BAPI to update SO schedule line

Hi Expert,

  i would like to ask is there any BAPI behaviour same as SO item availability?

  Currently we are using SAP BAPI "BAPI_SALESORDER_CHANGE"  to change the schedule information.

  We find they it is not possible to insert an item with Order Qty 0.

  but if we use SO item availability in VA02, it will able to create the schedule line item 2 , 3 or more with order Qty 0.

  attached document is the VA02 screen capture for it.

Thanks
