I think we might want to consider a different approach:

• Quickly we can have a high number of transactions and we would like to avoid to recalculate / reprocess all transactions and the amortization schedule
• We should focus on the changes in the transaction allocations only

What if:

• Transaction was reversed:
  • transaction reprocessing should only happen if
    • reverted transaction was repaying any charge -> The next upcoming transaction(s) need to reprocessed till charge is repaid by them, the rest of the transactions does not matter.
    • otherwise it does not matter -> No transaction reprocessing needed!
• Backdated transaction:
  • transaction reprocessing should only happen if
    • backdated transaction needs to repay any charge -> The next upcoming transaction(s) might need to be reprocessed as they might not or with different amount to pay charges from now.
    • otherwise it does not matter -> No transaction reprocessing needed!
• If no charges were added on the loan, there is no reprocessing needed at all!
• If reprocessing was needed, we should have the "new" allocations of the involved transaction(s) and based on this amortization schedule / breach schedule / delinquency schedule balances might need to be updated. But only with the delta (difference). No need to recalculate everything, but only with impacted parts.
