Please find attached your load with abit more work done to it...
By loading your data this way you can use the power of Qlik much more easily in the front end.
Ive added a pivot table to show you your data back as you presented it but now you can start cutting and anayzing your data alot easier. I've also created a measure for your total amount (Amt + tax). you should load up values that can be derived from others unless that will put alot of load onto the front end use of the dashboard.
This should get you started. Please mark any replies as either helpful/Correct.
