Yes if a drill-down for the text box is provided;
otherwise, No. The default value is No.
Remarks
Drill-downs are a system-wide feature of FlowFields
that let you see the underlying transactions that make up the
information shown in the FlowField. For example, if the FlowField
shows an account balance, then providing a drill-down for this text
box allows the user to quickly see the various transactions that
make up the balance shown in the field.
