Route-Copying-error

Hi,

I am facing a problem while changing the route of production order in the created state.

The scenario is i have a active and inactive routes(Both are parallel routes with primary and secondary operations) after creating production order i want to change the route . So i tried to change it from the route of production order by clicking functions button and copy but i am getting following error while selecting the route as"Base operation of operation for base item does not exist".

I request any one please help me in solving this problem.

What is the status of the production order?

Is the route associated with the item you are making?
