How To Fix CNV_MBT_ME002 - Simulation of table &1 did not generate log entries

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_MBT_ME - Messages for Mapping Engine and Merge Simulation

• Message number: 002

• Message text: Simulation of table &1 did not generate log entries

What causes this issue?

The conversion of table &V1& was simulated and no log was written. This
may be because the applied mappings did not cause entries of the table
to fall together. Another posibillity is that none of the merged entries
meet the conditions specified in the simulation.

System Response

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

• What is the cause and solution for SAP error message CNV_MBT_ME002 - Simulation of table &1 did not generate log entries ?

  The SAP error message CNV_MBT_ME002 indicates that during the simulation of a table, no log entries were generated. This message is typically associated with the SAP Migration Cockpit or data migration processes, particularly when using the Migration Object Model (MOM) for data transfer.
  Cause:
  
  
  No Data to Process: The most common reason for this error is that there are no records in the specified table that meet the criteria for the simulation. If the table is empty or if the selection criteria filter out all records, no log entries will be generated.
  
  
  Incorrect Configuration: There may be an issue with the configuration of the migration object or the mapping of fields, which could lead to no data being processed.
  
  
  Simulation Mode: The simulation mode might not be set up correctly, or the parameters for the simulation might not be defined properly.
  
  
  Authorization Issues: Lack of proper authorizations to read the data from the source table can also lead to this error.
  
  
  Solution:
  
  
  Check Data Availability: Verify that there is data in the source table that meets the selection criteria. You can do this by executing a simple SELECT query on the table.
  
  
  Review Configuration: Ensure that the migration object is correctly configured and that the mapping of fields is accurate. Check if the selection criteria are too restrictive.
  
  
  Adjust Simulation Parameters: Review the parameters set for the simulation. Make sure that they are correctly defined to include the data you expect to process.
  
  
  Check Authorizations: Ensure that the user executing the simulation has the necessary authorizations to access the data in the source table.
  
  
  Run in Actual Mode: If you are only testing, consider running the migration in actual mode (if applicable) to see if it generates log entries.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration object you are working with to ensure that all steps are being followed correctly.
  
  
  Related Information:
  
  Transaction Codes: You may want to check relevant transaction codes such as LTMC (for Migration Cockpit) or SIMG (for customizing).
  SAP Notes: Look for SAP Notes related to the specific migration object or error message for any known issues or patches.
  Logs and Traces: Check the application logs (transaction SLG1) for any additional error messages or warnings that might provide more context.
  Community Forums: Consider searching or posting on SAP Community forums for insights from other users who may have encountered the same issue.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution.
