title: Using OBIEE Presentation Variables in Column Formula
body: <p>I have a dashboard prompt setting a presentation variable, based on months.</p>
  
  <p>I am then trying to use the presentation variable in column formulae, however I am getting the following error when I try to preview it by selecting the month of February:</p>
  
  <pre><code>    State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError:   10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 27005] Unresolved column: "February". (HY000)
  </code></pre>
  
  <p>COlumn Formula : </p>
  
  <pre><code>      FILTER("Fact WayLeave Movements"."WayLeave Movement" USING ("Dim Date"."Month Name" IN (@{MonthName}{'January'})))
  </code></pre>
  
  <p>However when I use the same variable in the analysis filter (not in the column formula, but whole analysis) it seems to run fine. But I need the presentation variable applied on particular columns and not on all of them.</p>
  
  <p>Could anyone please advise how to achieve this or what I am doing wrong when using the presentation variable in the column formula.v</p>
