Expression.Error: We cannot convert a value of type Function to type Number.

[UsePowerBI]

Hello

Any idea why the below results in error?

= Table.RemoveRows(#"Changed Type", each not Text.Contains([A], "some1") and [B]<0)

Expression.Error: We cannot convert a value of type Function to type Number.
Details:
Value=[Function]
Type=[Type]

I do have specified in a previous step [A] to be text and [B] to be integer.

Thanks!

@HotChilli  but the same applies to Table.SelectRows ?

Hi  @UsePowerBI , 

As far as I know "each not Text.Contains([A], "some1") and [B]<0" part works as a function.

As  HotChilli mentioned Table.RemoveRows will use number in second part. 

Table.RemoveRows(table as table, offset as number, optional count as nullable number) as table

Table.SelectRows will use function in second part. So I suggest you to use Table.SelectRows in your code, it will work.

Table.SelectRows(table as table, condition as function) as table

My Sample: 

Result is as below.

M Code:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCs7PTTVU0lEyVIrVgfCMgDxdCNcRJqtrDJc2BnKBvFgA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [A = _t, B = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"A", type text}, {"B", Int64.Type}}),
    #"Remove rows" = Table.SelectRows(#"Changed Type", each not Text.Contains([A], "some1") and [B]<0)
in
    #"Remove rows"

Table.RemoveRows   takes a table and a number as parameters.  The code here passes a function as the 2nd parameter.
