Heading Report: Duplicate use fields

Use this option to specify the indexed fields the system should check for multiple occurrences whenever a record is indexed. Enter a list of one-letter index tags and press Enter when you are done. The usual values are: "o,b" (for bibliographic utility number and BARCODE). Some libraries also use the CALL NUMBER (c) or ISBN/ISSN (i). This checking only applies to heading reports and is not the same as duplicate checking when new records are created.
