Duplicate Invoice FB60.

Hi Friends,

Actually in 4.5 version T.codes : MRHR, MRHG are working fine for Vendor Invoices,I didn't get any duplicate invoices Because they writen some custom program...

But in 6.2 version MRHR and MRHG are no longer use..here we are using through FB60/FB65.

IN FB60 standred program

SAPMF05A --> INCLUDE MF05AI00

--> MF05AI00_BETRAG_PRUEFEN

--> call function 'FI_DUPLICATE_INVOICE_CHECK'

Here My question is : By using this am getting the duplicate invoices so i need to avoid the duplicate invoices.....

My assumption is : I need to change the FM ?????

Could you plz help me anyone regarding this issue.

If possible send the code for changes the FunctionModule.

Thanks,

kumar.
