i guess i am confused by the logic here. i agree that you need to use so_vtweg-low, AFTER you read the first table line, but its the logic of the if statement that has me puzzled.
if SO_VTWEG-LOW <> '70'.
elseif SO_VTWEG-LOW <> '80'.
ELSEif SO_VTWEG-LOW <> '90'.
else.
PERFORM F005_BUILDFC USING '30' 'NETWR' 'ITAB2' TEXT-024 '15' ''.
ENDIF.
after the first line, everything other than a '70' will have triggered the execution of the code in the first section. after the first elseif, everything except '80' will trigger the code in that section, including 70... so, whats left? i dont think you will ever get to the second elseif or the final else.
