Acctivate allows users to assign a default product for shipping charges. This is the product used on the Release Invoice window for Sales Orders. In order to assign this ID as the default, you will first need to create a Product ID for shipping charges. The Item Type on the product needs to be Shipping to be able to use it as the default. Below is an example of which fields to select when setting up the product:
After creating the product, users can then assign it as the default product for shipping charges. This can be done by going to File > Configuration Management > Sales Orders > Order Options.

Without this assigned in Configuration Management, you may see a message like the one below:
