Click the Filter button located to the right of the desired column heading (label).
At the drop-down menu, select the appropriate option or record on which to filter. For example, select All to display all records for that particular field (column); select Blanks to display only those records that have the particular field (column) blank; or select Custom to enter specific conditions in order to display a range of records (such as to enter conditions to display all the records starting with a letter A).
Once the filter has been set for a field (column), the Filter button will appear blue to indicate a filter has been defined. If the blue Filter button appears in the button bar on a data entry screen, it indicates that the filter is set for the file when scrolling through the records (so only the filtered records appear when clicking the Next Record, Previous Record, First Record, and Last Record buttons); if desired, click the blue Filter button to remove the filter for scrolling in the file.
