Carrier charge upload

hi Everyone,

Is there any way to mass upload new carrier charge in the system that would expire exiting one?

In our case, when transporter change their prices, it is not a linear (or linear %) increase so R4972 is of little help here.

What we get is a new set of tables by weight range and destination and rate type.

At the moment, we are manually expiring each previous set of charge and uploading new rates one by one.

I was wondering if there was any simpler process where I could update every rate in one upload?

Thanks

Nicolas
