  The SAP error message CNV20551452, which states "Field of domain &1 not found in key of table &2," typically occurs during data migration or conversion processes, particularly when using SAP's Data Migration tools or during the execution of a conversion program. This error indicates that a field associated with a specific domain is not present in the key fields of the specified database table.
  Cause:
  
  Field Not in Key: The field defined by the domain is not part of the primary key of the specified table. In SAP, certain operations require that fields be part of the key to ensure data integrity and proper referencing.
  Data Model Changes: If there have been changes to the data model (e.g., fields added or removed) in the target system, this can lead to discrepancies.
  Incorrect Mapping: During data migration, if the mapping of fields from the source to the target is incorrect, it can lead to this error.

  Check Table Structure: Verify the structure of the table specified in the error message. Ensure that the field associated with the domain is indeed part of the key fields.
  Review Data Mapping: If you are performing a data migration, review the mapping of fields between the source and target systems. Ensure that all necessary fields are correctly mapped and that the key fields are included.
  Adjust Domain or Table: If the field should be part of the key but is not, consider adjusting the table structure to include the field in the key. This may involve modifying the database schema, which should be done with caution and proper testing.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion process you are using. There may be specific guidelines or prerequisites that need to be followed.
