In SAP S/4HANA Transportation Management, fuel surcharges that vary based on fuel price changes are managed using dynamic calculation methods. According to the SAP documentation:

Use an index table for the fuel surcharge charge item (A): An index table is used to store fuel price indices (e.g., pegged to 3 USD per gallon) and calculate the surcharge as a percentage (5%) of the base freight, adjusted based on the current fuel price.

Use a determination rule for the index rate table (D): A determination rule is required to select the appropriate index table based on conditions, such as the calculation date or agreement validity, ensuring the correct fuel price is applied.

The other options are incorrect:

Use the rating amount or a standard rate table for the fuel surcharge (B)is not suitable, as standard rate tables do not dynamically adjust based on fuel price indices.

Use a rate table for the fuel surcharge with calculation date as a scale (C)is not typically used, as index tables are preferred for dynamic fuel surcharge calculations.
