ITAB_DUPLICATE_KEY

hi all

i ve designed one APD which extracts financial data. here i am storing query result in one ODS. this APD runs fine in development server but when i run it in live server it throws error : ITAB_DUPLICATE_KEY.

ShrtText

There is already a line with the same key.

What happened?

Error in ABAP application program.

The current ABAP program "CL_RSAN_RT2_DS_QUERY_RUNNER===CP" had to be

terminated because one of the

statements could not be executed.

This is probably due to an error in the ABAP program.

i am unable to understand how it runs fine in development but not in live? what could be the problem?
