  Review MBO Configuration: Check the configuration of the MBO in the Data Model. Ensure that only one header table is defined for the MBO in question.
  Modify Data Model: If multiple header tables are defined, you will need to modify the data model to ensure that only one header table is associated with the MBO. This may involve:
  
  Removing the additional header table definitions.
  Adjusting relationships and dependencies to ensure data integrity.
  
  
  Consult Documentation: Refer to SAP documentation or guidelines regarding MBOs and their configuration to ensure compliance with best practices.
  Testing: After making the necessary changes, test the configuration to ensure that the error is resolved and that the data replication works as expected.
