How to restrict Manuel creation of PM work order.

Dear all,

I have requirement to restrict Manuel creation of Preventive Maintenance work order [Eg : PM02].

Initially it was : User can create PM02 work orders manuelly. and also through maintenance plans with background creation of Notification M2.

Now user don't want to create PM02 work orders manuelly. Need to restrict it. Only through maintenance plans order should get created with Notification.

I have solution by creating user status with users status set forbidden to create order , so system throw error "User status active ...." if we try to create order directly.

By doing this 50% problem solved, however, while generating orders through auto scheduling [ IP30] system throw error "User status active...".

Is there any alternate solution to handle this type scenerio? Please suggest.

Regards

Anand
