Chapter 6 Withdrawing Steps From the Procedure : Defining a Withdraw Action on a Sub-Procedure

Defining a Withdraw Action on a Sub-Procedure

If a sub-procedure case is withdrawn by the parent procedure case it will be closed immediately. In the diagram below, if step S2 is released before the sub-procedure called by SUB1 is completed, then S2 will withdraw SUB1 causing the sub-procedure case to be terminated prematurely.

When a sub-procedure case is terminated prematurely, no data is transferred back to the parent procedure and if the sub-procedure calls any further sub-procedures, these will also be closed.
