Need To Capture Item Warranty - Of suppler & Customer

Hi

We are using R12.1.3

In inventory module  items are received against  the issued  PO to supplier.

Items are received by our the inventory dept.

Now the acquirement is below

For all item we receive - our supplier  will provide  warranty period  say 6 months ( it varies  -6 month s/12 months/etc)

we receive  items  -based on item code and serial numbers

This item will be issued to our  customer.

While issuing to customer we will give  our own warranty period to customer ( it is vary from supplier  provided warantty)

How to capture  these information in inventory -is there any standard option field.  Or should we use  the DFF
