JDBC DELETE statement usage

Question

Hello All,
Scenario BW to ORACLE
I have  to write a JDBC delete statement  and then insert in two message mappings
This is to delete the table records before inserting
And in the interface determination, maintain order time and give the order delete first and then insert
These are all done and in the receiver CC, I have unchecked key tags mandatory. and concurrence 10
Now, I am getting an error "unique constraint violation when executed the interface
Any idea what does this error means and this error comes under delete interface execution and the insert interface portion is on hold status in message monitoring of RWB
thx
mike

Hi Mike,
   The error you are getting cannot be generated from DELETE statement.This error is given by oracle when an UPDATE or INSERT statement attempted to insert a duplicate key. For Trusted Oracle configured in DBMS MAC mode, you may see this message if a duplicate entry exists at a different level.
you have to either remove the unique restriction or do not insert the key.
This means insert operation is taking place before DELETE. You need to prevent that.
