A flowitem in my model can get processed at either M1C1 rough or M1C2 rough and then needs to be processed at M1 spectrometer.
Once a flowitem enters M1C1, I want to close the input of M1C1 and not allow another flowitem to enter until the first flowitem has been processed at both M1C1 rough & M1 Spectrometer and passes back thru M1C1 and out to Tested drive queue.
I cannot get the closeip logic to work. Any suggestions?
