I am preparing myself for some job interviews, but am finding the periodic billing and milestone billing quiet difficult to understand with the help of the hands on excercises from SAP labs.the excercises were quiet do-able in the LABS where the R/3 was configured & customised beforehand but now when I try the same on a clean R/3 system ,I am facing a lot of obstacles.
I have a Sales order document type ZA02(replica of OR) and item category za02(replica of TAN).For contact type 'service and maintenance', I have "W V" available in the system[4.6c].With these parameters in hand I want to simulate a "periodic billing" and a "milestone billing" example. Could someone please mention a step-by-step method , starting from the scratch on how to go about with this. If someone can assist to explain this alongwith all the factors necessary in the 'Billing plan' customisation , then it will surely help to understand this complex situation.
Thanks for any help or assistance.
