Lower custom field limit is being imposed in Group and Professional edition for Custom Settings.
Last updated 2015-09-03 ·Reference W-2105780 ·Reported By 4 users
Currently the Custom Settings object is being seen by the system as a normal custom object so the lower general custom field limit of 100 is being imposed rather than the documented 300 specific limit for custom settings.
In a Group or Professional edition organization attempt to create 101 custom fields on a custom setting, you should receive a limit reached error, or attempt to install a package containing more than 100 fields.
None currently to be able to exceed that limit. For packages that may be able to remove recently added custom settings fields to work around this but, have already released the package version please contact customer support and reference this known issue.
