M Query - if text.contains specific structure of text

[CR]

Hy guys,

I've 2 tables.

The table1 contains 2 columns: Reference and Description

Ref 1 | 1-TTT-001 - blablabla

Ref 2 | blablabla - 3-XXX-001

Ref 3 | blabla (2-VDF-106) blablabla

The table2 contains 2 columns: Item Code and Item Description.

1-TTT-001  | Item 1

3-XXX-001 | Item 2

2-VDF-106 | Item 3

I would like to be able to know which reference in the table 1 refer to an item of the table 2.

Ref 1 | 1-TTT-001 - blablabla             | 1-TTT-001

Ref 2 | blablabla - 3-XXX-001            | 3-XXX-001

Ref 3 | blablabla blabla                      | null

Ref 4 | blabla (2-VDF-106) blablabla | 2-VDF-106

the point is that the structure of the item code is always X-XXX-XXX. I also think it could be useful but I don't see how to do it in M query.

if Text.Contains([Item Description, something like X-XXX-XXX) then display this thing else null

Do you think it is feasible ?

It would be perfect because I cannot exclude the item codes one y one as I have more than 300 !

Regards,

CR

Hi @CR ,

Try the following code.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCkpNUzBU0lEy1A0JCdE1MDBU0FVIykmEIKVYHYgKI6AKuKiC7qEFxroREREg5XAlxnAlChpGumEubrqGBmaaWMwyASo8tABhGoQ6tEABCR1aoBQbCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [#"Reference " = _t, Description = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Reference ", type text}, {"Description", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each let d = [Description] in Table.SelectRows(#"Table (2)",each Text.Contains(d,[Item Code ]))),
    #"Expanded Custom" = Table.ExpandTableColumn(#"Added Custom", "Custom", {"Item Code"}, {"Custom.Item Code"})
in
    #"Expanded Custom"
