What would happen if the dimensions for a particular SKU is not present at Amazon Portal?


Assure pulls the dimensions from  amazon portal and sends to the amazon back-end. If dimensions are not present at portal, inventory will be updated without dimensions at Amazon Back-end against which Amazon can take the order from customer, but not able to push the same to Assure.


Error '401 Access denied' while using Amazon MWS scratch pad?
