# Set Options These are result codes that communicate success (200) or failure (400) specific to the `Set Options` operation. Learn more about the [`Set Options` operation](/start/list-of-operations.md#set-options). * OpSuccess `SET_OPTIONS_SUCCESS` Options successfully set. * OpLowReserve `SET_OPTIONS_LOW_RESERVE` This account does not have enough XBN to satisfy the minimum XBN reserve increase caused by adding a subentry and still satisfy its XBN selling liabilities.
