Due to caching within Azure when editing models which may take 10-15 minutes or longer, see Azure Digital Twins - Manage DTDL models, the recommended approach for when a UDT at the Edge requires modification is to use versioning of in the UDT name.

Replicate the UDT adding a version number to the name ie. UDT_name_1.0.0. In your UDT Definitions you will now have both the original UDT and the modified one.  For each of your tags using this original UDT, edit these to use the Parent Type of your modified UDT and refresh Transmission.

A new Azure Digital Twin model will be created along with the associated Digital Twin(s) for that model. 

SELECT * FROM digitaltwins DT WHERE IS_OF_MODEL(DT, 'dtmi:domain:Conveyor;1', exact)
