Hi Pavan,
In some cases you need to fetch all the KEY fields (In this case BELZEILE needs to be fetched). If you Rephrase your select query to
Data : c_1001 type e_preis value '0000001001'.
SELECT belnr BELZEILE nettobtr preisbtr INTO TABLE i_price
FROM dberchz3
FOR ALL ENTRIES in i_erch
WHERE
belnr = i_Erch-belnr and
preis = c_1001.
I hope this should solve the issue.
