• What is the cause and solution for SAP error message SOI802 - Table &1 field &2 is changed to a key field ?

  The SAP error message SOI802 indicates that a field in a table has been changed to a key field, which can lead to issues if the field was previously not defined as a key field. This error typically arises during data operations such as data migration, table modifications, or when working with data models in SAP.
  Cause:
  
  Field Definition Change: The field in question was modified in the Data Dictionary (DDIC) to become a key field. This change can affect how data is accessed and indexed.
  Data Consistency Issues: If the field was previously not a key field, existing data may not conform to the new constraints imposed by making it a key field.
  Data Model Changes: Changes in the underlying data model or structure can lead to this error, especially if the application logic relies on the previous definition.
  
  Solution:
  
  Check Table Definition: Review the table definition in the Data Dictionary (transaction SE11) to confirm the changes made to the field. Ensure that the field is correctly defined as a key field.
  Data Migration: If the field is now a key field, ensure that all existing records in the table have unique values for this field. You may need to clean up or modify the data to meet the new constraints.
  Adjust Application Logic: If the application logic relies on the field not being a key field, you may need to adjust the logic to accommodate the new definition.
  Transport Requests: If the change was made in a development environment, ensure that the transport requests are correctly moved to the production environment, and that all related changes are included.
  Consult Documentation: Review any relevant SAP notes or documentation that may provide additional context or specific steps to resolve the issue.
  
  Related Information:
  
  Transaction Codes: Use SE11 (Data Dictionary) to check the table structure and field definitions.
  SAP Notes: Search for relevant SAP Notes that may address this specific error or provide guidance on handling changes to key fields.
  Data Consistency Checks: Use transaction codes like SE14 (Database Utility) to check and repair inconsistencies in the database.
  Testing: After making changes, thoroughly test the application to ensure that it behaves as expected with the new key field definition.
  
  If the issue persists after following these steps, consider reaching out to SAP support or consulting with a technical expert familiar with your specific SAP environment.
