Hello Prasad,
you can control any change via Workflow to be notified, all you have to do is to create a new lines on SWEC with the nex records:
BANF - BUS2105 - ZWE_PR_CREATED (Create)
BANF - BUS2105 - ZWE_PR_CREATED (Modificated)
Then you extend the Object BUS2105 with this two events and then you go! yo'll have an event when you change a Network attached in to a PR.
Hope this help, a little bit late!!!.
