My company is in the early stages of making a move from ECC 6.0 to S/4HANA. I thought it would be interesting to give you my initial impressions about what I have found out about Controlling in the new system. Since we started out with ECC 6.0, we don’t have the baggage of things like “classic G/L” versus “new G/L”, and frankly, I couldn’t explain the differences there. We first got access to an S/4HANA sandbox for a “test drive” of the system. This is a very important step in the transition and has helped me get a much better understanding of how the new system works than through looking at documentation and watching training videos. What follows are my initial impressions based on my experiences in the sandbox. Hopefully, this will be useful for those of you who are either making the move or are contemplating making the move.
