Activating Error Checking in Records

Errors occur when you add invalid tags, indicators, or subfields, or when you repeat non-repeatable subfields in tags. The MARC Editor helps you identify errors within your records. (For example, the MARC Editor displays tags that are invalid.) If your record has errors in it, Horizon still lets you save the record.

Horizon does not save a record if the error is in a tag or subfield that is a Mandatory Fatal or Non‑Repeatable Fatal tag or subfield. (For more information, see “Setting Up or Changing Valid MARC Record Components” in the Cataloging Setup Guide.)

Horizon has two different methods to reveal errors in a record:

Errors display in a different color in the record. You can change the color. (For instructions, see Choosing Field Options.)
Error messages display in a splitter window at the bottom of the record. Double-clicking on an error message positions your cursor in the record at the error so that you can correct it easily. The splitter window can be resized to show as much of the error list as you want.

You must mark Error Checking on the General tab if you want the MARC Editor to identify errors and display error messages. If you do not turn on error checking, Horizon displays “Error checking is turned off” in the error window and the errors do not show as a different color in the tags.
