Dear,
in a simple way to track equipments or F/Ls we need to have when we need to assign the seq.no for equipment views in SPRO settings.
Then while creating master, we need to assign the data AS
Now while creating an order against this equipment/F/L system populates a message as
Some times business may require not have any maintenance orders internally while the technical object falls under warranty for typical equipment categories.For such cases you can have restriction using exits at the time of creation of orders only for such equipments falls under warranty dates.
Hope this may help you to understand little bit about warranty in PM
Regards,
Pardhu
