Hi
Error - Each GROUP BY expression must contain at least one column that is not an outer reference.
SELECT T1.U_VendCode,T1.U_CabNo,T1.U_VendName as "Vendor Name",Count(*), (Select Count(*) from [tbl2] where T1.U_APDE <> 'N' group by T1.U_VendCode,T1.U_CabNo,T1.U_VendName,T1.U_Custcode,T1.U_Custname,T1.U_APDE,T1.U_ARDE,T1.U_ItemCode), T1.U_CustCode as "Cust Code",T1.U_CustName as "Cust Name",T1.U_ItemCode FROM [tbl1] T0 inner join [tbl2] T1 on T0.Docentry = T1.DocEntry where (T1.U_ItemCode is not null) and (T0.U_DATE BETWEEN '2021-03-01' and '2021-03-31' ) and T1.U_CustCode = 'A01' group by T1.U_VendCode,T1.U_CabNo,T1.U_VendName,T1.U_Custcode,T1.U_Custname,T1.U_APDE,T1.U_ARDE,T1.U_ItemCode
