• What is the cause and solution for SAP error message CNV_PE895 - Simulation parameter value &1 is not allowed ?

  The SAP error message CNV_PE895 indicates that a simulation parameter value provided in a conversion or migration process is not allowed. This error typically arises during data migration or conversion activities, particularly when using SAP's tools for data transformation or migration, such as the SAP S/4HANA Migration Cockpit or other data conversion tools.
  Cause:
  
  Invalid Parameter Value: The value provided for a simulation parameter does not meet the expected criteria or is outside the allowed range.
  Configuration Issues: There may be a misconfiguration in the migration settings or parameters that are being used.
  Data Type Mismatch: The parameter value may not match the expected data type (e.g., providing a string where a numeric value is expected).
  Business Logic Constraints: The value may violate business rules or constraints defined in the system.
  
  Solution:
  
  Check Parameter Value: Review the value you are providing for the simulation parameter. Ensure it is within the allowed range and meets the expected format.
  Refer to Documentation: Consult the SAP documentation or help files related to the specific migration or conversion tool you are using. This can provide insights into valid parameter values.
  Adjust Configuration: If the parameter is part of a configuration setting, ensure that all related settings are correctly configured.
  Test with Default Values: If possible, try running the simulation with default or known valid parameter values to isolate the issue.
  Consult SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on the parameters being used.
  Seek Help from SAP Support: If the issue persists, consider reaching out to SAP Support for assistance, providing them with details of the error and the context in which it occurred.
  
  Related Information:
  
  Transaction Codes: Depending on the context, you may be using specific transaction codes related to data migration (e.g., LTMC for Migration Cockpit).
  Migration Tools: Familiarize yourself with the specific migration tools and their parameters, as each tool may have different requirements.
  Testing Environment: Always perform tests in a non-production environment to avoid impacting live data.
  Logs and Traces: Check logs or traces generated during the migration process for additional details that may help diagnose the issue.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
