title: PowerDesigner: How to get reason for "No data can be generated for the table xyz"
body: <p>I've reverse engineered a database via PowerDesigner. Now I want to create test data for this database (lot of tables, lot of references...) but failing during process with message: </p>
  
  <pre><code>No data can be generated for the table xyz
  </code></pre>
  
  <p>Unfortunately xyz are most of my tables of the database and I'm seeking for a reason, why it's not able to do so. </p>
  
  <p>The tables are using a PK of type uniqueidentifier set via newid(). Also it's highly nested in stricture. So one entry on top might need 30 or 40 entries in other tables in sum -- but the Impact and Lineage Analysis is finding them so I can browser them from there. </p>
  
  <p>When checking model I've got a number of warnings about missing indexes etc. But no error message.</p>
