ABAP QUERY taking much time after ERP Upgrade from 4.6 to 6.0

Hi All,

I have an ABAP QUERY which uses the INFOSET INVOICE_INBOUND and the USER GROUP InvoiceVerif. The INFOSET is using the tables RBKP and RSEG connected using a JOIN on BELNR and GJAHR fields.

The query was working fine in 4.6 C Version. Now the system has been upgraded to 6.0 version.

Now it takes so much time that the processing is not getting completed. Do we have to make any changes to the existing queries for an upgrade?

Thanks a lot in advance.

Gautham.
