  Data Inconsistency: There may be inconsistencies in the master data for the materials involved, leading to this error.
  Missing Assignments: The assignment of materials to MRP sets may not have been completed during the setup or may have been inadvertently removed.
  
  Solution:
  
  
  Check MRP Set Configuration:
  
  Go to the MRP set configuration in SAP (Transaction code: MD61 or similar).
  Verify that both materials (Material &1 and Material &2) are included in the same MRP set.
