Count on a header table including the line data also in the query

Question

Hi,
I have a requirement to develop a report which shows the metrics on supplier. I need to find the total PO's for this supplier that are matched to invoice
report has to have toatl#ofpo's, #invoice, total_inv_amt and total_po_amt, total_tax_amt with item numbers also with in a time period. So my question is how can we achieve this I have this below query whih gives all the data but not sure how to get the counts with this. Any ideas
SELECT hou.name,
pov.vendor_name,
api.invoice_num,
api.invoice_id,
invoice_date,
gl_date,

apid.unit_price inv_price,

and msi.organization_id = 1) item_num,

Hi,
The sounds like a job for the COUNT function. That's all I can say with any confidence based on the information you gave.
If you want to see, on each row of output, how many of the rows with the same value of api.invoice_num have a value for poh.po_header_id, the you can use
COUNT (poh.po_header_id) OVER (PARTITION BY api.invoice_num)   AS po_cntI could give much better directions if you could post a little sample data (CREATE TABLE and INSERT statements), and the results you want from that data. I realize that's hard with so many tables. Even seeing some of your current output, and the desired output, might help.
