Tracing of mobile device user

Hi All,

We required to find a trace for particular user session who is using Ware house mobile device.

When user has performed action using WMDP we have collected trace using data collector but at that time we got almost
25 user sessions in that trace, the user which we are trying to located cannot be found.

I want to know how WMDP is connecting with AX when passing data from mobile device to AX?
I am suspecting communication between AX and WMDP is through service account?
Any help would be appreciated.
