PR numbers in erWIN

Hello, I hope someone can help me here… I’m, like so many people looking for the PR numbers for my brakes… I don’t get the list displayed in erWin, or I don’t find it… All I found are the basic data and reference instructions… there are again only all possible PR numbers listed… Can someone tell me exactly where to get the build list exactly before I fuck up the next “flatrate”…? Thank you! Greeting ebys
