DBM Warranty Functionality and Validation

Hi all

     When we enter a Labour value or Parts in Service Order. How can we identify whether the labour value or parts is under warranty.

     Also, we have a scenario where Vehicle warranty is 2 years. But aggregates of vehicle like Battery, ECU, brake etc might vary in warranty period.

     How can i map the aggregate warranty and validate it in Service order when i key in respective aggregates .

Regards
