Hi,
Just CHeck this Documentation from SAP :
... ACCEPTING DUPLICATE KEYS
Effect
If a line cannot be inserted, the system does not
terminate with a runtime error but only sets the return value SY-SUBRC to 4. All other lines are inserted after the command is executed
i.e. so as to just avoid the dump we can use this syntax.
But we cannot insert duplicate records in a table.
Any ways if you have to insert duplicate you have to change your primary key's and table design.
