(Table1[Flight No Column]) =11, RIGHT(Table1[Flight No Column], 5), CONCATENATE(LEFT(Table1[Flight No Column], 2), RIGHT(Table1[Flight No Column], 3))

Yes Nippon is right, the issue is your LEN function needs to return a value before it can be compared to 11.

Thank you both.

 

My final working code is:

 

Column 2 = IF((LEN(Table1[Flight No Column]) =11), RIGHT(Table1[Flight No Column], 5), CONCATENATE(LEFT(Table1[Flight No Column], 2), RIGHT(Table1[Flight No Column], 3)))

The problem is the LEN function. This is what you had in the file you sent:

 

Column 2 = IF(LEN(Table1[Flight No Column] =11), RIGHT(Table1[Flight No Column], 5), CONCATENATE(LEFT(Table1[Flight No Column], 2), RIGHT(Table1[Flight No Column], 3))) 

The length (LEN) function needs to return a value before it can be compared to another number. This is how it should be:  

 

Column 2 = IF(LEN(Table1[Flight No Column]) =11, RIGHT(Table1[Flight No Column], 5), CONCATENATE(LEFT(Table1[Flight No Column], 2), RIGHT(Table1[Flight No Column], 3)))
