title: Method 'DUMPSETSET_GET_ENTITYSET' not implemented in data provider class
body: <p>I created a function module and gateway service that reads data from SNAP_BEG table which is stores DUMP issues. There is no any error except that. </p>
  
  <p>When I try to use link as /DumpsetSet I get 
  "Method 'DUMPSETSET_GET_ENTITYSET' not implemented in data provider class" </p>
  
  <p>I found that how to redefine implementation but what code should I write in it? I cant find an example for this. Function module code is.</p>
  
  <pre><code>SELECT * FROM SNAP_BEG INTO TABLE ET_SNAP_BEG.
  </code></pre>
  
  <p>Or I just need to use something else?
  What type of link should I use. I got one more project someoneelse done and I cant see difference in implementation from mine.</p>
  
  <p>Edit: I can get firs record that program find by /DumpsetSet('username'). But it is not giving me all datas anyway.</p>
