• What is the cause and solution for SAP error message CNV_DMC_MC_EXCEPTION084 - The table field &1 does not exist ?

  The SAP error message CNV_DMC_MC_EXCEPTION084 indicates that a specific table field referenced in a data migration or conversion process does not exist in the target system. This error typically arises during data migration activities, especially when using tools like the SAP Data Migration Cockpit (DMC) or during system conversions.
  Cause:
  
  Field Name Mismatch: The field name specified in the migration mapping does not match any field in the target table. This could be due to a typo or an incorrect field name.
  Version Differences: The source and target systems may be on different versions of SAP, leading to discrepancies in table structures. Fields present in the source system may not exist in the target system.
  Custom Fields: If the source system has custom fields that are not present in the target system, this can lead to this error.
  Data Model Changes: Changes in the data model between different SAP versions or releases can result in certain fields being removed or renamed.
  
  Solution:
  
  Verify Field Existence: Check the target system's data dictionary (transaction SE11) to confirm whether the field exists in the specified table.
  Correct Mapping: If the field does not exist, you may need to adjust the mapping in your migration project to either remove the field or map it to an existing field in the target system.
  Update Data Model: If the field is essential for your migration, consider updating the target system's data model to include the necessary fields, if feasible.
  Consult Documentation: Review the migration documentation for any notes on changes in the data model between the source and target systems.
  Use Alternative Fields: If the field is no longer available, look for alternative fields that can serve the same purpose in the target system.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), and ST22 (Dump Analysis) to investigate further.
  SAP Notes: Check for relevant SAP Notes that might address known issues or provide guidance on data migration.
  Migration Tools: Familiarize yourself with the SAP Data Migration Cockpit and its capabilities, as well as any specific configurations that may be required for your migration scenario.
  Testing: Always perform thorough testing in a development or quality assurance environment before executing migrations in production.
  
  By following these steps, you should be able to identify the cause of the error and implement a suitable solution.
