Can someone advise how to add an activity note to the below ar statement so that each invoice has a note on it.

Declare @d datetime set @d /*Select 1 from jdt1 t where t.duedate*/=[%1] select * from ( SELECT T1.CardCode, T1.CardName, T0.RefDate, T0.Ref1 'Document Number',     CASE  WHEN T0.TransType=13 THEN 'Invoice'           WHEN T0.TransType=14 THEN 'Credit Note'           WHEN T0.TransType=30 THEN 'Journal'           WHEN T0.TransType=24 THEN 'Receipt'           END AS 'Document Type',     T0.DueDate, (T0.Debit- T0.Credit) 'Balance'     ,ISNULL((SELECT T0.Debit-T0.Credit WHERE DateDiff(day, T0.DueDate,@d)=0 and DateDiff(day, T0.DueDate,@d)30 and DateDiff(day, T0.DueDate,@d)60 and DateDiff(day, T0.DueDate,@d)90 and DateDiff(day, T0.DueDate,@d)=121),0) '121+ Days' FROM JDT1 T0 INNER JOIN OCRD T1 ON T0.ShortName = T1.CardCode WHERE  T1.CardType = 'C' ) sub
