# IncorrectPartialFillAmount (/docs/errors/chain/IncorrectPartialFillAmount)

The `partial_fill` amount is zero or exceeds the order's remaining unfilled amount, or a full execution was submitted against an order already partially filled. Compare `partial_fill` with `order.amount` minus the filled amount recorded in `Orders`.

Declared by the `LimitOrders` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).
