  The SAP error message SMT010 ("Input parameters must be assigned to fields of source structure") typically occurs in the context of data transfer or mapping processes, particularly when using the SAP Data Transfer Workbench or similar tools. This error indicates that there is a mismatch between the input parameters provided and the expected fields in the source structure.
  Cause:
  
  Field Mismatch: The input parameters you are trying to map do not correspond to the fields defined in the source structure. This could be due to incorrect field names, types, or missing fields.
  Incorrect Mapping: The mapping configuration may not be set up correctly, leading to an inability to assign input parameters to the expected fields.
