Hi Ranjan,
As of my knowledge, there is no direct method to calculate Row wise totals, I believe.
If your requirement is as follow,
Col1 Col2 Col3 Col4
2 5 6 13
4 5 3 12 (Col1 + Col2 + Col3)
Then before displaying the output just loop the internal table and calculate the Total as above and place that value in last column and modify internal table.
If user doesn't want it by default and he wants to see that whenever he required, just make one default layout without total Column.
If my understanding was wrong, hope you can elaborate your query.
Thanks & Regards,
Vijay
