One of the many features within Clever Trade Plus is Mandatory Ship-To codes, giving Users the ability to be even more specific about the delivery of goods.
The purpose of this new feature is to warn a User on releasing a "Sales Order" where a Ship-To code has not been specified. In the instance of your Customer being unable to accept deliveries (they may be a head office for example), you never want to run the risk that the goods could be shipped to this address.
Providing an error reminds the user to select an alternative address so you can be safe in the knowledge they will be shipped correctly.
For more information, please read through the following articles on how to set this up and use this feature.
