This feature was added with Update 25.
You can remove the ENS system from the incoming transmittal form that will allow you to use the transmittal number of the vendor or the supplier. This further helps to easily find the original transmittal in SDx.
To delete the relation between the incoming transmittal class definition and the ENS definition, a template document, Transmittal Incoming ENS Remove Template, is delivered and accessible through the Desktop Client. For information on how to access the template document and load the file into the system, see Enable new features and functionality using template files.
