Creating custom column based on other column value

Creating new Custom Column based on other column value. In this case checking if other column is empty or not using the length of the value.

In the Custom column add the code:  each if Text.Length([subrule_id]) > 0 then 1 else 0

in the table colum you will see some different syntax as below: 

Table.AddColumn(#"Changed Type", "subrule_id_flg", each if Text.Length([subrule_id]) > 0 then 1 else 0)

Hope this can help anyone who is working on the similar problem.

Thanks
