Over the weekend we have tested AX in PROD. As far as we can test everything is working except canceling a delivery note will not work in Monday but likely Tuesday. Its very complex to do in R3, which is why MS did not do it we guess. There is a way to do it manually on Monday but Steffen or I will have to do it for you. Please let us know the sales order number and delivery note number you wish to be cancelled and we will do it for you.
