  Debugging: If you have access to the ABAP code, use the debugger to trace the execution and identify where the parameters are being set. Check if the parameters being passed to the join are correct.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for the specific join types and their parameter requirements. This can provide clarity on what is expected.
