• What is the cause and solution for SAP error message CNV_CMIS_M323 - Tables (&1->&2) have different structure; Other conflicts may be created ?

  The SAP error message CNV_CMIS_M323 indicates that there is a structural mismatch between two tables during a data migration or conversion process. This typically occurs in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other conversion tools.
  Cause:
  The error arises when the two tables involved in the migration or conversion process have different structures. This could be due to:
  
  Different Field Definitions: The fields in the source table and the target table may have different data types, lengths, or attributes.
  Missing Fields: One of the tables may have fields that the other does not, leading to a mismatch.
  Additional Fields: The target table may have extra fields that are not present in the source table.
  Changes in Table Structure: If the database schema has been altered (e.g., during an upgrade or modification), it can lead to discrepancies.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Analyze the Table Structures:
  
  Use transaction codes like SE11 (Data Dictionary) to compare the structures of the two tables involved in the error.
  Identify the differences in field definitions, data types, lengths, and attributes.
  
  
  
  Adjust the Source or Target Table:
  
  If possible, modify the source table to match the structure of the target table.
  Alternatively, adjust the target table to accommodate the structure of the source table.
  
  
  
  Mapping Configuration:
  
  If you are using a migration tool, check the mapping configuration to ensure that it correctly reflects the relationships and structures of the source and target tables.
  
  
  
  Consult Documentation:
  
  Review the documentation for the specific migration or conversion tool you are using to understand any prerequisites or requirements regarding table structures.
  
  
  
  Testing:
  
  After making adjustments, perform a test migration to ensure that the error is resolved and that data is being transferred correctly.
