Problem with List.Contains

[jonclay]

Hi everyone

I have a table of contacts that have various Types attributed to them. For example, the Type could be Type A, AA, AAA, B, BB, BBB etc (this is a multi-select field in my Dynamics CRM).

I've created a Custom Field using the List.Contains function as shown below. What I want is to put a 1 in the Custom Field if the contact record contains AA and AAA and 0 if it doesn't.

if List.Contains({"AA,AAA"}, [Type]) then 1 else 0)

This works fine until I have a contact records that has the Type of e.g. AA, AAA, BB (the Custom Fields shows 0).

I assumed (wrongly!) that List.Contains would work if the Type field contained both of the choices (i.e. AA and AAA) no matter what else the field contained (i.e. BB).

So, what I want to acheive is:
Put 1 in the new Custom Field if the Type field contains AA and AAA and any other Type (or not),

For clarity, the following scenarions would result in 1 or 0 as shown:

Type = AA, AAA (field equals 1)
Type = A, AA (field equals 0)
Type = AA, AAA, BB (field equal0 1)
Type = BB, BBB (field equals 0)

How would I achieve this? I'm not wedded to using the List.Contains function if there's a better way!

Many thanks
Jon

Hi @jonclay ,

How about this?

Here the code in Power Query M that you can paste into the advanced editor (if you do not know, how to exactly do this, please check out this quick walkthrough)

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcnTUUXB0dFSK1QGyQUwICyKqo+DkBOY7OYGYQHYsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Type = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Type", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each if Text.Contains([Type], "AA") and Text.Contains([Type], "AAA") then 1 else 0)
in
    #"Added Custom"

In a nutshell, I just used a simple if clause...

Let me know if this solves your issue 🙂

Hi,

This M code works

let
    Source = Excel.CurrentWorkbook(){[Name="Data"]}[Content],
    #"Added Custom" = Table.AddColumn(Source, "Custom", each List.ContainsAll(Text.Split([Type],", "),{"AA","AAA"}))
in
    #"Added Custom"

Hope this helps.
