how to get stack configuration file for EHP1 for PI 7.1

Hi Experts

I am doing EHPI Installation.

my source system is PI 7.10 at SP stack 09.

while i have to go to target PI 7.11 Stack 04.

at stage of stack configuration it asks for the stack configuration file location.

How to get this file.

I saw the old posts.

It says it gets generated while downloading from solman.

I have downloaded the PI 7.11 SP04 by solman-> downlaod manager-> kept on my serevr at my location.

But in solman serevr trans/eps/in I cant find the stack.xml file.

I am a bit confused with so many notes and lost direction.

Can some one guide me out of this lost world.

Thanks in advance.

Regards

Pooja
