Security of PM2 is set to only the person who created it (ie. the default) and the security of PM1 is set to all users in our application specific group. Now,en-USTelligent Community 12https://community.appian.com/thread/10099?ContentTypeID=1Wed, 18 Jun 2014 10:09:43 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:0f1ebd60-6535-4a9e-93da-56bf65d708eaStefan HelzleI think the problem is that the users in the group are not allowed to start PM2. To handle this you have to modify permissions of PM2 to include the group or execute the sub process node in PM1 as the user who designed the model which should be either an admin or the same user that designed PM2. As soon as PM2 is started permissions are inherited.<div style="clear:both;"></div>
