SendToPort First Available - Port num?

Hello!

I was wondering if there is any way to know exactly which port is selected after returning 0 on the SendToPort code at a Processor.

The thing is I need to know as soon as it returns 0 to save it on a Global List for future logic... I thought about putting it at the Use Transporter Custom Code but it doesn't do it immediately... any ideas??

Thanks for your time! 🙂

You can only identify the Port Number after the item has actually left the Object in the On Exit Trigger oder Event.

Hi @joerg.vogel Thanks for the answer! Yes, I tried that, but in my case the item takes a little longer to be on Exit, and I need to save the port number right away. So in case there are other items with the same type as that one on other processors, they all go to the same port as that one that has decided as first available, does it make sense?

@ana.pc2, the return value of send to port is data in scope of items. If you decide to return first available, then this parameter will be accomplished if the item actually is able to leave the object. And at this time the port is chosen. You can’t predict the output port if the send to port is set to first available. It is an option to accelerate releasing items. You can set a single discrete output port, but then an item stays as long as this output port gets available.

You can accept this fact, that you can not predict a port with first available or choose a discrete direct value for send to port!

@ana.pc2, now you extended your question to push items to a processor still processing a distinct item type. As I said you can‘t predict the first available port. But you can check in send to port if an output port object processes the same item type and set this same output port as the return value. Please ask this as a new question and describe precisely the circumstances you want to achieve in your logic! Thanks. Jörg
