• What is the cause and solution for SAP error message CNV_CMIS_M_10018 - Mapping values and parameters of participating systems are different ?

  The SAP error message CNV_CMIS_M_10018 indicates that there is a mismatch in the mapping values and parameters between participating systems during a data migration or conversion process. This error typically arises in the context of SAP's Conversion and Migration tools, particularly when using the SAP S/4HANA Migration Cockpit or similar tools.
  Cause:
  
  Inconsistent Data Mapping: The source and target systems may have different definitions for the same data fields. For example, if a field in the source system is defined as a string and in the target system as an integer, this can lead to mapping issues.
  Different Value Ranges: The value ranges for certain fields may differ between the systems. For instance, if one system allows a certain set of values for a field and the other system does not, this can cause a conflict.
  Missing or Incorrect Configuration: The mapping configuration may not be set up correctly, leading to discrepancies in how data is interpreted between the systems.
  Data Type Mismatches: If the data types of the fields being mapped do not match (e.g., date formats, numeric precision), this can trigger the error.
  
  Solution:
  
  Review Mapping Configuration: Check the mapping configuration in the migration tool to ensure that all fields are correctly mapped and that the data types are compatible.
  Align Value Ranges: Ensure that the value ranges for the fields in both systems are aligned. This may involve adjusting the source data or modifying the target system's configuration to accept the values from the source.
  Data Cleansing: Perform data cleansing on the source data to ensure that it conforms to the expected formats and value ranges of the target system.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using to understand the expected mappings and configurations.
  Testing: Conduct thorough testing with a subset of data to identify any further discrepancies before performing a full migration.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on best practices for data migration.
  Migration Cockpit: Familiarize yourself with the SAP S/4HANA Migration Cockpit and its functionalities, as it provides tools for mapping and transforming data during migration.
  Community Forums: Engage with SAP community forums or support channels where other users may have encountered similar issues and can provide insights or solutions.
  
  By addressing the underlying causes of the CNV_CMIS_M_10018 error, you can facilitate a smoother data migration process and ensure that the participating systems are aligned in terms of data mapping and parameters.
