As described in "8.3.2 Transaction Structure" and “8.3.3 Delta Quantity Change Flag (delta_quantity_c)” on J-GATE3.0 Connectivity Manual [Business Message part], when using the absolute quantity method, set "1" to delta_quantity_c (Delta Quantity Change Flag) and the order to be altered will be proceeded as Absolute Value.
However, when using the delta quantity method, set "2" to delta_quantity_c (Delta Quantity Change Flag) and the order to be altered will be proceeded by calculating delta quantity.
If the number other than “0” was entered in balance_quantity_i (Remaining Quantity Check), the order will be modified only if the remaining quantity of order and value were identical.
