How to fix this error?

In transaction LTRC, you can view the possible causes of the issue. On
the tabs <ZK>Table Overview</> and <ZK>Data Transfer Monitor</>, you can
choose the <ZK>View Errors</> pushbutton. On the tab <ZK>Application
Logs</>, you can also view the logs for the initial load and for the
replication process.
If you do not find any issues, we recommend monitoring the replication
process over a period of time. You can do this by using the expert
function <ZK>Display Replication Statistics</> (in transaction LTRC on
the tab <ZK>Expert Functions</>).
In addition, you can use the expert function <ZK>View Unprocessed
Logging Table Records</> to monitor the number of entries in the logging
table.
If there are consistently high latency values, there may be issues with
the connections to the source or target systems, or issues within the
operations executed in these systems.
If you see different latency values (maybe aligned your business hours),
it is likely that the amount of changes in the source system is higher
than what SAP Landscape Transformation Replication Server can transfer
with one job. If this is the case, options for improving latency include
filtering the data, or specifying ranges for the logging table (for more
information, see <ZK>Performance Options</> in transaction LTRS).
