ALV Report heading

Hi,

When I am display data using ALV I am not able to display some fields data in the output it's like this if I have f1,f2,f3,f4,f5 i am able to see the data only for f4 and f5 but not able to see the data of f1,f2 ,f3 even then I have data for that fields

these fields(f1,f2,f3) are sorted and subtotal fields can any body tell me what's the wrong here.

Thanks&Regards

Mahesh
