Check if substring from column exists inside string in another table column

[Mourad_Analyst]

I have two tables, firstone identifiants, which has id column as below :

second table informations, which has information id column as below:

I added a custom column check in identifiants table to check if id exists (TRUE) or not (FALSE) in information id column in informations tabe.

please what's the solution for that?

Hi @Mourad_Analyst ,
to my understanding of the problem, it seems to work alright (as the fields in information id don't seem to match those of the id column.
So maybe my understanding of the problem is incorrect. 
Could you please upload sample data in a way so that it can be used to provide a correct answer:

Also, please indicate what result exactly you expect for reach row of the sample data.

Agreed with this. Please provide some sample data and a sample output as to what you're expecting to accomplish. That will allow us to see things more clearly

Hi @Mourad_Analyst ,
could you merge the informations table on "information ID" and then instead of expanding the resulting table, add a column with the formula "not Table.IsEmpty[MergedColumnName]".

@Mourad_Analyst Use this:

AddedCustom = 
    Table.AddColumn (
        ChangedType,
        "Custom",
        ( CurrentRow ) =>
            List.AnyTrue (
                List.Transform ( 
                    identifiants[ID], 
                    (ID)=> Text.Contains ( CurrentRow[information id], ID ) 
                )
            ),
        Logical.Type
    )

@Greg_Deckler , correct me if I am wrong but I dont believe Text.Contains will work on its own as it doesnt work with a list of values... ?

Perhaps something like this instead: 

=Text.Contains(Text.Combine(informations[informations id]),[id])

[Greg_Deckler]

@Mourad_Analyst Use Text.Contains
