Service/maintenance order type SM01 not completely maintained in plant 1001

Dear All,

Am trying to configure Service Management where there is a scenario in which , when the user creates a Sales order for a installation item say TV or Fridge, automatically Service order has to be generated.

I have checked all the item Category Settings but am getting an error

Service/maintenance order type SM01 not completely maintained in plant 1001

Message no. IW216

Diagnosis

For the selected order type and plant, no check control is maintained in Plant Maintenance/Service in 'Availability Check for Materials, PRTs and Capacities'.

Procedure

A check control must be maintained for this combination of order type and plant.

Can anyone throw some light on this as i know you would have faced this problem.
