For the process Check for Room Availability on the parent diagram, we must specify that it is decomposed by a child. (If we do not specify this, an error will come up during the simulation asking you to define a service time profile for it when we run the simulation.)
1 Open the definition of the process Check for Room Availability, go to the Sim Child Diagram tab, and specify the Child Diagram to be Simulated – click Choices, and then drag in the diagram name Check for Room Availability Simulation.
2 Toggle ‘on’ the choice Include child Diagram in simulation.
