  Solution:
  
  
  Define Navigation Link Field:
  
  Go to the data model configuration in the SAP system.
  Identify the header table and check its properties.
  Ensure that a navigation link field is defined. This field should typically be a key field that relates the header to its detail records.

  Ensure that the relationships are correctly defined and that the necessary fields are included.
  
  
  
  Update Data Model:
