Problem using Data source groovy

Hello everybody, i have that situtation. 

 

I'm using a Data Source groovy, so i need to get all data using a "while or each" instrucction at one interation. I tryed a lot of method, but whaever if i have 1, 2, 3 or any iteration loop allway i got it the last one, so i need to get all of them in a data log. 

 

Other thing that i see is, each new execution reset local or global variable then i can't use it to get a external control at every executions

 

the delivey time for my client of these test case is very close, so  I appreciate your recommendations.

 

i share u can screenshot about my code.
