Output problem in report

Dear gurus

My requirement was to upload excel sheet and update the data in to Z-table .
It is done now. But now , I wanted to show error message if the data is being already there.
Here's the code as-
LOOP AT it_tab INTO wa_tab.  
ZEXCEL-EMPNAme =     wa_tab-EMPName.  
ZEXCEL-Designation = wa_tab-Designation.  
ZEXCEL-Salary = wa_tab-Salary. 
  INSERT ZEXCEL. 
  if sy-subrc <> 0.    
MOVE-CORRESPONDING wa_tab to wa_error.      append wa_error to it_error.     
clear wa_error.  
endif.   
clear wa_tab.
ENDLOOP. 
if it_error is initial.  
message 'all data updated Sucessfully'  type 'S'.
else.  
loop at it_error into wa_error.    
write:/ 'Already Exist',wa_error-EMPName. 
  endloop.
endif.
output is as -


Can you please modify my code to get my requirement.
help will be appreciated.

Thanks
