DT306 - Details

• The SAP error message DT306 indicates that there is an issue with a foreign key relationship in your data model. Specifically, it occurs when a field is specified in a foreign key relationship, but the foreign key is defined as a generic foreign key. This means that the system expects a more general reference rather than a specific field.
  
  Cause:
  
  Generic Foreign Key Definition: The foreign key is defined generically, which means it should not reference specific fields directly.
