PO Smartforms : EKPO, EKET looping

Dear All,

I would like to retrive data for Purchase Order smartform. I need data from EKPO and EKET, In the same node, I need details from Both EKPO and EKET. I have already looped at EKPO and retriving data for same. How and where Can I Loop at EKET for Same node ?

Can I create a 2 Loop Node, One after other ?

Should I write Program lines ?
