Invoice: reading VAT amout per item

Question

Hi there,
can anyone tell me how to read the VAT amount for each item while processing an invoice in a form (smartforms)?
The print program provides the following structure: LBBIL_INVOICE. This structure includes obviously all information about an invoice. But when I want to read LLBIL_INVOICE-IT_KOND-KBETR there is no value. In VF03 there is a value (e.g. 16%). I thought to use table KONV but I don't find a link between the invoice item and the condition record (KONF-KUMH) number in KONV-KNUMV. Perhaps this way is wrong anyway.
Any idea?
Values for VAT are available on header level but I need them on item level because there may be different values (7%, 16%, etc.) for each item.
Thanks for your help!

Answer 1

My previous post was for the tax VALUE.  If you want the tax RATE, and it is not coming through into IT_KOND, then its probably not flagged to be printed at the item level in the pricing procedure. 
In the pricing procedure you can set for each condition the following print options:
     It was not printed
X     Printing at item level (previous procedure)
S     Printing at totals level (previous procedure)
A     Total: General
B     Total: if value <> zero
C     Total: if value <> previous value
D     Total: if value <> zero and value <> previous value
a     at item: General
b     at item: if value <> zero
c     at item: if value <> previous value
d     at item: if value <> zero and value <> previous value
It probably needs to be set to <b>a</b>.
Cheers,
