How To Fix CNV_IUUC_REPL_TS009 - Number of DTL_MT_DATA_LOAD jobs is not equal to the no. of logical locks

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_IUUC_REPL_TS - Messages for troubleshooting functions

• Message number: 009

• Message text: Number of DTL_MT_DATA_LOAD jobs is not equal to the no. of logical locks

What causes this issue?

There is a difference between the number of logical lock entries and the
number of replication processes that are currently running.

System Response

This is a potential error situation. If a replication process cancels
without removing the corresponding logical locks, further replication
processes may be unable to run properly.

How to fix this error?

Check the logical locks for object DMC_JOB by using the
<DS:TRAN.SM12>Lock Overview</>. They must correspond 1:1 to the current
replication jobs that are running (you can check the jobs that are
running by using the <DS:TRAN.SM37>Job Overview</> transaction.
If there are more locks than jobs, or vice versa, stop all the
replication jobs and then delete any lock manually that might still
exist before restarting the replication jobs.

Procedure for System Administrators

Logical locks for object DMC_JOB obtained from function module
ENQUE_READ2.

• What is the cause and solution for SAP error message CNV_IUUC_REPL_TS009 - Number of DTL_MT_DATA_LOAD jobs is not equal to the no. of logical locks ?

  The SAP error message CNV_IUUC_REPL_TS009 indicates a mismatch between the number of DTL_MT_DATA_LOAD jobs and the number of logical locks in the context of data replication or migration processes, particularly in the SAP Landscape Transformation (SLT) or SAP Data Services environments. This error typically arises during the data loading phase when the system expects a certain number of jobs to be running or completed, but the actual number of logical locks does not match this expectation.
  Cause:
  
  Job Configuration Issues: There may be a misconfiguration in the job settings, leading to an incorrect number of jobs being initiated.
  Locks Not Released: Logical locks may not have been released properly, causing the system to think that there are still active jobs.
  Job Failures: Some of the DTL_MT_DATA_LOAD jobs may have failed or been terminated unexpectedly, leading to a discrepancy in the expected versus actual job count.
  Concurrency Issues: If multiple processes are trying to access the same data or resources, it can lead to contention and locking issues.
  System Performance: High system load or performance issues can cause delays in job execution and lock management.
  
  Solution:
  
  Check Job Status: Review the status of the DTL_MT_DATA_LOAD jobs in the job monitoring tool (e.g., SM37) to identify any failed or stuck jobs.
  Release Locks: If there are logical locks that are not being released, you may need to manually release them or restart the relevant processes.
  Adjust Job Configuration: Ensure that the job configuration settings are correct and that the number of jobs matches the expected workload.
  Monitor System Performance: Check for any performance bottlenecks in the system that may be affecting job execution and locking mechanisms.
  Restart the Process: If the issue persists, consider restarting the data loading process to reset the job and lock states.
  Consult Logs: Review the application logs for any additional error messages or warnings that could provide more context on the issue.
