Help with new column

[mikejmurphy7]

I need to create an extra column in my table that populates the reason code which is 81 into the Type 1 New column, seems very straight forward but can anyone help

 

Booking ID	type	Reason Code	New Column
49265	1		81
49265	2	81

Hi @mikejmurphy7 ,

Please check if this matches your expected output

if [Reason Code]=null then List.Max(Table.SelectRows(#"Changed Type",each [Booking ID]=[Booking ID])[Reason Code]) else null
