Actual Gross Weight (GW) is the actual weight of the shipment
Volume Weight (VW) is calculated based on a cargo's size, measurement or dimensions
formula for calculating Using the English System: L x W x H in inches (in.) / 165 = vw (in lbs.) Using the Metric System: L x W x H in centimeters (cm.) / 6,000 = vw (in kgs.)
Chargeable Weight of cargo intended for air shipment is the actual gross weight (gw) or the volume weight (vw), whichever is greater.
Weight Break is the point at which the weight or chargeable weight of a shipment is large enough to be assessed the lower freight rates which are applicable to larger shipments, this is as per the carrier's tariff.
Volume Cut is discount offered for voluminous cargo. It is the same concept as weight break, but has its own formula to calculate.
If you have freight that is 100 Kilos and the chargeable weight is 200 Kilos, the co-loader or airline will offer 10.00 per Kilo with a 50/50 volume cut This means that you will subtract the actual weight from the chargeable weight and divide the sum by 2. Add this total to the actual weight and this is the amount you will be paying for. (200-100)/2 = 50 + 100 = 150 Kilo's Next you will need to break this down into an actual per kilo cost. You will do this by multiplying the 150 Kilos by the rate offered of 10.00. 150 X 10.00 = 1,500.00 Then dividing the sum of this by the chargeable Kilo's to get the actual per Kilo cost. 1,500.00 / 200 = 7.50 per Kilo *This volume cut can vary and may not always be 50/50, it could be 25/75, 40/60, etc...
Minimum (Min) is the lowest amount that can be charged for the service.
Maximum (Max) is the highest amount that can be charged for the service.

Summary
We are rewriting the rate db air - Phase one according to new simplified requirements, provided by Chikei Ho (Module Owner)
Current Business Process
Currently, Chikei has created an excel spreadsheet to maintain and search rates. Each office is sharing this spreadsheet using dropbox. http://www.dropbox.com/.
This enables each office to update their own portion of the rate sheet and allows them access to each offices rates.
Business Requirements
Core need
To upload excel spreadsheet into a database.
To be able to export the excel spreadsheet from the database.
Uploading the spreadsheet will replace any rates currently in the database.
