Filters remove unwanted information from a report. For example, you could exclude records before a certain date.
In the Modify Filter window, you can create your filter conditions. These are entered as separate lines that compare a variable from your data with a value. This value could be an actual figure, or 1/0 to represent true/false.
For example, to include customer accounts that are on hold, you might have something like SALES_LEDGER.ACCOUNT_ON_HOLD Equals 1.
Note: If you are editing an advanced filter, the filter will be displayed in the expression editor.
