Ok here is the draft of my pick ticket process flow model. I don't have permission to attach it to this thread so I hosted it on another site. Hopefully its not to small for you all to read. Let me know what you think.

Frank,
What a great start to the process flow. I noticed that when you first described the process in writing you mentioned two preconditions before a pick ticket is created by the office. Here you didn't show this. There's nothing wrong with that. The decision about where the process starts is really a judgment called based on the scope of what you are trying to improve upon.
Your first gateway (the diamond shape) is considered an "Exclusive OR" gateway. It means that you can only choose one of the alternative paths. I have a feeling that the workers may do both paths multiple times until the entire order is filled. This means you probably want on "Inclusive OR" gateway. This means the worker can take one path or the other or both. Also, you probably what to show an activity looping or sequence flow looping to repeat the steps of picking the items from stock. This is also an area where I think you need a bit more detail. Does the worker pick an item, place it somewhere and then go pick another item?
The second gateway you used is an "Inclusive OR" gateway. This means that the flow may follow one path, or the other, or both. But these two paths look exclusive. If it's the wrong material then the manager isn't going to approve it. I would also show the flow looping back on itself in the case of wrong items. We probably need to show some more detail here. What happens to the incorrectly picked items. Then I assume the worker would go back and perform the same stock picking process shown earlier in the process flow.
Third, we need to be sure that we have clearly shown who is performing which tasks so, for now, be sure to add in the activity description the person performing the activity. There are other methods for showing this but lets keep it simple for now.
I'll let you work on these things. In the meantime I will begin to form a list of questions that are going through my mind as I look at this process flow.
