Structuring of two Extractors 2LIS

I'm having a doubt,

What do the structuring of two extractors 2LIS, so I will hold a parade on the machine.

The extractors that I will undertake the structuring are:

--> 2LIS_11_VAITM

--> 2LIS_13_VDITM

The question is, can achieve the structuring of these two extractors in parallel? Or I have to carry out the structuring of a structure and then the other?
