Hi,
Before the transport, please clear all queues from SMQ1/RSA7. i.e mean load all delta to bw targets.
When you recreate COPA data source then you need to do reinit again.
Without reinit if you trigger delta at prod after the transport it will fail due structural changes.
So you need to do reinit again.
What about historic data for added two fields?
if you need historic data then you need delete the whole data from targets and again reload .
if you don't need historic data then after the transport just do the re init without data transfer and set delta pointer. now onwards delta will brings data for added fields also.
Thanks
