Note Number 105621:Authorisation for pricing conditions

Hi,

I am working with note number 105621.

This is a modification note which is used to create authorisation for the pricing conditions.

SAP has given the steps on how to proceed .But in step number 5 they are talking about 5 user exits.I cant understand what i should with that user exits.If any one has implemented this note please tell me how to proceed..

Where can i see these user exits and how exactly should i proceed with the user exits.

Thanks&Regards
