BAPI_PO_CREATE1 multiple schedule lines cann't create ECC500

Dear all:

I want to use BAPI_PO_CREATE1 to create more than one purchase order schedule item for a purchase order item .However, the system either posts the first purchase order schedule line or the BAPI terminates the posting with an error message. I have found SAP NOTES (828582) try to solve the problem . But it was no use.

My SAP system component information is SAP_APPL 500 0012 SAPKH50012 .

I attach test program as follows:

REPORT ZPO_CREATE.

DATA: HEADER LIKE BAPIMEPOHEADER,

HEADERX LIKE BAPIMEPOHEADERX,

EXPHEADER LIKE BAPIMEPOHEADER,

TESTRUN LIKE BAPIFLAG-BAPIFLAG,

ITEM LIKE BAPIMEPOITEM OCCURS 0 WITH HEADER LINE,

ITEMX LIKE BAPIMEPOITEMX OCCURS 0 WITH HEADER LINE,

POSCHEDULE LIKE BAPIMEPOSCHEDULE OCCURS 0 WITH HEADER LINE,

POSCHEDULEX LIKE BAPIMEPOSCHEDULX OCCURS 0 WITH HEADER LINE,

POTEXTHEADER LIKE BAPIMEPOTEXTHEADER OCCURS 0 WITH HEADER LINE,

POTEXTITEM LIKE BAPIMEPOTEXT OCCURS 0 WITH HEADER LINE,

RETURN LIKE BAPIRET2 OCCURS 0 WITH HEADER LINE.
