title: Powercenter - concurrent target instances
body: <p>We have a situation where we have a different execution order of instances of the same target being loaded from a single source qualifier. 
  We have a problem when we promote a mapping from DEV to TEST when we execute in TEST after promoting there are problems.</p>
  
  <p>For instance we have a router with 3 groups for Insert, Update and Delete followed by the appropriate update strategies to set the row type accordingly followed by three target instances.</p>
  
  <pre><code>RTR ----&gt; UPD_Insert -----&gt; TGT_Insert
        \
         \__&gt;   UPD_Update -------&gt; TGT_Update
          \
           \__&gt;  UPD_Delete ---------&gt;  TGT_Delete
  </code></pre>
  
  <p>When we test this out using data to do an insert followed by an update followed by a delete all based on the same primary key we get a different execution order in TEST compared to the same data in our DEV environment.</p>
  
  <p>Anyone have any thoughts - I would post an image but I don't have enough cred yet.</p>
  
  <p>Cheers,</p>
