Run time column attach to apex report

Question

Hello everyone,
can it be possible to make a function in a apex which will return a column value in report, like wise we use in report builder. I know we can do this directly in report query... however i want to make a some process may be, through which i can get a column value.
My requirement is.... i am having a PO report where columns are Header_id, Segment1, Vendor_id, Vendor_site n Amount.
I can have every column data from PO_header_all except amount for which i need to use.. PO_lines_all whose would be depend on header_id.
Now.. i can do this directly in query.. but here i don't want to.. use a po_lines_all in report query. I want to call the Amount column attach at run time to report.
Pls tell me how can i do this??
I don't know whether it is possible or not... if it is then how can i do this.
Regards,
UKJ

Hi,
Do you mean something like:
SELECT H.HEADER_ID, H.SEGMENT1, H.VENDOR_ID, H.VENDOR_SITE, SUM(A.AMOUNT) TOTAL_AMOUNT
FROM PO_HEADER_ALL H
LEFT OUTER JOIN PO_LINES_ALL A ON H.HEADER_ID = A.HEADER_ID
GROUP BY H.HEADER_ID, H.SEGMENT1, H.VENDOR_ID, H.VENDOR_SITEThis will return the header_id, segment1, vendor_id and vendor_site values from po_header_all and a total of amount from po_lines_all
