title: Hide rows with no values in hierarchial grouping in crystal reports
body: <p>I have a crystal report - showing some financial data. As normal with financial data we have several general ledger accounts - which are grouped hierarchically. We are using grouping in Crystal report with some totals on hierarchical groups. </p>
  
  <p>There are some rows where the values are zero. The groups also have total of zero as a result of this. We need to hide these rows. If we try to check the sum of the field - on the group level - it hides all the parent rows (since they themselves do not have any value - only values are derived from the child rows).</p>
  
  <p>Need some way to do this in crystal?</p>
