Error in the ABAP Application Program
The current ABAP program "SAPLV05I" had to be terminated because it has
come across a statement that unfortunately cannot be executed.
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 cau
     in
    procedure "SD_PARTNER_UPDATE" "(FUNCTION)", nor was it propagated by a RAI
     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
Kindly suggest as to how to resolve this asap.

These Kind of Errors Generally Occor for the wrong maitnaince of the partner functions. If you are using any user exits to detremine the partner functions. check the logic in that routine.
Because we do frequently get this error, but only if we hae not maintained as per the rule written in the  user exit..
The USer exits for partner Determiantion to check is Function Module EXIT_SAPLV09A_003.  THis gets activated, if you have give the source parner function as "X/Y/Z" in your partenr determiantion procedures.
