• What is the cause and solution for SAP error message DT835 - Multiple foreign key definitions were found for field & ?

  The SAP error message DT835, which states "Multiple foreign key definitions were found for field &," typically occurs when there are multiple foreign key relationships defined for a single field in a database table. This can lead to ambiguity in data integrity constraints, as the system cannot determine which foreign key relationship to enforce.
  Cause:
  
  Multiple Foreign Key Definitions: The primary cause of this error is that the field in question has been defined with more than one foreign key relationship in the data dictionary (DDIC).
  Inconsistent Data Model: This can happen due to inconsistencies in the data model, such as when a field is intended to reference multiple tables or when there are overlapping definitions.
  Table Design Issues: It may also arise from poor table design or changes made to the data model that were not properly reflected in the foreign key definitions.

  Review Foreign Key Definitions:
  
  Go to the Data Dictionary (transaction SE11) and check the table definition for the field that is causing the error.

  Check Related Tables:
  
  Verify that the tables being referenced by the foreign keys are correctly defined and that the relationships make sense in the context of your data model.
