Issue during Process Order creation: system cannot find valid routing
I am getting the below error(msg: CO 831) when I am trying to create a Process Order
"No default value maintained for op. generation for order type PI01"
Daignosis: You are creating an order for which the system can find no valid routing. When generating an operation the system cannot find any default value for the order type PI01 in plant XXXX
Sys Response: The system reacts with a termination since you cannot create an order without an operation and the data required to generate an operation has unfortunately not been maintained
I am not sure what (config) am I missing?
Please let me know if you can guide me to resolve it.
