this thread is so frustrating - the responder never solves the problem.  We want a billable expense report by category that would show XX for airfare and YY for hotels and zz for taxis.  None of the solutions proposed show the category field as a column.  None of the reports filter on category.  That's the problem we are having. I want to give my client a summary expense report by category for the expenses I bill to them.  Thanks.
