  The SAP error message CNV_CMIS_A_20203 indicates that there is a mismatch in the number of key fields between two systems during a data migration or conversion process. This error typically arises in the context of using the SAP Conversion Management Information System (CMIS) or during data transfer between different SAP systems.
  Cause:
  The error occurs when the source system (system &2) and the target system (system &3) have tables (table &1) that have the same number of key fields, but the actual key fields themselves do not match in terms of their definitions, types, or configurations. This can happen due to:
  
  Schema Differences: The table structures in the two systems may have been modified differently, leading to discrepancies in key field definitions.
  Data Model Changes: Changes in the data model between different versions of SAP or customizations that have been applied to one system but not the other.
  Configuration Issues: Incorrect configuration settings in either the source or target system that affect how key fields are defined or recognized.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Compare Table Structures: Use transaction codes like SE11 (Data Dictionary) to compare the structures of the table in both systems. Check the definitions of the key fields, including their data types, lengths, and attributes.
  
  
  Adjust Key Fields: If you find discrepancies, you may need to adjust the key fields in either the source or target system to ensure they match. This could involve adding, removing, or modifying key fields.
  
  
  Check Customizations: Review any customizations or enhancements that may have been applied to either system. Ensure that any custom fields or changes are consistently applied across both systems.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific tables and their key fields to understand any known issues or required configurations.
  
  
  Testing: After making adjustments, perform a test migration or data transfer to verify that the error has been resolved.
