Hi,
If users don't need historic data then filling setup tables is not required.
As per the CMOD logic enhanced field will be filled in daily delta loads.
But once you done enhancement, you need to be very careful while moving transports to prod system.
Source system need to be locked and clear all delta queues(SMQ1/RSA7/SM13/LBWQ).
Clearing delta queue means we need to load all delta records to bw.
Thanks
