If you have a relationship linking the author field to the author table, you can use fields from the author table in your export.
Thanks for taking care of our problems, philmodjunk, as always!
I suppose something is wrong in my database structure.
As every Document (article) can have one or more Authors, I created a one-to-many relationships between Table Document and Table Author.
But I have no relationship between the Table Author and the Table VALUES Author, which contains the values (first name, last name) on which the value list Author is based.
Should I establish a relationship between Table Author and Table VALUES Author - and how...?
I attach a picture of the database relationships, for more clarity.
Yes that's it
Thank you very much, it now works like a charm!
