Issue when deploying BPM process in NWDS

Hi everybody,

I'm new to developing BPM processes in NWDS and I'm facing an issue when deploying. 

First of all, I created a simple BPM process using version of NWDS SAP NetWeaver 7.3 SP08 PAT0005 (pretty old...) but I decided to upgrade the version to avoid the problem of the type XI protocol not appearing in the Service Reference (based on William Li article). So, I didn't even try to deploy.

Then I upgraded to the latest version of NWDS and had the problem when deploying. It was understandable because my NWDS version was newer than the SAP PI version. The message was clear. "Your compiler version is 4.3 and your runtime version is 4.0... go through the Note 1600131 - NetWeaver BPM: BPMN compiler compability list..."

The thing is that, even after going through the note, I'm not really sure of which one among all the available versions of NWDS would be the appropriate version and trying to test one version and then another and so on is kind of a nightmare...

This is my software build information (SAP PI)

And my BPM-CORE component version:

1000.7.31.1.0.20110918015700

Any help is appreciated,

Thank you all!
