How to check Rebates on the R/3

Hi Friends,

Im testing a Billing Report in BW, in that rebate we have 2 Keyfigures

1.No. of Rebates Settled in Corresponding month

2. No. of Rebates Settled in Month

Now for a give Compa Code or Sales Org this report is run.

I want to reconcile the BW report with R/3.

What i need is i just know 1 Transaction in R/3 i.e VB(8 (List of Rebate Agreements), here what inputs should i give?

Please let me know.

Regards
