As your mapping for the incoming to outgoing seems a movable entity based on the current period/year, I'd suggest you introduce some kind of metadata/config into a hash input/output and join it in as a lookup flow.

Please help with two things - 

1. is the sample data provided a complete list for your input or you would have more
2. what is the logic that has been taken into account during the data transformation
