We are experiencing quite a growing group of customers who has implemented external sales processes using constraint based configurators. The reason for using an external configurator are mainly based on requirements related to Web based sales processes. I would like to suggest to have a data entity or API developed for D365FO, which will enable a Configuration import function together with a sales order import function. This means creating a configuration from imported external set Attribute values per sales line. The values should be imported and validated in the constraint motor exactly as they were typed in, but of cause throwing execution errors in a log. If the validation is succesfull the system goes on by creating BOM, routing an pricing calculation in exactly the same ways as if they we typed in.
