Extracting unique values with a condition

[SecretChimpanze]

Hi,

I have a column with text that looks something like this:

Fixed-Fixed-Postpaid-Fixed-OMB-OMB

Is there a formula that will return only unique values in between the dashes (-)? 

Required: Fixed-Postpaid-Fixed-OMB

Hi @SecretChimpanze 

please try

NewColumn =
VAR String = TableName[ColumnName]
VAR Items =
    SUBSTITUTE ( String, "-", "|" )
VAR Length =
    PATHLENGTH ( Items )
VAR T1 =
    GENERATESERIES ( 1, Length, 1 )
VAR T2 =
    ADDCOLUMNS ( T1, "@Item", PATHITEM ( Items, [Value] ) )
VAR T3 =
    DISTINCT ( SELECTCOLUMNS ( T2, "@@Item", [@Item] ) )
RETURN
    CONCATENATEX ( T3, [@@Item], "-", [@@Item], ASC )

Thanks for this. Can I use this code via "New Column"? I did that and got this error 

"The arguments in GenerateSeries function cannot be blank"

Hi @SecretChimpanze 
Apologies, I was outside the office when I shared the solution. 

Yes this is a calculated column but its seems that you have some blank cells. Just modify as follows.

NewColumn =
VAR String = TableName[ColumnName]
VAR Items =
    SUBSTITUTE ( String, "-", "|" )
VAR Length =
    COALESCE ( PATHLENGTH ( Items ), 1 )
VAR T1 =
    GENERATESERIES ( 1, Length, 1 )
VAR T2 =
    ADDCOLUMNS ( T1, "@Item", PATHITEM ( Items, [Value] ) )
VAR T3 =
    DISTINCT ( SELECTCOLUMNS ( T2, "@@Item", [@Item] ) )
RETURN
    CONCATENATEX ( T3, [@@Item], "-", [@@Item], ASC )

Thank you so much, you have made my day/week/month! I have been scouring the internet for almost a week and have not been able to find a solution.

@SecretChimpanze , In Power Query Refer TextBetweenDelimiters, Also use relative position

This is what I need but unfortunately I am unable to use this method as mine is a calculated column
