Hello Raymundo,
I have tested a service using LM01 transaction - I created the ITSmobile service following SAP KBA 2242078. The system used runs kernel 7.42 pl 424 (the latest one available) and SAPKB74010. When I killed the session in SM04 and clicked on a button of the menu, I got a page:
"...
400 Session timed out - please log in again
Error is logged with Tag: {000403e0}
..."
So, the scenario is working as expected.
Kind regards,
Cris
