SQL-Server drill down in an other table (group by) - sql

Question

OK, I'm quite new to SQL and didn't get to much training!
I'm using SSMS to create stored procedures and open them in Excel.
The code below work just fine, but I need to add a drill down to get more info on some lines.
We need to follow what was invoice and paid on a batch of contracts for our project. Each contract have multiple lines with a description and a couple of other fields(reference, line #, G/L # etc). Plus we have the value of the line, the amount that was invoice for this line and the amount that was paid.
Main table 'CSCOMVTL' have the basic infos including the base value and the invoice amount, but not the paid amount.
'JRAPRVTL' is the list of all invoices with; invoice no., invoice date, invoiced amount and paid amount that we may need to see.
So for each base line, we need a +/- button to show/hide details of the invoice.
Invoice amount and paid amount could be from a rollup, but the number and date won't be on the parent line. If they could be in the same column as other field not needed it would be great, but I could live with 2 extra columns.
Thanks!

First off, take the time & learn SQL. It's an invaluable tool in your toolkit!
Okay, enough of the lecture. In looking through your code, you don't seem to really need the temp table #rpt, you just need to understand JOINs. Hopefully this SQL will get you what you are looking for:
SELECT vtl.ROW AS Ligne, vtl.DETAILCHANGEORDERCOU AS Lein, vtl.ACTIVITY AS Act,
vtl.DESCRIPTION AS Descr, vtl.AMOUNT AS MntBase, vtl.INVOICE AS MntFact,
mac.CHANGEORDERNUMBER AS Modif, mac.DESCRIPTION AS Descr3, mac.CHANGEORDERCOUNTER AS Lien2,
sum(jrap.payment) AS MntPy
FROM cscomvtl AS vtl
LEFT OUTER JOIN cscomac AS mac
ON vtl.detailchangeordercou = mac.counter
LEFT OUTER JOIN jraprvtl AS jrap
ON vtl.row = jrap.poline
WHERE projectnumber = #projet AND LTRIM(RTRIM(ponumber)) = #contrat
GROUP BY vtl.row, vtl.detailchangeordercou, vtl.activity, vtl.description, vtl.amount,
vtl.invoice, mac.changeordernumber, mac.description, mac.changeordercounter
You will likely have to tweak it to fit what you're trying to do in Excel, since you really didn't give much to go on there.
