Append error message to itab and download to excel

Question

Hi GURUS,
Need urgent help
I have an internal table  ( say columns a,b,c)
I need to validate the fields and upload to ztable.
If any of the row fails during validation. I need to write a corresponding message and append it to the contents of itab--output itab( same as itab) and then download the output internaltable
Please send some code, if any one has implemented
THanks in advance
