Hi @Shanmathi ,
I assume you have three values in the excel and you are entering those values one by one using for each row loop in the web application and for each and every value enter your saving by clicking save button in the website am I right.
If my understanding is correct then please follow the suggestion below
Debugging with breakpoint will slow down your automation execution pace so your getting enough time to click save button so all the three values saving in the website.
As suggested above try to use some delay activity to click save button or
Some websites will disable the save button until you enter the Value properly in the field and also it depends on the website loading the ui elements so try to use the element exist property for the save button and check in ui explorer that is there any attribute which is telling that save button enabled. In this way we can go with conditional delay instead of hard coded delay.
Please give it a try. Thanks
