Data flow loops in functional chains and op. process descriptions

[JoshWedgwood]

It is possible to create a loop, but just not on the original creation of the Functional Chain.

In the functional chain editing diagram (right click on the functional chain → Edit) you can edit the chain to create loops.

I am however also interested in the background as to why loops are restricted in the original creation.
This post seems to provide the suggested rationale.

Functional chains

Hello, One of the conditions for functional chains is: “The path of selected elements shall only have two ends, which means that it can be composed by only one branch.” I was wondering: how can I represent a function that needs two informations from two other functions to be executed. My functional chain needs two beginnings… Thank you
