Adding Fields to Business Partner with User Defined Fields

Upon adding some fields to the "User Defined Fields" for the Business Partner. We find that if any changes are done to the user defined fields the following error appears. OCRD Another User modified table ‘BP’ ODBC-2039

1. Is this error because we have modified the fields improperly or should not have done it with this method?

2. Are we missing something?

Thanks for the help. I am a new user to SAP Business One and we are working through some STUFF.
