Assuming you want to remove a sub-field from the eprint data object
(dataobj) and you are running at least EPrints 3.3.x then you would need
to edit the field in eprint_fields.pl under
archives/ARCHIVE_NAME/cfg/cfg.d/ to remove the sub-field from the
compound field*. If you cannot find the field in here see if you can
find the field somewhere else in the cfg.d/ directory. If it is a
compound field you will probably not need to remove this sub-field from
cfg/workflows/eprint/default.xml but you may need to remove it from
citations in cfg/citations/eprint/.
Generally, I advise against removing fields using epadmin remove_field,
just in case you decide you want to reinstate it later, if you have
remove it from all the places it is included (eprint_fields.pl,
workflows and possibly citations and eprints_render.pl and other cfg.d
files). This should mean that EPrints forgets about the field and you
shouldn't get any errors from EPrints trying to find a field that is no
*If you are trying to remove a sub-field for a core field on the data
object you may not be able to do this by editing one of the config
files. Instead you will need to edit perl_lib/EPrints/DataObj/Eprint.pm
or whatever data objects you are dealing with.
