Hi Roy,
Everything is possible in B1.
Try this and look to the headers of the columns.
Not tested.
SELECT T2.SlpName, Count(*) as 'Order converted from quotes in period', (select COUNT(*) from OQUT t1 where (T1.DocDate BETWEEN [%0] AND [%1]) and T1.SlpCode = T0.SlpCode) as 'Total Quotations in period' , Count(*) *100 /
(select COUNT(*) from OQUT t1 where T1.DocENtry = (Select Distinct T2.DocEntry from QUT1 t2 inner join rdr1 t3 on T3.BaseEntry = T2.DocEntry and T3.BaseLine = T2.LineNum inner join ORDR T4 on t4.DocEntry = T3.DocEntry where T2.DocEntry = T1.DocEntry and T4.DocDate BETWEEN [%0] AND [%1]) and T1.SlpCode = T0.SlpCode) as 'percentage'
FROM OQUT T0 inner join OSLP T2 on T2.SlpCode = T0.SlpCode where T0.DocENtry = (Select Distinct T2.DocEntry from QUT1 t2 inner join rdr1 t3 on T3.BaseEntry = T2.DocEntry and T3.BaseLine = T2.LineNum inner join ORDR T4 on t4.DocEntry = T3.DocEntry where T2.DocEntry = T0.DocEntry and (T4.DocDate BETWEEN [%0] AND [%1]))
Group by T0.SlpCode, T2.SlpName
I hope it helps
