When you setup your physical warehouse and setup AX to match the way you operate there are a lot of parameters that you have to select from. One example is the patterns of how you execute work in the warehouse most efficiently. For example do you pick based on the orders or do you pick based on items. There are many other options in how you might want to optimize the processes. When you create work in the warehouse you will want to match it to the way you work. For example in the shipping process you will release to warehouse either through the screen options or on the load which will execute the wave if you have that setup for example to process. The wave will intern create the work in the based on the work template. It is here that you might want to have a look at options for grouping and splitting work.
Here is a quick example in this case grouping by sales order.
