DI773 - Details

• The SAP error message DI773 indicates that a basis table is being referenced more than once in a data dictionary object, which can lead to inconsistencies or conflicts in the data model. This error typically arises during the activation of a data dictionary object, such as a table, view, or structure.
  
  Cause:
  
  Duplicate References: The most common cause of this error is that the same basis table is being referenced multiple times in the definition of a data dictionary object.
  Incorrect Table Relationships: If a table is incorrectly defined to have multiple relationships to the same basis table, it can trigger this error.
  Inconsistent Data Model: Changes in the data model that have not been properly reflected in all related objects can also lead to this error.
  
  
  Solution:
  
  Check Data Dictionary Object: Review the data dictionary object (table, view, or structure) that is causing the error. Look for any duplicate references to the same basis table.
