Is there a Windchill REST Service endpoint that can return the Base Part Number of a Serial Number?

Hi Maria,

 Welcome to the PTC Community!

Thank you for your question. 

I’d like to recommend to bring more details and context to your initial inquiry. Also provide the product release and datecode. 

It also helps to have screenshot(s) to better understand what you are trying to do in your process. 

This will increase your chances to receive meaningful help from other Community members.
