Process message option does not exist on context Menu for Xstep PI sheet

Hello Expert,

Recently we have implemented context menu for our client and it is working absolutely fine with containing all functions on right click option for non Xstep PI sheet. We came across an issue, as this context menu is missing process message function on Xstep managed PI sheet whereas getting all functions on non Xstep PI sheet. I have checked all config and SAP notes which was implemented but didnt get an exact clue why only 'Process message function' does not appear on Xstep PI sheet even after creation of new process message also.

Appreciate if anybody has come across such issue

Thanks,

Mayur.
