In my program i have written the code as
V_d= 'no data present'
loop at it_sak where mitkz NE space.
concatenate v_dit_sak-skb1 into v_d seperated by space.
if v_a= 'x'.
message i001 with v_d.
as its coming under the loop if in the table if atleaset one value of internal table it_sak has some value in mitkz then only the error message is getting displayed.Now in my case by skipping that particular contents the other values should be displayed.How to do it?
