Hi All,
I just completed the foundation training and the topic I struggled most was the queues and the data loading. Most likely it's me, but I'm finding it difficult to get my head around what exactly is a queue and how does loading it works, as well as its connection to a data set.
The foundation training provides an exercise that is a good challenge to digest that and as you can imagine, I'm struggling to get through it - most likely I'm doing something wrong.
I would very much appreciate if you could provide some more insight on the queues and I paste below the example provided in the training.
So, initially, the exercise has the simple ask to read the data from an Excel document, which I have done and works perfectly
and here is what the diagram looks like
The part that I'm struggling with is the exercise 11.1.3-4 where it is asking to load data into a new queue (which I have created). More specifically, I'm not sure if I execute the "pending" and "next" item steps.
Here is what my diagram looks like
The part I'm not sure about is the Decision, where the expression I have entered is this:
[Pending Items]<>0
I have also tried [Pending Items]<>"" but it didn't work either.
I'm sure that if I get my head around how queues work, I will understand and overcome this, but so far I haven't managed to.
Any help would be very much appreciated.
