Substiute multiple values in a text from another table

[coejnot]

Hi, 

I have this string in a column:

A*B*C*A*C

Then I have this table:

Code	Description
A	Blue
B	Green
C	Red
D	Yellow

I would like to create a column where the result picks the description from the table. 

The result should be like this:

Blue*Green*Red*Blue*Red

I would really appreciate if you could help me with a dax for this.

Thanks!

You can add a custom column in Power Query and achieve the same. File is attached

   Text.Combine(
    List.Transform(
    Text.Split([Column1],"*"),(a)=> Text.Replace(a,a, Table.SelectRows( Table2, (i)=> i[Code] = a)[Description]{0})),"*")
    )

This worked really well, thank you!

@coejnot I realize that this is already solved and @Fowmy solution is the best one. However, I couldn't help creating a DAX solution for this. The solution is based on my Text to Table measure:

Column = 
    VAR __Separator = "*"
    VAR __SearchText = [Column1]
    VAR __Len = LEN(__SearchText)
    VAR __Count = __Len - LEN(SUBSTITUTE(__SearchText,__Separator,"")) + 1
    VAR __Table = 
        ADDCOLUMNS(
            ADDCOLUMNS(
                GENERATESERIES(1,__Count,1),
                "__Word",
                    VAR __Text = SUBSTITUTE(__SearchText,__Separator,"|",IF([Value]=1,1,[Value]-1))
                    VAR __Start =
                        SWITCH(TRUE(),
                            __Count = 1,1,
                            [Value] = 1,1,
                            FIND("|",__Text)+1
                        )
                    VAR __End = 
                        SWITCH(TRUE(),
                            __Count = 1,__Len,
                            [Value] = 1,FIND("|",__Text) - 1,
                            [Value] = __Count,__Len,
                            FIND(__Separator,__Text,__Start)-1
                        )
                    VAR __Word = MID(__Text,__Start,__End - __Start + 1)
                RETURN __Word
            ),
            "__Replaced",LOOKUPVALUE('Table'[Description],'Table'[Code],[__Word])
        )
RETURN
    CONCATENATEX(__Table,[__Replaced],__Separator,[Value])

Hi, @Greg_Deckler 

I tried this out too, and it also works as I expected. 

Interesting to learn even more about how to create things in DAX. 

Thank you!
