> Good morning
> After creating an ORDER, it is generated in the Created state, then I enter the order, I change the state (for example to the "Approved" state) and I CLICK in the button Approve Order, but the action does not execute and the following error is generated.
> Error Calling event: org.ofbiz.webapp.event.EventHandler.Exception: Service invocation error (Could not commit transaction for service [ChangeOrderStatus] call: Roll back error, could not commit transaction, was rolled back instead because of: Error in simple-method [Convert UOM values [file:/C:/apache-ofbiz-13.07.03/frameork/common/scrpt/org/ofbiz/common/CommonServices.xml#convertUom]]:; [UOM Conversion Relationship Not Found]).
