Warranty check in service order(iw31)

Hi all,

I have created material with warranty period 1 year. Our scenario is when the customer return the material due to a problem, We need to create service order with reference to service notification. Here i am adding the service components in service order. If the material is with in the warranty period.

Here my problem is

1) how the system will check the warranty periods(if material comes under the warranty or beyond the warranty)

Business scenario is

Service notification-- > Service order -- -> M I G O

---

>Service completion(iw42) (If material is under warranty there is no need of billing) ( if not it continues to billing -

---

>Billing request---> Billing)

In this business scenario, where i have to get the warranty indication whether the material having warranty or not.

Thanks in advance,

C Chaitanya
