Today we got errors when trying to create quotes from the opportunity (Quote related tab), not happening last week.
The problem was found to be a plugin we have that is only meant to be triggered when the quote is updated, not sure why this plugin is suddenly being triggered. We made our code a bit more robust/defensive and hit another issue.
and we think it might be related we are getting "does not have Update permissions for the lm_wiretransferapproval attribute in the quote entity", this field has field-level security on it, and all users have create privileges for this field, but only select managers have update privileges.
