Before I stumble into it, has anyone seen/written a little template utility to compare field labels with the external name in order to determine where in a DCT there are differences (or no differences)? Empty external names would of course be considered equal to the field label.
The https://github.com/RobertArtigas/DCT2SQL has a number of utilities that will give you the information. And the repository points to the webinars that show which one to use.You can also study the specific templates that deal with tables/fields and create your own. The other option is to go to the ClarionLive open webinar and ask there for what you are looking for.
