title: Cannot add Currency field to Entity after Importing
body: <p>A custom entity was created in our DEV environment.  It originally had a Currency field, but we decided to remove it and use a Float field for simplicity.  After exporting the solution and importing it into QA for the first time, I can no longer add a Currency field to the entity in QA (and the "leftover" transactioncurrencyid column in DEV did not get migrated to QA).</p>
  
  <p>The main problem is that I cannot remove the transactioncurrencyid column and now my Filtered views are different between DEV and QA which causes our SharePoint BCS process that relies on Entity Framework to fail.</p>
  
  <p>Is there any way to completely remove a currency field without recreating the entity?</p>
  
  <p>Plan B: Is there a way to restore a past copy of the entity (prior to removing the currency) from a backup and merge it into our presently broken version? </p>
  
  <p>Plan C: any other ideas (convert EF to use Stored Procs, etc)?</p>
  
  <p>Thanks!</p>
