Hi @Myusrename001 

You'll want to use a multi-row formula:

1. Group by TX Number
2. Set rows that don't exist to NULL
3. For first row of TX number set to '-' (if previous row is NULL)
4. Otherwise check if the ref number is +1 from the previous row

IF isnull([Row-1:Ref number])
then '-'
elseif [Ref number] = [Row-1:Ref number]+1 
then 'Yes' 
else 'No' 
endif
