We want to manage split advance payments (multiple advance payments) on a per‑order basis.

However, the situation is as follows

・There is no functionality for managing split advance payments.

・The system does not provide a standard feature for dividing advance payments into multiple installments.

・Advance payments cannot be collectively managed on a per‑sales‑order basis.

Please implement the following

・Registration of split advance payments at the sales‑order level

・Management of advance payment balances by sales order

・Automatic clearing of advance payments at the time of revenue recognition

 Schedule management for split advance payments (e.g., 30% → 40% → 30%)
