You have to set Allow server objects under Document properties->Server tab.
Also same property needs to be set in QEMC->System->Documents tab
Did you check the properties of the multi box as shown in screen? May be this is the reason.
Hope this will help.
Hi All Thanks
Yes checked both - Allow server objects under Document properties->Server tab & QEMC
There is no section access
Properties for options also checked
other objects i can able edit apart from Multibox object.
