Hello guys,
I need to find a solution for this issue.
I have 4 different flowitems (but i think it's not important), they goes to Processor1 for the first time then elevator transport it in Queue2 and same elevator1 allows to carry towards Processor2, after the process of the flowitem, it return again to the Processor1 for the second time using elevator1 to transport, when the process finish the flowitem goes to Queue9.
The problem in this system is the sequence of the flowitems, I have to make sure that until queue2 is saturated processor 1 does not take flowitems from queue1 and wait to process the outgoing flowitem from processor2, so subsequently direct it to queue9 and finally be able to take a flowitem from queue1.
