• Message class: CNV20400 - Message class CNV20400

• Message number: 016

• Message text: Table &1 has more than two parameters; no simulation

What causes this issue?

A merge of data records can be simulated only for tables that have two
or more parameters in table CNVFIPARS. However table &V1& has more than
two parameters.

• What is the cause and solution for SAP error message CNV20400016 - Table &1 has more than two parameters; no simulation ?

  The SAP error message CNV20400016 indicates that a specific table (denoted as &1 in the error message) has more than two parameters, which prevents the simulation of a conversion or migration process. This error typically arises during data migration or conversion activities, particularly when using SAP's Data Migration tools or the SAP S/4HANA Migration Cockpit.
  Cause:
  The error occurs because the system expects tables involved in the migration process to have a limited number of parameters (usually two) for simulation purposes. When a table has more than two parameters, the simulation cannot be performed, leading to this error message.
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Review the Table Structure: Check the structure of the table mentioned in the error message. Identify the parameters and their configurations.
  
  
  Limit Parameters: If possible, modify the table or the migration logic to limit the number of parameters to two. This may involve adjusting the data model or the way data is being processed.
  
  
  Check Migration Settings: Ensure that the migration settings are correctly configured. Sometimes, adjusting the settings can help in bypassing the limitation.
  
  
  Consult Documentation: Refer to SAP documentation related to the specific migration tool you are using. There may be guidelines or best practices for handling tables with multiple parameters.
  
  
  Use Alternative Approaches: If the simulation is not critical, you may choose to proceed with the actual migration without simulation. However, this should be done with caution, as it may lead to unexpected results.
  
  
  Contact SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP Support for assistance. They may provide insights specific to your system configuration and the migration process you are using.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context.
  Migration Cockpit: Familiarize yourself with the SAP S/4HANA Migration Cockpit and its limitations regarding table parameters.
  Data Migration Best Practices: Review best practices for data migration in SAP to ensure a smooth process and avoid common pitfalls.
  
  By following these steps, you should be able to address the CNV20400016 error and proceed with your data migration or conversion activities.
