  The SAP error message RSDHA275, which states "Mapping of input fields missing," typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the mapping of input fields in a transformation or data flow. This error indicates that the system cannot find a proper mapping between the source fields and the target fields in the transformation.
  Causes:
  
  Missing Mapping: The most common cause is that the transformation does not have a defined mapping for one or more input fields from the source to the target.
  Field Name Changes: If the source or target data structure has changed (e.g., field names or data types), the existing mapping may no longer be valid.
  Transformation Errors: Errors in the transformation logic or configuration can lead to missing mappings.
  DataSource Issues: If the DataSource is not properly configured or activated, it may not provide the necessary fields for mapping.
  Inconsistent Data Types: If the data types of the source and target fields do not match, it can lead to mapping issues.
  
  Solutions:
  
  
  Check Transformation Settings:
  
  Go to the transformation in the SAP BW system and verify that all input fields are correctly mapped to the corresponding target fields.
  Ensure that there are no missing mappings for any required fields.

  Check if the DataSource has been updated to reflect any changes in the underlying data structure.
  
  
  
  Check for Field Name Changes:
  
  If there have been changes in the field names in the source or target, update the transformation to reflect these changes.
