  The SAP error message TR186 indicates that there is a mismatch in the name range allocation for a foreign key table in the context of a transport request.

  Adjust Foreign Key Table: If the foreign key table is incorrectly defined, you may need to adjust its definition to align with the naming conventions and range allocations.
  Consult Documentation: Refer to SAP documentation or consult with your SAP Basis team to understand the specific naming conventions and range allocations in your system.
