SELECT @nr := (@nr+1) AS nr,p.* 
group by sal_snum,sal_trn,sal_trm ,sal_dt ,sal_tm,sal_emp 
FROM (
    select sal_snum as "Store Code",sal_trn as "Transaction Number", 
    sal_trm as "Register",sal_dt as "TrasactionDate",sal_tm as "TranactionTime", 
    sum(sal_tax) as "TotalTaxAmount","" as "CustomerCode", 
    "" As "CustomerCardType","" as "CustomerCardNumber", 
    "" as "TotalPointsOnTransaction","" as "Note1","" as "Note2", 
    sal_emp as "Staff 1 Code", "" as "Staff 2 Code","" as "Global Tax Code",
