&lt;p>&lt;em>Created by Patrick Schiefer, Described by Patrick Schiefer&lt;/em>&lt;/p>
&lt;h2 id="abstract">Abstract&lt;/h2>
&lt;p>The goal of this pattern is to control the flow of multiple processes&lt;/p>
&lt;h2 id="problem">Problem&lt;/h2>
&lt;p>Sometimes its neccassary to perform multiple processes in Business Central, for example you want to post more than one order or before you post an Order you also have to post a purchase order this often leads to spaghetti code with big if else structures, which is not easy to read&lt;/p>
&lt;h2 id="description">Description&lt;/h2>
&lt;p>The pattern is ideal for executing several independent processes in succession. Since the processes are independent, each process must take care of error handling itself.
The command queue should not be used to control a single process. Also it is important to know that the queue is just in the memory so if the service gets restarted the queue is gone and has to be rebuilt.&lt;/p>
&lt;h2 id="the-pattern">The Pattern&lt;/h2>
&lt;p>To structure this problem we can use the &amp;ldquo;Command Queue&amp;rdquo; pattern. The pattern consist of two main parts the queue and the command interface&lt;/p>
&lt;p>&lt;img src="queue.png" alt="image">&lt;/p>
&lt;p>First the command interface, it only has one procedure to execute the command&lt;/p>
