Permit Class is red. This is the reason of no automatic assignment.
- If a permit class could not be determined, the traffic light is RED.
A permit class cannot be determined in the following three cases:
- You have not defined a permit group in Customizing.
- You have defined a permit group in Customizing, but still no permit class is assigned to it.
- The permit class assigned in Customizing is not available (any longer).
Check below config
Plant Maintenance and Customer Service->Master Data in Plant Maintenance and Customer Service->Basic Settings->Permits->Define Permit Groups
Permit class should match with class created by you.
