Reading record line by line

Hello,

I have a requirement where one task gets me list of approvers. Lets say there are 5 approvers and now read this list of approvers one by one and email them. So the email goes to 1st approver and he approves, then read second record and email him -> approves and then read the 3rd record and email him. and so on till the last.

My ques is how to READ already populated table one by one ? Is there anything like sy-index which will let me read the record in sequence or i need to have a counter of my own ? I am using untill loop where i am planning to implement this scenario.

Can you please help me in this regard.

Regards,

Anurag
