ABAP Proxy setup SAP to PI (7.31 single-stack)

Hi,

I am trying to setup the proxy communication from SAP to PI (7.31 single-stack).

I went through this very good blog by Michal on how to set this up.

http://scn.sap.com/people/michal.krawczyk2/blog/2012/01/19/michals-pi-tips-how-do-you-activate-abap-proxies-with-aex--simplified-version

I created the outbound proxy from my Service Interface and activated succesfully.

Now when i test i get the following error

GET_BUSINESS_SYSTEM_ERROR An error occurred when determining the business system (COMMUNICATION_ERROR)

When i do SLDCHECK i get the following error (According to blog it shouldnt be necesary to create SAPSLDAPI)

What am i missing here?
