Execution Control 
Execution control enables you to control the execution of tasks in the following:
· Predefined zones of a site, preventing resource bottlenecks and ensures the workability of the semi system-guided mode of task selection
· Predefined nodes of a site, preventing resources from executing tasks that involve taking handling units to nodes with insufficient capacity
You have defined Execution Control Objects (ECOs) in Customizing for Logistics Execution ® Task & Resource Management ® Control Data ® Execution Control, and have enabled the ECOs using the TRM monitor.
The system determines whether or not an ECO is available by comparing the number of constraint objects (tasks, resources or handling units) subscribed to the ECO with the ECO’s allowed capacity.
After a resource selects the system-guided option using its presentation device, Task Management obtains a list of all tasks that the resource is capable of doing and eliminates those tasks that are subscribed to unavailable ECOs.
