How To Fix CNV_DMC_HC053 - &1 - &2: Maximum latency (&3) has exceeded warning threshold by &4

CNV_DMC_HC053 - Overview

• Message type: E = Error

• Message class: CNV_DMC_HC -

• Message number: 053

• Message text: &1 - &2: Maximum latency (&3) has exceeded warning threshold by &4

What causes this issue?

SAP Landscape Transformation Replication Server calculates the time
between the recording of a change in the source system and sending this
data to the target system. The respective threshold has been exceeded.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Many different elements influence latency. It is always a good idea with
starting to monitor the latency values over some time. You can view
historical latency information in transaction LTRC. On the tab
<ZK>Expert Functions</>, choose <ZK>Display Replication Statistics</>.
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).

CNV_DMC_HC053 - Details

• The SAP error message CNV_DMC_HC053 indicates that a maximum latency threshold has been exceeded during a data migration or conversion process. This message is typically associated with the Data Migration Cockpit (DMC) or the SAP S/4HANA migration process. Here’s a breakdown of the components of the error message:
  
  
  
  Cause: The error occurs when the latency (the delay in processing or transferring data) exceeds a predefined threshold. This can happen due to various reasons, such as:
  
  Network issues causing delays in data transfer.
  Performance bottlenecks in the source or target systems.
  High volume of data being processed at once.
  Resource constraints on the server (CPU, memory, I/O).
  
  
  
  
  Solution: To resolve this issue, you can take several steps:
  
  Monitor System Performance: Check the performance metrics of both the source and target systems. Look for CPU, memory, and I/O usage to identify any bottlenecks.
  Network Check: Ensure that the network connection between the source and target systems is stable and has
