I have two tables in one file. I created a huge number of fields in table "b". And now, I need these fields in table "a", without records. I only need these fields in table "a", I do not want to create these fields again. Is it possible?

You didn't say us your version of FileMaker...

With an Advanced version you can copy all those fields and paste them into the new table.

In orther words, Vedat, Please update your profile as to Platform, OS, and FileMaker Version.

You do that by Clicking on your name at the top, and then select My Setting and then My Profile.

It's fairly rare to need the same sets of fields in two tables, and suggests that the data model is not correct. If you'd describe your setup, we'd help you structure it more efficiently.
