We have a document library with many content types. They can all go through the same workflow with status updated into a column "Standard Approval". Not all documents go through the workflow, so I want to make a view that only shows document that have any status.
The Standard Approval column is not available for filtering when I create a view. Any idea why? Or how to fix it? The column was automatically added to the library when the workflow was associated.
I tried making a calculated column that returns T/F based on Standard Approval being empty or not, but that also did not work.
