Hi Sree,
my problem is to determine the position reference during printing invoice.
If in the copy control from sales/delivery document to invoice the indicator TVCPF-EXPIM (Determination of export data in billing document) is settled to B the EIPO-EXPOS is VBRP-POSNR, but if is blank is correct what you said: EIPO-EXPOS = VBRP-VGPOS.
Now I solved my problem reading customizing, but this is not a good solution. I think somewhere there is a link (another table or a copy of EXPIM indicator?).
Bye
Gabriele
