Serialized item is shipped but a warranty contract is not created

Hello folks,

We have a issue where a serialized item is shipped but it neither created a warranty contract nor updated the IB record.

Here is our setup:

1. We have a serviceable item and a warranty item.

2. We have a BOM for the serviceable item  that has the warranty item in it.

3. The serviceable item(Qty:30) was ordered thru OM and the order was shipped.

4. Only one of the 30 serials has a warranty contract created and IB record updated accordingly.

Issue: We cant find the warrant contracts for the remaining 29 serials.

Any help is much appreciated.

Thanks,

--John.
