Using of BAPI_RESERVATION_CHANGE

Hallo, all.

I want to use BAPI_RESERVATION_CHANGE for deleting last item in documnet and creating new item with similar data. AFAIK I can`t delete and create new item in one session. And, for begining I try to delete old position. I send the folowing parameters:

BAPI2093_RES_ITEM_CHANGE-RES_ITEM = it_main-rsnum.

BAPI2093_RES_ITEM_CHANGE-DELETE_IND = 'X'.

BAPI2093_RES_ITEM_CHANGEX-RESITEM = it_main-rsnum.

BAPI2093_RES_ITEM_CHANGEX-DELETE_IND = 'X'.

FM returm me the result message, that this position was deleted, but... ...when I call transaction MB22, I see, that checkbox `Delete item' isn`t marked...

May be someone knows what`s happend...

Thanks...
