Hit the 'Help' hyperlink on your PS page, most companies have their People Books setup on this 'Help' link. Go through the People Books; I'm sure all your doubts will get clarified.
For instance, we would like to say that employee A work in Finance the first week of May, 2011. How can we change this without affecting records outside of this week? I'm far from a PS expect but would your suggestions not affect data beyond May 9th?
For instance, if this person worked in HR from June 1st - June 30th / 2011, in Receiving from July 1st to Aug 30/2011, would this data stay intact?
Unfortunately, i don't have access to People Soft books.
