Hi,
In the Repair order RAS, click on the procurement Tab page and check what is the Requirement type
In standard it will be SERP ( it determines based on the Item category and MRP type )
Now with Requirement type SERP check what is the requirement class assigned in OVZH transaction
In standard it will be 204
Now take the requirement class 204 and in transaction code OVZG check what is the Order type
In standard it will be SM03, here you can make changes
you have to ensure that, if you use SM02 instead of SM03, Revenues will be posted directly to SM02 as per standard and you cannot carryout Settlement to Repair order and cost will not be finally posted to CO-PA
so make necessary settings in this regard, take help of your CO
