My approach would be
- first to know the Business Process (getting KT from either a senior resource or Business). This is the first step wherever you go.
- second - if you understand the business process to some extent, if not fully, this will help you a lot while studying the existing configuration / customization working for that US company code
- third - since you said the roll over is for other country and would be using the template of US company code, get clarifications from Business on legal issues like tax structure which would be different from country to country.
- if that is the case, then you cannot use the existing pricing procedure. You need to go for new pricing procedure to meet the statutory regulations of the country where the roll over is going to take place. Having said this, obviously, the output of statutory documents would vary if not other internal documents. This means, you have to go with new enhancement
- next would be to list out interfaces and jobs that are running for US company code and check whether these interfaces are really required for the new company code. It is not that just because some interface are there in US company code for 15 years, you need to take. Of course, you should have some justification for this.
These are few tips you can take which comes to my mind as of now.
