Looking at the GGSCI STATS REPLICAT [replicat_name] command, that will return to you the information regarding the number of operations it has performed and on which tables. There are a couple of options that can be used to return the data differently.
Another option, that is much more reliable that just getting some object statistics is to use Veridata to compare the actual data between the source and target. This will not only ensure that row change made it to the target, but that the data is correct. It will also help protect against someone coming into the target directly and updating the data.
