Thanks Mr.JP
Error analysis:
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_OPEN_SQL_DB', was not caught
     in
    procedure "SD_PARTNER_UPDATE" "(FUNCTION)", nor was it propagated by a RAISING
     clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    If you use an ABAP/4 Open SQL array insert to insert a record in
    the database and that record already exists with the same key,
    this results in a termination.
    (With an ABAP/4 Open SQL single record insert in the same error
    situation, processing does not terminate, but SY-SUBRC is set to 4.)
when i comment  partner  details  it works  but
Iam not  getting  quantity  and partner  details   so  how to pass  Partner  Details   and item quantity
to updated  existing line item number.
