You add an assessorial charge to a freight order after the freight settlement document (FSD)...

When an assessorial charge is added to a freight order after the initial freight settlement document (FSD) is posted, and the change strategy is set to "Reverse and Repost with new FSD," the system handles the update as follows, according to SAP documentation:

2 FSDs and 1 credit memo in transportation management (B): The original FSD is reversed with a credit memo, and a new FSD is created to include the assessorial charge, resulting in two FSDs (the original and the new) and one credit memo.

3 FSDs in transportation management (C): This includes the original FSD, the credit memo (counted as a separate document in some configurations), and the new FSD with the updated charges.

The other options are incorrect:

1 purchase order in materials management (A)is not guaranteed, as the number of purchase orders depends on the original setup and may not change with the FSD update.

3 service entry sheets in materials management (D)is unlikely, as typically one service entry sheet is updated or replaced, not multiplied, during the reversal and reposting process.
