title: Dynamically declaring parameters from table
body: <p>Is it possible to dynamically create parameters from table entries?</p>
  
  <p>For example like this:</p>
  
  <pre><code>SELECTION-SCREEN BEGIN OF BLOCK example WITH TITLE text-01
      LOOP AT example_internal_table INTO example_workarea
          IF example_workarea-field = criteria.
              PARAMETERS: (example_workareafield) AS CHECKBOX.
          ENDIF.
       ENDLOOP.
  SELECTION-SCREEN END OF BLOCK example.
  </code></pre>
  
  <p>The code snippet above throws the error that example-workarea-field is not a constant. Does this mean it isn't possible to dynamically declare parameters or am I just doing it wrong? Thanks</p>
