Integrated ITS: multiple sessions and locking issue
We are upgrading to ECC 6.0 from 4.6C and have Integrated ITS turned on. We have built a custom PZM3 as one entry and exit point for our ESS services. But we have issues with session management when navigating between some services like PZ14 and PZ02. The PZ14 session and the corresponding lock are not released upon going to the PZ02 service directly. But this happens for only some services. If you navigate between PZ02 and PZ12 it works fine. I followed the instructions of note# 959417, but it didn't work. Not only it is causing locking issues, but also memory usage issues as multiple user sessions are being created on the server. I did check some of posts similar to this one, but the issue still persists.
Our WAS release: 7.00; ABAP support package: SAPKB70009; Patch level: 75.
I would appreciate if anyone could shed some light on this issue. Thank you for your time and consideration.
