We often process and pack orders over a weekend and use the ShippedTime to mark orders as shipped in the future. So for instance, we book, print and pack orders on a Sunday but make the label postage date as Monday and also mark them as shipped as Monday through the CompleteSale API.
Problem is, if its an Easter Weekend and we wanted to process orders on a Good Friday we would be unable to mark them as shipped Tuesday (Next Posting Day) because the ShippedTime API call is limited to a Maximum of 3 Days in the future.
So can you please consider extending the ShippedTime value to above 3 days? The minimum would have to be 5 days!
Cheers Guys ;-)
