The look-up feature is not working in the EVO WO Module whether using F2 or the icon.  It gives the following error message:
 
The field: IS.WOEX.MCLASS is not part of this program and the grid will not be properly displayed.  [OK]  If I click "OK", it returns with a single Work Order line.
 
This began after I did the newest update last Friday and loaded all of the patches.   I don't know if this is a known issue or if there is something within our system that needs fixed.

When I'm using wo-b, wo-c, etc. all except wo-a, the look-up feature gives me an error.  I do not see a grid posted, so I went to the queries module and clicked on the QU-e Quick Grid launch and clicked on workorders view and got the same message:  "The field IS.WOEX.MCLASS is not part of this program and will not be displayed properly.  So maybe there is an issue with my workorders grid???  Don't know much about the grids.
