How to start BPM Process in Netweaver CE 7.1

Hi,

since 2 Month i am trying to use SAP Netweaver CE 7.1 EHP1. I found a lot about modelling of business process with process composer.

In my company we are often using SAP Standard Programs/transaktions, thats why I want to start a SAP Netweaver BPM Process from SAP Backend. I think there are more than one way. May be someone can tel me one easy way.

The following systems are available in my Landascape:

- PI 7.1

- ERP 2005

- CE 7.1 EHP1 with ESR

Does someone have an idea how to start the BPM Process or how to trigger start event from Backend?

Greetings,

Manuel
