Validity periods / Pricing list

How can SAP show me the last record of the last validity period of a product?

For example i have a product with this validity periods:

01.01.2011 - 01.02.2011

02.02.2011 - 01.03.2011

02.03.2011 - 01.04.2011

I just want SAP to display the last validity period (02.03.2011 - 01.04.2011), and i can just put on "Validity range" 01.03.2011 - xxxx because i have more products that have different periods.. i want to make a list of all products with the last validity period they have :/

Please help 😔 !!

Thank you in advance.
