2526466 - Dump while Implementing Note : SAPSQL_ARRAY_INSERT_DUPREC

While Implementing Note in SNOTE following dump occurs :

Runtime Errors         SAPSQL_ARRAY_INSERT_DUPREC
Except.                CX_SY_OPEN_SQL_DB

Short text

The ABAP/4 Open SQL * insert results in duplicate database records.

What happened?
Error in the ABAP Application Program

The current ABAP program "SAPLSCWC" 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 caught
in

procedure "SCWB_CINSTS_IMPLEMENT" "(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 * insert to insert a record in
the database and that record already exists with the same key,
this results in a termination.
