Delete authority subfields

Check the Tag is set to be an Authority

To use the authority Marc Tag Maintenance option, all the subfields in your chosen Tag must have the Authority (Y/N) column set to Y (the exception to this is the 245 | Title Statement Tag which has no Authority (Y/N) setting).

To check this:

1. Launch the Amlib client
2. Go to Main > Authorities > MarcTags – the Marc Tags Within the System screen will display
3. Highlight the Tag (for example: 984) and click the F7 SubF button – the Tag Subfields screen will display:
   
4. In the Authority (Y/N) column, all subfields should be set to Y
5. If not, change all the Authority (Y/N) entries to Y (they can be changed back later if you wish to do so)
6. Click the F3 Update button when complete
