  The SAP error message /CFG/DSY_DS091 indicates that there has been a change in the foreign key relation mappings for a check table in the Data Dictionary. This typically occurs when there are modifications to the structure of a table or its relationships with other tables, which can affect data integrity and consistency.
  Cause:
  
  Change in Table Structure: The error may arise if the structure of the check table (the table being referenced) has been altered, such as adding or removing fields, or changing data types.
  Foreign Key Relationship Changes: If the foreign key relationships have been modified, such as changing the referenced table or field, this can trigger the error.
  Inconsistent Data: If there is existing data that does not comply with the new foreign key constraints, this can also lead to this error.
  
  Solution:
  
  Check Table Structure: Review the structure of the check table and ensure that it aligns with the foreign key definitions. You can do this using transaction SE11 (Data Dictionary).
  Adjust Foreign Key Relationships: If necessary, adjust the foreign key relationships to ensure they are correctly defined. This may involve redefining the foreign key in the relevant table.
  Data Consistency Check: Run consistency checks on the data to ensure that all existing records comply with the new foreign key constraints. You can use transaction SE14 (Database Utility) to check and adjust the database.
  Re-activate the Table: If changes have been made, you may need to re-activate the table or the foreign key relationship to ensure that the changes take effect.
  Transport Requests: If the changes were made in a development environment, ensure that the transport requests are correctly moved to the quality and production environments.
