Specifically, the error states that the two tables referenced (denoted as &1 and &2) do not have a shared reference field, which is necessary for the operation to proceed.
  Cause:
  
  Missing Foreign Key Relationship: The two tables do not have a defined foreign key relationship, which means there is no common field that can be used to link the records from both tables.
  Incorrect Table Configuration: The tables may not be configured correctly in the data model, leading to the absence of a shared reference field.
  Data Model Changes: Changes in the data model or database schema may have removed or altered the relationship between the tables.

  Solution:
  
  Check Table Definitions: Review the definitions of both tables to ensure that they have a common field that can be used as a reference. This may involve checking the data dictionary (SE11) for the tables.
  Define Foreign Key Relationships: If a foreign key relationship is missing, you may need to define it in the data model. This can be done using transaction SE11 or SE12.
  Modify Queries/Reports: If you are working with a query or report, ensure that you are using the correct fields to join the tables. Modify the query to use a valid reference field.
  Consult Documentation: Review the documentation for the specific tables to understand their intended relationships and how they should be used together.
  Data Migration or ETL Processes: If this error occurs during data migration or ETL processes, ensure that the mapping between the source and target tables is correctly defined.
