• What is the cause and solution for SAP error message E2189 - Foreign key &-& was deleted ?

  The SAP error message E2189, which states "Foreign key &-& was deleted," typically occurs when there is an attempt to access or reference a foreign key relationship that has been deleted or is no longer valid in the database. This can happen in various contexts, such as during data entry, report generation, or when executing certain transactions.
  Cause:
  
  Deleted Foreign Key: The foreign key relationship that the system is trying to reference has been deleted from the database.
  Data Integrity Issues: There may be inconsistencies in the data where the foreign key constraints are not being met.
  Configuration Changes: Changes in the configuration of the database or application that affect the foreign key relationships.
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), the foreign key might not exist in the target system.
  
  Solution:
  
  Check Foreign Key Configuration: Verify the foreign key relationships in the relevant tables. You can do this by checking the database schema or using transaction codes like SE11 (Data Dictionary) to view the table definitions.
  Data Consistency Check: Run consistency checks to ensure that the data adheres to the foreign key constraints. This can be done using transaction codes like SE14 (Database Utility) to check and repair inconsistencies.
  Restore Deleted Keys: If the foreign key was deleted unintentionally, you may need to restore it. This can involve recreating the foreign key relationship in the database.
  Review Transport Requests: If the issue arose after a transport, review the transport logs to ensure that all necessary objects were included and that the foreign key relationships were properly transported.
  Consult Documentation: Check SAP notes or documentation for any known issues related to the specific version of SAP you are using.
