DAX: Need help to find the 2nd, 3rd delimited values based on string

[Anonymous]

Assume we have the following column called [ERPCode] below. I want to dynamically return the second or third value within my serial key. If my ERP code contains "MI" return the second value, but if my ERP code contains "SI" then return me the third value in my serial key. A sample output is provided for reference.

Please help.

Thanks,

Mohan V.

Hi @Anonymous ,

You just modify the dax formula provided by @Fowmy .

Please try below dax formula:

Column =
VAR _code = [ERPCode]
VAR _len =
    LEN ( _code )
VAR _a =
    FIND ( ".", _code )
VAR _b =
    IFERROR ( FIND ( ".", _code, _a + 1 ), 0 )
VAR _c =
    IFERROR ( FIND ( ".", _code, _b + 1 ), 0 )
VAR _val =
    SWITCH (
        TRUE (),
        CONTAINSSTRING ( _code, "MI" ),
            IF ( _b <> 0, MID ( _code, _a + 1, _b - _a - 1 ), MID ( _code, _a + 1, _len ) ),
        CONTAINSSTRING ( _code, "SI" ),
            IF ( _c <> 0, MID ( _code, _b + 1, _c - _b - 1 ), MID ( _code, _b + 1, _len ) )
    )
RETURN
    _val

Will a Power Query solution work for you?

@Fowmy No, I am looking for dax solution.

Here is the DAX solution, add this as a Calculated Column:

Key = 
IFERROR(
    VAR __EPR = [ERP Code]
    VAR P = LEFT( __EPR , 2 )
    VAR P1 =  FIND("." , __EPR) 
    VAR P2 =  FIND("." , __EPR , P1 + 1 )
    VAR P3 =  FIND("." , __EPR , P2 + 1 )
    VAR RESULT = 
        SWITCH(
            P,
            "MI", MID( __EPR, P1 + 1 , P2 - P1 - 1 ),
            "SI", MID( __EPR, P2 + 1 , P3 - P2 - 1 )
        )       
    RETURN
        RESULT,
    BLANK()
)
