What is "Remove Field Codes": This removes the link between the document and your RefWorks account.
When should you "Remove Field Codes"?
That sounds like a drastic step. Any steps I should take prior to Removing Field Codes?
This step is irreversible. You may want to save a copy of the paper with field codes (e.g. final_paper-field_codes.docx) and one without field codes (e.g. final_paper-no_field_codes.docx) so that you can easily revise the paper down the road. RefWorks will prompt a scary warning before you do this.
