There are two parallel processes B and C under process A; How can the first product flow into the B process and the third product flow into the C proces

Ummm, if you are talking about the indexing feeder, it can be found in the “Bottle Filling Layout” of eCatalog.

I’m not sure what you mean, but the GetFlowStep and SetNextFlowStep might be a solution

Thank you for your solution. The problem I encountered can be solved by your method.

Thank you as well.Tilma provides a suitable solution

Hello, How to realize that one out of every 10 products flows into B process, and the rest not divisible by 10 flows into C process?

if you want that each 10th product out of 10 flows into process B, you can use a modulo function :

If you want to have it a bit more random, like 10% of the products flow to B, you could use a uniform function:

You can find more informations about the functions in the Help File → Expressions → Functions

Thank you very much for your careful guidance！
