Global data access issue for runnable with concurrently invoked setting true (AUTOSAR)

Not able generate code for Simulink model having runnable with concurrently invoked setting true , inside runnbale i am trying to update global data.

It is showing error , Simulink Function block 'runnable_test' may not be invoked concurrently because it accesses global data. This diagnostic is reported because 'canBeInvokedConcurrentlycanBeInvokedConcurrently' option is selected on the AUTOSAR runnable mapped to this Simulink Function.
