Execute the teststep - Read the excel sheet first value for single execution

Hi All,

In my excel sheet I have 10 values in one rows

 

While executing my teststep I need get first value only from excel sheet. after all testcase execution, while I am executing one more time that time need to get the second value from my excel sheet.

 

Normally datadriven approach while executing it will pass all the value in my first execution but I need to pass only one value in one execution

 

I need to achieve this from soapui with groovy scripting

 

I need your guidenece and reference too
