• What is the cause and solution for SAP error message /CFG/DSY_DS079 - Foreign key relation for check table &1 removed from field &2 ?

  The SAP error message /CFG/DSY_DS079 indicates that there is an issue with a foreign key relationship in the data dictionary. Specifically, it means that a foreign key relation for a check table has been removed from a specified field. This can occur during data model changes, such as when a field is modified or when the underlying table structure is altered.
  Cause:
  
  Field Modification: The field in question may have been modified in a way that invalidates the foreign key relationship.
  Table Structure Changes: Changes to the check table or the primary table can lead to the removal of foreign key constraints.
  Data Dictionary Changes: If the data dictionary is altered (e.g., through transport requests), it can lead to inconsistencies in foreign key relationships.
  Inconsistent Data: If there are existing records that do not comply with the foreign key constraints, the system may remove the relationship to maintain data integrity.
  
  Solution:
  
  Check Table Structure: Review the structure of the check table and the field in question to ensure that they are correctly defined.
  Recreate Foreign Key: If the foreign key relationship is necessary, you may need to recreate it. This can be done using transaction SE11 (Data Dictionary) to redefine the foreign key relationship.
  Data Consistency Check: Ensure that all existing data complies with the foreign key constraints. You may need to clean up or adjust data in the relevant tables.
  Transport Requests: If the issue arose after a transport, check the transport logs for any errors or warnings related to the data dictionary changes.
  Consult Documentation: Review SAP documentation or notes related to the specific version you are using, as there may be known issues or patches available.
  
  Related Information:
  
  Transaction Codes: Use SE11 to view and modify data dictionary objects, and SE14 for database utility operations.
  SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that may address this specific error or provide guidance on foreign key relationships.
  Debugging: If the issue persists, consider debugging the application or process that triggered the error to identify the root cause.
  
  If you are unable to resolve the issue, it may be beneficial to consult with your SAP Basis or ABAP team, as they can provide deeper insights into the data model and assist with more complex troubleshooting.
