UnitConvert table


Whats the difference between qty() and convertqty() in the UnitConvert table? When I put an entry in the trade agreements and wanted to convert the quantity unit from ‘Each’ to ‘Case of 002’ or something 2 is the factor and it needs to display in the form.Same way for ‘Case of 003’ 3 needs to be displayed and so on.But this is not happening and it shows up 1 everytime.I have used convertqty method.
