I have faced this error while creating a prod order which is pasted below.
bold No scheduling levels have been defined for production orders in
Customizing for plant X, order type XY01 and production scheduler * .
You cannot conduct any scheduling until a selection ID for detailed
planning, rough-cut planning or production rate planning has been
entered. The selection ID determines the priority for the selection of
the routing according to the criteria task list usage, type and status.
Moreover the scheduling type must be maintained.
Maintain the scheduling parameters by entering a selection ID for
detailled planning, rough-cut planning or production rate planning and
select the scheduling type.
When i tried to click execute function system gave a message object not found or maintained.
Please advise me gurus,
