I could not hold myself from entering this post, to share what I learned of doing a relatively complex process with some simple steps.
Reformatting Accounts in a Company with Transactions entered against it, is not easy and I thought it's almost impossible if the Segment length is required to get reduced from the original length. Do read this GP Community post and I bet you would learn something.
I am quite surprised and amazed to know how much I still need to learn in GP. What I know is less compared to what actually is.
Thought this would be useful for someone somewhere with same set of requirement.
