Hi,
Let me try to explain with the same example:
In your pricing procedure (Lets assume)
Step 10 : PR00
Step 20: KA02
Step 30 - Net value -1
Step 40- K005
Step 50 - Net value 2
Condition records of VK11
PR00 - 100 INR
KA02 - 5%
K005 - 5 INR
Sales order with one line item - Qty1
PR00 - 100
Ka02 - 5% = 5 INR
Netvalue-1 = 95
K005 = 5 INR
Net Value 2 = 90 INR
Your net value 2 will be shown as your order line item net value = 90 INR
Its all depends on how you want display your net values (if you want to have different net value figures after some couple of discounts or you want to display one net value after calculating all discount values) It also, depends on business scenarios and pricing logic. There is no thumb rule that you have to follow exactly what i have mentioned in the example.
You can even maintain one Net value step after KA02 and K005.
At the end what is showing in your sales order - net value field (VBAP-NETWR) is important.
Hope its clear to you now,
Let me know if you need any further clarification.
